Scientists See Advances in Deep Learning, a Part of Artificial Intelligence

Hao Zhang/The New York Times

A voice recognition program translated a speech given by Richard F. Rashid, Microsoft’s top scientist, into Mandarin Chinese.

Using an artificial intelligence technique inspired by theories about how the brain recognizes patterns, technology companies are reporting startling gains in fields as diverse as computer vision, speech recognition and the identification of promising new molecules for designing drugs.

The advances have led to widespread enthusiasm among researchers who design software to perform human activities like seeing, listening and thinking. They offer the promise of machines that converse with humans and perform tasks like driving cars and working in factories, raising the specter of automated robots that could replace human workers.

The technology, called deep learning, has already been put to use in services like Apple’s Siri virtual personal assistant, which is based on Nuance Communications’ speech recognition service, and in Google’s Street View, which uses machine vision to identify specific addresses.

But what is new in recent months is the growing speed and accuracy of deep-learning programs, often called artificial neural networks or just “neural nets” for their resemblance to the neural connections in the brain.

“There has been a number of stunning new results with deep-learning methods,” said Yann LeCun, a computer scientist at New York University who did pioneering research in handwriting recognition at Bell Laboratories. “The kind of jump we are seeing in the accuracy of these systems is very rare indeed.”

Artificial intelligence researchers are acutely aware of the dangers of being overly optimistic. Their field has long been plagued by outbursts of misplaced enthusiasm followed by equally striking declines.

In the 1960s, some computer scientists believed that a workable artificial intelligence system was just 10 years away. In the 1980s, a wave of commercial start-ups collapsed, leading to what some people called the “A.I. winter.”

But recent achievements have impressed a wide spectrum of computer experts. In October, for example, a team of graduate students studying with the University of Toronto computer scientist Geoffrey E. Hinton won the top prize in a contest sponsored by Merck to design software to help find molecules that might lead to new drugs.

From a data set describing the chemical structure of 15 different molecules, they used deep-learning software to determine which molecule was most likely to be an effective drug agent.

The achievement was particularly impressive because the team decided to enter the contest at the last minute and designed its software with no specific knowledge about how the molecules bind to their targets. The students were also working with a relatively small set of data; neural nets typically perform well only with very large ones.

“This is a really breathtaking result because it is the first time that deep learning won, and more significantly it won on a data set that it wouldn’t have been expected to win at,” said Anthony Goldbloom, chief executive and founder of Kaggle, a company that organizes data science competitions, including the Merck contest.

Advances in pattern recognition hold implications not just for drug development but for an array of applications, including marketing and law enforcement. With greater accuracy, for example, marketers can comb large databases of consumer behavior to get more precise information on buying habits. And improvements in facial recognition are likely to make surveillance technology cheaper and more commonplace.

Artificial neural networks, an idea going back to the 1950s, seek to mimic the way the brain absorbs information and learns from it. In recent decades, Dr. Hinton, 64 (a great-great-grandson of the 19th-century mathematician George Boole, whose work in logic is the foundation for modern digital computers), has pioneered powerful new techniques for helping the artificial networks recognize patterns.

Modern artificial neural networks are composed of an array of software components, divided into inputs, hidden layers and outputs. The arrays can be “trained” by repeated exposures to recognize patterns like images or sounds.

These techniques, aided by the growing speed and power of modern computers, have led to rapid improvements in speech recognition, drug discovery and computer vision.

Deep-learning systems have recently outperformed humans in certain limited recognition tests.

Last year, for example, a program created by scientists at the Swiss A. I. Lab at the University of Lugano won a pattern recognition contest by outperforming both competing software systems and a human expert in identifying images in a database of German traffic signs.

The winning program accurately identified 99.46 percent of the images in a set of 50,000; the top score in a group of 32 human participants was 99.22 percent, and the average for the humans was 98.84 percent.

Lining up even earlier for Black Friday becomes a shop priority

In a tradition that seems to take a bigger slice of Thanksgiving every year, hordes of deal-sniffing shoppers descended on Southland stores Thursday, elbowing their way in search of toys, video games and that time-honored Black Friday symbol: cut-rate television sets. As nightfall came, they huddled in long lines, clutching coupons and hatching shopping strategies.

Rebecca Abbott, 42, of Torrance had it down to a science Thursday night. The accountant said she was out the door of the local Toys R Us store in 20 minutes with a shopping cart full of Christmas gifts for her two daughters. 

Her fourth time shopping on Black Friday, Abbott had spent a few hours in Toys R Us the day before scoping out her plan of attack. The first item on her list: a Rockstar Mickey Mouse doll, normally priced at $59.99 but selling for just $19.99.

"You have to have a strategy for this Black Friday madness," she said as she headed for the door. "First-timers will walk around all day looking at deals," Abbott said. "I got in, grabbed my stuff and got out." Her cart was overflowing with large toys — primarily Barbie and Mickey Mouse items. 

PHOTOS: Black Friday shoppers hunt for deals

At a Wal-Mart in Panorama City, just after 8 p.m., "it was really crazy, but you could still walk," said Marya Huaman, 23, as she left the store with her dad, her two infant sons and three bags full of Fisher-Price toys.

"No, you couldn't," scoffed her father, Edward Huaman. "I didn't see anyone fighting, but they will be soon. This is madness."

Last year, Thanksgiving night was marred by a pepper spray "shopping rage" incident at a Wal-Mart in Porter Ranch that injured at least seven people and forced employees to evacuate part of the store. One person was hospitalized.

Los Angeles Police Cmdr. Andy Smith said Thursday that the night appeared to be running smoothly across Los Angeles. "In general, I think things have gone really well," he said. "It sounds like the stores have taken proper precautions and everyone is aware of the hazards of Black Friday."

After retailers last year moved the opening bell for Black Friday sales to midnight, this year there were even more customers eager to get a jump on the traditional kickoff to the holiday shopping season. Wal-Mart, Sears and Toys R Us began rolling out their door busters at 8 p.m. on Turkey Day, followed by Target at 9 p.m. Macy's, Kohl's and Best Buy were set to open at midnight.

A handful of chains such as Kmart and Old Navy also had daytime hours on Thursday. And online merchants were touting bargains all day and night.

About 147 million shoppers are expected this all-important holiday weekend, with more logging in for online specials by Cyber Monday, according to the National Retail Federation. In all, the trade group estimated that holidays sales will rise 4.1% this year, to $586 billion.

"Though the Black Friday tradition is here to stay, there's no question that it has changed in recent years," NRF Chief Executive Matthew Shay said in a statement.

Many shoppers were perfectly content to queue up. At Best Buy electronic stores across the Southland, people waited for hours — and sometimes days — in tents before the midnight opening.

But many workers were angry about spending Turkey Day away from loved ones.

Frustrated retail employees and families have taken to creating online petitions at Change.org to beg companies not to cut into Thanksgiving dinners. More than 20 online petitions have popped up in recent weeks. Lines grew throughout the afternoon and into the evening as anxious shoppers surveyed the competition in line.

Throughout Southern California there were reports of lines wrapped around stores. In Glendale, more than 750 shoppers were lined up outside the Target at the Galleria.

For shoppers who just couldn't wait until Thursday night — much less Black Friday — some retailers opened their doors all day on Thanksgiving.

The sales weren't quite as glorious as the Black Friday specials that stores promise to roll out later. But they were pretty good nonetheless, shoppers said.

JoAnne Garcia walked into Kmart in Burbank in search of a roasting pan in which to cook her turkey. She walked out 90 minutes later, having shelled out $491, including $329 for an RCA 39-inch LCD flat-panel TV.

"The roasting pan was $14.99," Garcia said, laughing at how much she spent as she rolled her cart to the parking lot.

To the 53-year-old aerospace machinist, shopping on Thanksgiving made perfect sense.

Standing near a store display touting "Freak Out Pricing," Garcia explained her theory about shopping while cooking. "You get up, throw your turkey in the oven, and you come back and it's all done."

The New Old Age Blog: Home Health Care Help by the Hour

Here is a bright idea that ought to spread: You call your home care agency and say you will need your mother’s aide for the normal two hours on Monday and Wednesday, but for just half an hour (to drive her to a doctor’s office) on Tuesday, then 90 minutes on Thursday. And the agency says, “Sure.”

It sounds logical to hire someone to help — with bathing, dressing, errands, meal preparation, medication reminders – for only as many hours as an older adult needs assistance. But it is actually unusual for companies to offer such flexibility.

The majority of agencies require a four-hour minimum. Having to spend $80  — the national average cost for home care is $21 an hour — if you only need $40 worth of help is a big barrier for families trying to keep their elderly relatives living at home longer. A few agencies allow you to hire for fewer than four hours, but at higher rates.

But Mission Healthcare in San Diego, Calif., a three-year-old agency that began with Medicare-certified skilled home nursing and hospice care, expanded to general home care this summer and decided that clients should be able to specify how much help they want – in 15-minute increments — and will pay for.

“We’ll come for as long as they need us to,” said Mark Kimsey, one of Mission’s four directors. “In one hour, a well-trained caregiver can get the client bathed and dressed, prepare three meals and have them organized for the day.” (I have to think that is a speedy caregiver with a not-too-frail client, but still … )

Can Mission, which charges $19 to $20 an hour, actually make money this way? Though overall the agency serves 1,100 clients, its fledgling home care business is still small: 30 aides caring for just 60 clients. The aides can get benefits if they work enough hours, a bonus for them and for consumers (better employees, lower turnover), but an additional cost for the company.

The directors say they are profitable already, and that the approach will succeed because more people will like the flexibility and potential savings, and sign up. It is also true, let’s acknowledge, that a person who can get by with an hour or two a day for now may well need more help eventually, a boost for Mission’s bottom line.

Competitors are no doubt watching to see if this works. I’m curious, too, to see if the policy catches on. “Consumers can change the marketplace if they want to,” Mr. Kimsey said. It would be nice to think that is true.

Would you use this kind of hourly service, if it were available?

News Analysis: Case Casts a Shadow on a Hedge Fund Mogul

In 2010, the billionaire hedge fund manager Steven A. Cohen gave a rare interview to Vanity Fair. He said that he wanted to combat persistent rumors that his firm, SAC Capital Advisors, routinely violated securities laws by trading on confidential information.

“In some respects I feel like Don Quixote fighting windmills,” Mr. Cohen said at the time. “There’s a perception, and I’m trying to fight that perception.”

Federal prosecutors only heightened that perception on Tuesday, bringing a criminal case against a former SAC employee in what Preet Bharara, the United States attorney in Manhattan, who brought the charges in Federal District Court in Manhattan, called the most lucrative insider trading scheme ever charged.

And for the first time, the evidence suggests that Mr. Cohen participated in trades that the government says illegally used insider information — though prosecutors have not said that Mr. Cohen himself knew the information was confidential, and he has not been charged.

Any prosecution of Mr. Cohen would most likely hinge on the cooperation of Mathew Martoma, the former SAC employee charged in the case. Mr. Bharara said in the charges that Mr. Martoma obtained secret data from a doctor about clinical trials for an Alzheimer’s drug being developed by the companies Elan and Wyeth. The information enabled SAC to avoid losses of almost $194 million on the stocks, which it sold and then bet against, reaping $83 million in profit — a total benefit to the firm of more than $276 million. SAC executed the trades shortly after Mr. Martoma e-mailed Mr. Cohen and said he needed to discuss something important.

As to Mr. Cohen’s potential culpability in the case, the crucial issue is what Mr. Martoma told Mr. Cohen that led SAC to quickly dump $700 million worth of stock. Did he provide his boss details on why he had turned sour on Wyeth and Elan? Specifically, did he share the leak about the drug trial’s negative results and identify the source of the secret information? Through a spokesman, he said he was confident he had acted appropriately.

It appears, for now, that Mr. Martoma will fight the charges. But the crucial question, as it relates to Mr. Cohen, is whether at some point Mr. Martoma will reverse course, admit to insider trading and agree to help the government build a case against his former boss. Without Mr. Martoma’s cooperation, it is unlikely that the prosecutors have enough evidence to charge Mr. Cohen.

“This has all the markings of a case where the government goes after the smaller fish and then pressures them to flip so they can get the whale,” said Bradley D. Simon, a criminal defense lawyer and former federal prosecutor in New York.

The government has several weapons for its effort to persuade Mr. Martoma to agree to a plea, including the stiff sentences for insider trading. Under the federal sentencing guidelines, Mr. Martoma could receive more than 15 years in prison, a term that could be reduced — or avoided altogether — if he agreed to testify against Mr. Cohen.

F.B.I. agents arrested Mr. Martoma, 38, early Tuesday morning at his home in Boca Raton, Fla., a nearly 8,000-square-foot Mediterranean-style mansion on the grounds of the elite Royal Palm Yacht and Country Club. He lives there with his wife, a pediatrician, and three children. A graduate of Duke University and Stanford University’s business school, Mr. Martoma is expected to make an appearance in Federal District Court in Manhattan Monday morning.

Described by a former colleague as low-key and cerebral, Mr. Martoma is one of scores of traders who have earned millions of dollars working under Mr. Cohen and feeding him their best investment ideas. He joined SAC in 2006. In 2008, the year he participated in the alleged illegal trade, the firm paid Mr. Martoma a $9.3 million bonus. But SAC fired him in 2010 after two years of subpar performance.

Charles A. Stillman, a lawyer for Mr. Martoma, said on the day of his arrest, “What happened today is only the beginning of a process that we are confident will lead to Mr. Martoma’s full exoneration.”

It is no secret that the government has been circling Mr. Cohen since the middle of last decade, when it began its crackdown on insider trading, an investigation that has resulted in more than 70 criminal charges. Prosecutors have already linked five former SAC employees to insider trading while at the fund — securing three convictions — though none of those cases connected Mr. Cohen to any illicit activity. But the complaint filed on Tuesday puts Mr. Cohen at the center of the supposed improper conduct.

Mr. Cohen, 56, is a legend on Wall Street, having amassed a multibillion-dollar fortune by posting phenomenal investment returns averaging about 30 percent over the last two decades. Starting with a $25 million grubstake, SAC now manages about $13 billion and has 900 employees across the globe. Mr. Cohen has also emerged as a major force in the art world, owning an eclectic collection that includes works by Picasso, Warhol and Cézanne.

Prosecutors have constructed their case against Mr. Martoma, and increased the pressure on him, by securing the cooperation of Dr. Sidney Gilman, the doctor who supposedly leaked to him the Alzheimer’s drug’s trial data. The case against Mr. Martoma will depend largely on Dr. Gilman’s credibility as a witness.

Dr. Gilman, 80, a neurologist at the University of Michigan medical school, was hired by Elan and Wyeth to monitor the trial’s safety, which gave him access to secret information about the results. SAC retained Dr. Gilman as a consultant and paid him about $108,000.

At first, Dr. Gilman’s reports on the trial’s progress were positive, and SAC built a position in the two drug makers worth approximately $700 million, according to prosecutors. But then, on July 17, 2008, Dr. Gilman told Mr. Martoma that there were problems with the drug, the government said.

A few days later, Mr. Martoma e-mailed Mr. Cohen that he needed to discuss something “important,” and the two then spoke for 20 minutes, according to court filings. Over the next four days, at Mr. Cohen’s direction, SAC Capital jettisoned its entire position in the two stocks and then placed a big negative bet on the drug makers, the government said.

On July 30, after disclosure of the poor trial results, shares of Elan and Wyeth sank. According to the prosecutors’ calculations, SAC would have lost about $194 million had it kept the stock; taking a short position instead generated profits of about $83 million.

Dr. Gilman and the Justice Department have entered into a nonprosecution agreement under which he will cooperate in exchange for not being criminally charged.

Thus far, any potential evidence against Mr. Cohen is entirely circumstantial. The government’s complaint includes e-mails about secretly selling the Elan and Wyeth shares through esoteric methods like algorithms and dark pools. But that is common practice among large, sophisticated funds that do not want to alert competitors or move the stock too much. Moreover, while SAC dumped its large positions in the two stocks quickly — raising the question of what prompted it to do so — Mr. Cohen is known for a rapid-fire trading style. He frequently moves aggressively in and out of stocks while processing gobs of information fed to him by his underlings.

It would be difficult for a jury to infer anything incriminating just from the way these trades were executed.

The government in this case also lacks the powerful wiretap evidence that it has used to convict dozens others, including Raj Rajaratnam, the head of the Galleon Group. Federal agents did wiretap Mr. Cohen’s home telephone for a short period in 2008, according to a person with direct knowledge of the investigation who spoke only on the condition of anonymity. But it is unclear whether the eavesdropping, which was first reported by The Wall Street Journal, yielded any fruit.

Even without incriminating wiretap evidence, the government has brought cases that rely almost entirely on witnesses testifying against their bosses.

One of those cases is now under way in federal court in Manhattan. Prosecutors are currently trying the former hedge fund portfolio managers Anthony Chiasson of Level Global Investors and Todd Newman of Diamondback Capital Management. Prosecutors say that the two were part of a conspiracy that made about $68 million illegally trading technology stocks.

The outcome of that trial is expected to depend largely on whether the jury believes the testimony of two cooperating witnesses who admitted to the conspiracy — Spyridon Adondakis and Jesse Tortora, former junior analysts at Level Global and Diamondback. The two say they shared secret information with the defendants. Defense lawyers have attacked the witnesses’ credibility, accusing them of lying to avoid prison.

That case, too, has strong ties to SAC. Mr. Chiasson and his co-founder were star traders under Mr. Cohen before starting the now-defunct Level Global. And the owners of Diamondback are both former SAC employees; one is Mr. Cohen’s brother-in-law, Richard Schimel. Diamondback, which continues to operate, has not been accused of wrongdoing.

“SAC’s extraordinary profits have always been something of a market mystery,” said Sebastian Mallaby, the author of “More Money Than God,” a book on the history of hedge funds. “As more and more lawsuits implicate former SAC traders, we may at last understand where SAC’s profits came from.”

New California legislators get a warm welcome — from lobbyists

SACRAMENTO — The day after being elected to the state Assembly, several incoming lawmakers were in AT&T's luxury suite at the Sacramento sports arena, watching the Kings with the company's top Capitol executive.

The next day, the California Dental Assn. feted the state's freshman legislators. That was before more than 20 legislators jetted off to Hawaii, China, Brazil, New Zealand and other locales — with some trips paid for in large part by healthcare, energy and communications companies.

"It's the start of lobbyists inculcating them, saying 'Hey guys, line up and receive your gifts,' " said Bob Stern, former chief counsel to the state Fair Political Practices Commission.

It's a new day in Sacramento, with one of the largest-ever freshman classes elected in districts drawn for the first time by an independent, bipartisan commission.

And the lobbying campaign to shape their minds has begun.

The intent of the redistricting — as well as a rule change that allows lawmakers to serve up to 12 years in either legislative house — was to make the Capitol more accountable. In theory, the changes would reduce the influence of lobbyists and give lawmakers more time to gain expertise and independence.

But old traditions die hard.

Following the example of veteran legislative leaders, including Assembly Speaker John Pérez (D-Los Angeles), more than a dozen Democratic freshmen headed off to AT&T's suite at the Sleep Train Arena.

Lawmakers are not allowed to take more than $420 in gifts per year, and they are supposed to report what they receive. But sidestepping the rules is hardly a challenge.

The freshmen who joined Pérez didn't have to report the value of their tickets because the gathering was hosted by the state Democratic Party.

Jose Medina, a newly elected assemblyman from Riverside, said the event was totally appropriate. Spending time with lobbyists is "part of my job,'' he said.

"At the end of the day, I'll make my decision based on what is best for the people I represent," he said.

Jim Frazier, a freshman assemblyman from Oakley, called the evening "a great opportunity to start meeting the people who worked so hard to represent their districts."

Other freshman Democrats in the suite included Ken Cooley of Rancho Cordova, Marc Levine of San Rafael, Phil Ting of San Francisco, Kevin Mullin of South San Francisco, Rudy Salas of Bakersfield, Bill Quirk of Hayward and Reggie Jones-Sawyer of Los Angeles.

Jones-Sawyer was one of 15 legislators who flew a few days later to Maui for a five-day conference at the Fairmont Kea Lani organized by the California Independent Voter Project.

The group, which paid some of the legislators' travel expenses, has been funded over the years by tobacco giant Altria Group Inc., Southern California Edison, Eli Lilly & Co., Pacific Gas & Electric Co., the California Beer & Beverage Distributors, the Pharmaceutical Research and Manufacturers Assn., Chevron Corp. and the state prison guards union.

In between rounds of golf and poolside lounging, the sponsors talked with lawmakers.

"I was learning about the issues," said Jones-Sawyer, the only freshman on the trip. "There were some things I didn't know — such as how businesses really need help to flourish here in California."

Phillip Ung, an advocate with California Common Cause, said he found the explanations bewildering.

"They have obviously convinced themselves that the people's business is best solved poolside with mai tais in hand," he said. "Congress banned this type of travel years ago."

Other lawmakers went to China, Australia, New Zealand or Brazil this month, in some cases paid for by special interests.

Those in Brazil were sponsored by the California Foundation on the Environment and the Economy, which is bankrolled by Chevron, PG&E, the International Brotherhood of Electrical Workers and Southern California Edison, among others.

The sponsors sent representatives to accompany Assemblyman Steven Bradford (D-Gardena), who is chairman of the Assembly Utilities and Commerce Committee, as well as Sens. Anthony Cannella (R-Ceres), Mimi Walters (R-Laguna Niguel), Bill Emmerson (R-Hemet) and Michael Rubio (D-East Bakersfield).

The group paid for airfare, hotels, meals and ground transportation, said P.J. Johnston, a spokesman for the nonprofit foundation.

The lawmakers were there to meet with government and business leaders in Brazil to discuss reducing pollution, setting low-carbon fuel standards, transportation projects and other issues, Johnston said.

"Brazil provides real-world insight into issues California's decision-makers are grappling with, putting them in a larger perspective and offering lessons learned from a country with a rich history of challenges and successes in these areas," he said.

Before the iPad, There Was the Honeywell Kitchen Computer

In the winter of 1969, the Neiman Marcus Christmas catalog offered to computerize your kitchen.

Cooking up a gourmet holiday meal will be a snap, the department store promised. Push a few buttons, and — presto! — a shiny orange-red, white, and black machine will compute the perfect five-course meal. No more silly culinary errors. The days of your wife slaving away in her Chanel apron will vanish into memory, and all those blinking lights will add to your holiday cheer.

All you needed was space for this 100-pound machine. And about $10,000. And a teletype. And a paper tape reader. And some serious engineering skills.

Needless to say, Neiman Marcus’ male-topian fantasy never materialized. The department store didn’t sell a single Honeywell Kitchen Computer, and it may never have intended to. The ad was no more than a publicity stunt, just like the stores ads for your very own Noah’s Ark and His-and-Hers airplanes in Christmas catalogs past.

The computer did exist. It was based on one of the Series 16 minicomputers from Honeywell, an early computer maker that would later help power the Arpanet, the forerunner to the modern internet. It’s just that this machine didn’t quite live up to the image of the modern computer that so often turned up in the popular imagination in the late ’60s and ’70s. It’s a bit like the talking Honeywell that turned up two years earlier in the Michael Caine spy flick The Billion Dollar Brain.

The Neiman Marcus ad was “a brilliant idea” and “wonderful publicity,” says Gardner Hendrie, who served as program manager for the Honeywell machine at the heart of the Kitchen Computer and is now a trustee of the Computer History Museum in Mountain View, California. “But I thought the packaging was probably a waste of time and wouldn’t sell.”

The Honeywell Kitchen Computer was really a 16-bit business machine called the H316 minicomputer. The H316 was available as a table-top machine or a machine you could mount on a rack, but Kitchen Computer was based on a version that was shoehorned into a futuristic, Jetsons-like pedestal. People did actually buy this machine, but not very many people.

“I don’t think it was a very popular style. Ninety-five percent of people wanted to build it into a [larger] system…. They were sticking them in racks,” says Dag Spicer, curator of the Computer History Museum, which is home to the only Kitchen Computer in existence. “The people buying these are engineers. They don’t care what it looks like.”

What they cared about were machines that could manage industrial, military, aerospace, research, and scientific projects — not sleek ines and a built-in writing desk. They wanted a minicomputer that could connect to a teletype and a paper tape reader.

An engineer would type a program in human-readable form, and the teletype would spit out the program on paper tape, translating the code into a series of punched holes and spaces. The paper tape reader could then read the holes and spaces as ones and zeros. The paper tape was “like a floppy disk, circa 1960. It’s a personal means of data storage,” Spicer says.

Without a teletype, a programmer would need to enter software into the Honeywell using the 16 buttons on the front panel, each of which corresponds to a bit. A pressed button represented a one, and un-pushed button signaled a zero. “The chances that you would get a program right doing it one bit at a time like that were so low,” Spicer said. “The first peripheral people bought for [the Honeywell] was a teletype so they could speak to it.”

Now try to imagine all that in late 1960s kitchen. A full H316 system wouldn’t have fit in most kitchens, says design historian Paul Atkinson of Britain’s Sheffield Halam University. Plus, it would have looked entirely out of place. The thought that an average person, like a housewife, could have used it to streamline chores like cooking or bookkeeping was ridiculous, even if she aced the two-week programming course included in the $10,600 price tag.

If the lady of the house wanted to build her family’s dinner around broccoli, she’d have to code in the green veggie as 0001101000. The kitchen computer would then suggest foods to pair with broccoli from its database by “speaking” its recommendations as a series of flashing lights. Think of a primitive version of KITT, without the sexy voice.

“What that means is you have to be able to decode the lights in your brain,” says Spicer of the Computer History Museum. Or at least remember the pattern and look up what it meant. At that rate, dinner might be ready next week. “The reason this is such a joke, a gag item, was that there was no real human-readable I/O [input/output] for it.”

It may not have worked in a practical sense, but at least it got people thinking about computers as consumer products. The concept of kitchen and home computers had already been circulating in popular culture by the time Neiman Marcus’ kitchen computer graced its Christmas catalog. In The Jetsons, which aired in the early 1960s, humans lived in a tech-happy world alongside robots and computers. In 1966, Westinghouse Corporation engineer Jim Sutherland built the Electronic Computing Home Operator (ECHO IV) to automate storing recipes, controlling home temperature, keeping track of household inventory, and conserving energy.

A year later, Philco-Ford Corporation released A.D. 1999, a short film that portrayed what life would be like at the end of the century. A scene in the kitchen of the future shows a family teleconferencing while mom plans dinner with the help of a flat-screen computer that knows how many calories dad is allowed to have. And after seeing the Neiman Marcus Kitchen Computer, Gordon Bell of Digital Equipment Corporation, a leading company in the minicomputer industry, sent out a congeries on the computer-in-the-home market in which he called the trend “inevitable.” And he was right.

The dedicated kitchen computer never quite happened. Since the Honeywell, there have been several attempts to revive the idea, like Electrolux’s Screenfridge and the HP Touch Smart, but none have really caught on. “In a way, the technology is in search of a problem,” said Spicer. “There is just this persistent meme of having computers in the kitchen, and somehow that’s going to create more leisure time.”

That said, this holiday season, so many of you will cook our meals with the help of iPads and laptops and smartphones, as you told us just last week. They’re smaller than the Honeywell. They’re cheaper. They don’t require a teletype. They’re not attached to your fridge. And you can take them outside the kitchen and use them for so many other things. Sometimes the future isn’t what a catalog tells us it will be. Sometimes, it’s better.

Chevy Chase is leaving NBC’s sitcom ‘Community’

LOS ANGELES (AP) — The NBC series “Community” will finish the season without Chevy Chase.

Sony Pictures Television said Wednesday that the actor is leaving the sitcom by mutual agreement with producers.

His immediate departure means he won’t be included in the last episode or two of the show’s 13-episode season, which is still in production.

Chase had a rocky tenure playing a bored and wealthy man who enrolls in community college. The actor publicly expressed unhappiness at working on a sitcom and feuded last year with the show’s creator and former executive producer, Dan Harmon.

The fourth-season premiere of “Community” is Feb. 7, when it makes a delayed return to the 8 p.m. EST Thursday time slot. The show’s ensemble cast includes Joel McHale and Donald Glover.

Recipes for Health: Apple Pear Strudel — Recipes for Health

Andrew Scrivani for The New York Times

This strudel is made with phyllo dough. When I tested it the first time, I found that I had enough filling for two strudels. Rather than cut the amount of filling, I increased the number of strudels to 2, as this is a dessert you can assemble and keep, unbaked, in the freezer.

Filling for 2 strudels:

1/2 pound mixed dried fruit, like raisins, currants, chopped dried figs, chopped dried apricots, dried cranberries

1 1/2 pounds apples (3 large) (I recommend Braeburns), peeled, cored and cut in 1/2-inch dice

1 tablespoon fresh lemon juice

2 tablespoons unsalted butter for cooking the apples

1/4 cup (50 grams) brown sugar

1 teaspoon vanilla

1 teaspoon cinnamon

1/2 teaspoon freshly grated nutmeg

1/4 cup (30 grams) chopped or slivered almonds

3/4 pound (1 large or 2 small) ripe but firm pears, peeled, cored and cut in 1/2-inch dice

For each strudel:

8 sheets phyllo dough

7/8 cup (100 grams) almond powder, divided

1 1/2 ounces butter, melted, for brushing the phyllo

1. Preheat the oven to 375 degrees. Line 2 sheet pans with parchment.

2. Place the dried fruit in a bowl and pour on hot or boiling water to cover. Let sit 5 minutes, and drain. Toss the apples with the lemon juice.

3. Heat a large, heavy frying pan over high heat and add 2 tablespoons butter. Wait until it becomes light brown and carefully add the apples and the sugar. Do not add the apples until the pan and the butter are hot enough, or they won’t sear properly and retain their juice. But be careful when you add them so that the hot butter doesn’t splatter. When the apples are brown on one side, add the vanilla, cinnamon, nutmeg and almonds, flip the apples and continue to sauté until golden brown, about 5 to 7 minutes. Stir in the pears and dried fruit, then scrape out onto one of the lined sheet pans and allow to cool completely. Divide into two equal portions (easiest to do this if you weigh it).

4. Place 8 sheets of phyllo dough on your work surface. Cover with a dish towel and place another, damp dish towel on top of the first towel. Place a sheet of parchment on your work surface horizontally, with the long edge close to you. Lay a sheet of phyllo dough on the parchment. Brush lightly with butter and top with the next sheet. Continue to layer all eight sheets, brushing each one with butter before topping with the next one.

5. Brush the top sheet of phyllo dough with butter. Sprinkle on half of the almond powder (50 grams). With the other half, create a line 3 inches from the base of the dough, leaving a 2 1/2-inch margin on the sides. Top this line with one portion of the fruit mixture. Fold the bottom edge of the phyllo up over the filling, then fold the ends over and roll up like a burrito. Using the parchment paper to help you, lift the strudel and place it on the other parchment-lined baking sheet. Brush with butter and make 3 or 4 slits on the diagonal along the length of the strudel. Repeat with the other sheets of phyllo to make a second strudel. If you are freezing one of them, double-wrap tightly in plastic.

6. Place the strudel in the oven and bake 20 minutes. Remove from the oven, brush again with butter, rotate the pan and return to the oven. Continue to bake for another 20 to 25 minutes, or until golden brown. Remove from the heat and allow to cool for at least 15 minutes. Serve warm or room temperature.

Yield: 2 strudels, each serving 8

Advance preparation: The fruit filling will keep for a couple of days in the refrigerator. The strudel can be baked a few hours before serving it. Recrisp in a medium oven for 10 minutes. It can also be frozen before baking, double-wrapped in plastic. Transfer directly from the freezer to the oven and add 10 minutes to the baking time.

Ex-hedge fund manager Mathew Martoma accused of insider trading

NEW YORK — After building a huge stake in two drug companies, hedge fund manager Mathew Martoma told his powerful boss on a Sunday morning that they had to immediately dump their position.

It was an unusual request even by the outsized standards of Wall Street, but the hedge fund quietly liquidated its $700-million position within days.

Federal authorities suggested Tuesday why Martoma was in such a hurry back in 2008 — he'd allegedly gotten an illegal tip about big problems with the companies' developmental Alzheimer's drug. It was the most profitable insider-trading scheme in U.S. history, netting $276 million in profit and avoided losses, according to prosecutors.

But it resulted in criminal charges against Martoma and a swirl of questions about his boss, Steven Cohen, who is one of the most celebrated figures on Wall Street.

Cohen is worth an estimated $8.8 billion and lives in a 35,000-square-foot mansion in Greenwich, Conn., that includes an ice rink and Zamboni machine. He helped bankroll a failed bid last year to buy the Dodgers.

His firm, SAC Capital Advisors, has drawn attention in recent years as the government launched a massive crackdown on insider trading.

The hedge fund reportedly told clients it received a subpoena seeking a "broad" array of documents in late 2010. Around that time, two hedge funds founded by SAC alumni were raided by FBI agents as the government pursued its insider probe.

Martoma is the fifth person affiliated with SAC Capital to be charged in insider-related cases. Cohen's ex-wife sued him three years ago, alleging that her former husband amassed his fortune partly through insider trading.

Cohen was not named in the dual federal and civil complaints Tuesday, but experts said the government might have him in its sights.

In a civil complaint filed by the Securities and Exchange Commission, Cohen is referred to as "Portfolio Manager A," the Wall Street Journal reported. The companion criminal action lists Cohen as the "owner" of hedge funds involved in the scheme, the Journal said.

"He is to hedge funds what Michael Milken, back in the '80s, was to investment bankers," said John Coffee, a law professor at Columbia University. "The government seems to be within one move of getting a key witness against one of the most important figures in the new universe of hedge funds."

An SAC spokesman disputed that.

"Mr. Cohen and SAC are confident that they have acted appropriately and will continue to cooperate with the government's inquiry," the spokesman said in a statement.

Martoma's lawyer denied wrongdoing by his client.

"Mathew Martoma was an exceptional portfolio manager who succeeded through hard work and the dogged pursuit of information in the public domain," the lawyer, Charles Stillman, said in a statement. "What happened today is only the beginning of a process that we are confident will lead to Mr. Martoma's full exoneration."

The case revolves around a drug developed by Irish biotechnology company Elan Corp. and New Jersey-based pharmaceutical giant Wyeth, which was acquired by Pfizer Inc. in 2009.

Martoma specialized in healthcare stocks for an SAC unit called CR Intrinsic. He got a series of tips about the drug, bapineuzumab, from Dr. Sidney Gilman, a neurology professor at the University of Michigan, the government said.

Gilman consulted for Elan and Wyeth. Martoma was connected to Gilman by an "expert network" that matches investors with specialists in various fields.

After initial optimism about bapineuzumab, a clinical trial showed disappointing results. Gilman allegedly alerted Martoma to the test results shortly before public disclosure in July 2008, prompting Martoma's 8:52 a.m. email to Cohen.

The subsequent selling accounted for a whopping 20% of Elan's trading volume and 11% of Wyeth's at one point, according to the FBI. The fund even bet against the companies by "shorting" their stocks.

"And so, just like that, overnight, Martoma went from bull to bear as he tried to dig his hedge fund out of a massive hole," Preet Bharara, the U.S. attorney in Manhattan, said at a news conference.

Elan shares slumped 42% the day after the results were revealed.

Martoma is the fifth former SAC employee and the 73rd defendant accused of insider trading by Bharara's office since August 2009. Of those defendants, 69 have been convicted, most of them through plea agreements.

Bharara's office agreed to not prosecute Gilman, 80, in exchange for his testimony.

Martoma, 38, got an annual bonus of $9.3 million, primarily stemming from the profits in Elan stock, according to the government.

He got no bonus after disappointing years in 2009 and 2010 and was terminated in 2010. According to the government, an email recommending his termination said Martoma appeared to be a "one trick pony with Elan."
