Rolling Stones mark 50th year with London show

LONDON (AP) — The Rolling Stones made a triumphant return to the London stage on Sunday night in the first of five concerts to mark the 50th anniversary of their debut as an American-oriented blues band.

They showed no signs of wear and tear — except on their aging, heavily lined faces — as frontman Mick Jagger swaggered and strutted through a stellar two-and-a-half hour show. He looked remarkably trim and fit and was in top vocal form.

The Stones passed the half-century mark in style at the sometimes emotional gig that saw former bassist Bill Wyman and guitar master Mick Taylor join their old mates in front of a packed crowd at London's 02 Arena.

It was the first of five mega-shows to mark the passage of 50 years since the band first appeared in a small London pub determined to pay homage to the masters of American blues.

Jagger, in skin-tight black pants, a black shirt and a sparkly tie, took time out from singing to thank the crowd for its loyalty.

"It's amazing that we're still doing this, and it's amazing that you're still buying our records and coming to our shows," he said. "Thank you, thank you, thank you."

Lead guitarist Keith Richards, whose survival has surprised many who thought he would succumb to drugs and drink, was blunter: "We made it," he said. "I'm happy to see you. I'm happy to see anybody."

But the band's fiery music was no joke, fuelled by an incandescent guest appearance by Taylor, who played lead guitar on a stunning extended version of the ominous "Midnight Rambler," and Mary J. Blige, who shook the house in a duet with Jagger on "Gimme Shelter."

The 50th anniversary show, which will be followed by one more in London, then three in the greater New York area, lacked some of the band's customary bravado — the "world's greatest rock 'n' roll band" intro was shelved — and there were some rare nostalgic touches.

Even the famously taciturn Wyman briefly cracked a smile when trading quips with Richards and Ronnie Wood.

The concert started with a brief video tribute from luminaries like Elton John, Iggy Pop and Johnny Depp, who praised the Stones for their audacity and staying power. The Stones' show contained an extended video homage to the American trailblazers who shaped their music: Muddy Waters, John Lee Hooker, Otis Redding, Bob Dylan, Johnny Cash and others. The montage included rare footage of the young Elvis Presley.

The Stones began their professional career imitating the Americans whose music they cherished, but they quickly developed their own style, spawning hundreds — make that thousands — of imitators who have tried in vain to match their swagger and style.

The concert began with some early Stones' numbers that are rarely heard in concert, including the band's cover of the Lennon-McCartney rocker "I Wanna Be Your Man" and the Stones original "It's All Over Now."

They didn't shy away from their darker numbers, including "Paint It Black" and "Sympathy for the Devil" — Jagger started that one wearing a black, purple-lined faux fur cape that conjured up his late '60s satanic image.

He even cracked a joke about one of the band's low points, telling the audience it was in for a treat: "We're going to play the entire "Satanic Majesty's Request" album now," he said, referring to one of the band's least-loved efforts, a psychedelic travesty that has been largely, mercifully, forgotten.

He didn't make good on his threat.

He also made fun of the sky-high ticket prices, which had exposed the band to some criticism in the London press.

"How are you doing up in the cheap seats," he said, motioning to fans in the upper rows of the cavernous 02 Arena. "Except they're not cheap seats, that's the problem."

But Jagger seemed more mellow than usual, chatting a bit about the good old days and asking if there was anyone in the crowd who had seen them in 1962, when they first took to the stage.

He said 2012 had been a terrific year for Britain and that the Stones nearly missed the boat, playing no role in the celebration of the Queen's Diamond Jubilee, the London Olympics, or the new James Bond film.

"We just got in under the wire," he said. "We feel pretty good."

Agency Investigates Deaths and Injuries Associated With Bed Rails

Thomas Patterson for The New York Times

Gloria Black’s mother died in her bed at a care facility.

In November 2006, when Clara Marshall began suffering from the effects of dementia, her family moved her into the Waterford at Fairway Village, an assisted living home in Vancouver, Wash. The facility offered round-the-clock care for Ms. Marshall, who had wandered away from home several times. Her husband Dan, 80 years old at the time, felt he could no longer care for her alone.

Thomas Patterson for The New York Times

Gloria Black, visiting her mother’s grave in Portland, Ore. She has documented hundreds of deaths associated with bed rails and said families should be informed of their possible risks.

But just five months into her stay, Ms. Marshall, 81, was found dead in her room apparently strangled after getting her neck caught in side rails used to prevent her from rolling out of bed.

After Ms. Marshall’s death, her daughter Gloria Black, who lives in Portland, Ore., began writing to the Consumer Product Safety Commission and the Food and Drug Administration. What she discovered was that both agencies had known for more than a decade about deaths from bed rails but had done little to crack down on the companies that make them. Ms. Black conducted her own research and exchanged letters with local and state officials. Finally, a letter she wrote in 2010 to the federal consumer safety commission helped prompt a review of bed rail deaths.

Ms. Black applauds the decision to study the issue. “But I wish it was done years ago,” she said. “Maybe my mother would still be alive.” Now the government is studying a problem it has known about for years.

Data compiled by the consumer agency from death certificates and hospital emergency room visits from 2003 through May 2012 shows that 150 mostly older adults died after they became trapped in bed rails. Over nearly the same time period, 36,000 mostly older adults — about 4,000 a year — were treated in emergency rooms with bed rail injuries. Officials at the F.D.A. and the commission said the data probably understated the problem since bed rails are not always listed as a cause of death by nursing homes and coroners, or as a cause of injury by emergency room doctors.

Experts who have studied the deaths say they are avoidable. While the F.D.A. issued safety warnings about the devices in 1995, it shied away from requiring manufacturers to put safety labels on them because of industry resistance and because the mood in Congress then was for less regulation. Instead only “voluntary guidelines” were adopted in 2006.

More warnings are needed, experts say, but there is a technical question over which regulator is responsible for some bed rails. Are they medical devices under the purview of the F.D.A., or are they consumer products regulated by the commission?

“This is an entirely preventable problem,” said Dr. Steven Miles, a professor at the Center for Bioethics at the University of Minnesota, who first alerted federal regulators to deaths involving bed rails in 1995. The government at the time declined to recall any bed rails and opted instead for a safety alert to nursing homes and home health care agencies.

Forcing the industry to improve designs and replace older models could have potentially cost bed rail makers and health care facilities hundreds of million of dollars, said Larry Kessler, a former F.D.A. official who headed its medical device office. “Quite frankly, none of the bed rails in use at that time would have passed the suggested design standards in the guidelines if we had made them mandatory,” he said. No analysis has been done to determine how much it would cost the manufacturers to reduce the hazards.

Bed rails are metal bars used on hospital beds and in home care to assist patients in pulling themselves up or helping them out of bed. They can also prevent people from rolling out of bed. But sometimes patients — particularly those suffering from Alzheimer’s — can get confused and trapped between a bed rail and a mattress, which can lead to serious injury or even death.

While the use of the devices by hospitals and nursing homes has declined as professional caregivers have grown aware of the dangers, experts say dozens of older adults continue to die each year as more rails are used in home care and many health care facilities continue to use older rail models.

Since those first warnings in 1995, about 550 bed rail-related deaths have occurred, a review by The New York Times of F.D.A. data, lawsuits, state nursing home inspection reports and interviews, found. Last year alone, the F.D.A. data shows, 27 people died.

As deaths continued after the F.D.A. warning, a working group put together in 1999 and made up of medical device makers, researchers, patient advocates and F.D.A. officials considered requiring bed rail makers to add warning labels.

But the F.D.A. decided against it after manufacturers resisted, citing legal issues. The agency said added cost to small manufacturers and difficulties of getting regulations through layers of government approval, were factors against tougher standards, according to a meeting log of the group in 2000 and interviews.

Playa Vista's parent company is being sold

The parent company of Playa Vista is set to be sold to a Canadian developer that intends to finish building the housing approved for the planned community near Marina del Rey, according to people close to the deal.

Brookfield Homes is buying Playa Capital Co. and gaining command of more than 50 acres of land near the coast. The transaction, valued at more than $250 million, is set to close at the end of the month, according to the individuals, who wished to remain anonymous because the deal isn't wrapped up.

Playa Vista has been under development for more than a decade. The 1,000-acre community already has more than 3,200 residences and 2 million square feet of offices. The land Brookfield is taking over is zoned for an additional 2,000 housing units.

As the new master developer of Playa Vista, Brookfield is expected to sell rights to develop 1,500 apartments to Irvine Apartment Communities, a division of Irvine Co. It is also expected to sell some of the remaining 500 residential sites to Los Angeles developer KB Home.

Developers at work at Playa Vista include Ratkovich Co. and Lincoln Property Co. Ratkovich is turning buildings once occupied by mogul Howard Hughes' aviation company into creative office space for rent, and Lincoln is working on the Runway, a $260-million shopping and apartment complex intended to be the commercial and social heart of Playa Vista.

Representatives of Playa Capital, Brookfield and the Irvine Co. declined to comment. Earlier this month Brookfield Residential Properties raised $222 million through a stock sale, which it used to pay down debt.

Lincoln Property executive David S. Binswanger acknowledged that Playa Capital is on the market.

"Obviously a sales transaction to new, well-qualified and capitalized developers would be nothing but good for the area," he said.

Pierpont Inn & Spa in Ventura is sold

The Pierpont Inn & Spa, a century-old Ventura hotel that once served as a getaway for L.A.'s upper crust, has been sold for $6.5 million.

The 77-room Arts and Crafts-style hotel was built in 1910 by Josephine Pierpont and is the oldest hostelry in Ventura County.

A 1916 story in The Times called it "an inn of the highest class" and praised its views of the Channel Islands.

The hotel at 550 Sanjon Road was purchased from a private investor, said real estate broker Kent R. Williams of Marcus & Millichap. Public records identify the seller as the Ahn Family Trust and the buyer as a limited partnership.

Famous guests of the hotel include Hollywood legends Cecil B. DeMille, Bette Davis, Edward G. Robinson and Charlie Chaplin. Former President George H.W. Bush stayed there with his family when he was in the oil business in the years after World War II.

U.S. architects report growth in October

The nation's architects reported improved business in October, with billings accelerating to their strongest pace of growth since December 2010.

Architectural contracts are a leading indicator of construction activity, with a lag time of about nine months to a year between the awarding of contracts and construction spending.

The American Institute of Architects, the leading trade group for the profession, said its index of "work on the boards" reported by architects was 52.8, up from 51.6 in September. Any score above 50 indicates an increase in billings.

"With three straight monthly gains — and the past two being quite strong — it's beginning to look like demand for design services has turned the corner," chief economist Kermit Baker said.

L.A.'s revamped teacher evaluation system getting mixed grades

Third-grade teacher Kelly Vallianos wanted to find an engaging way for her students to learn about measuring perimeters. One idea — to have students design a restaurant floor plan — was too difficult, she feared.

But with the help of colleagues, she found a way to tailor that fifth-grade idea to her younger students at Dominguez Elementary School, who excitedly sketched out an imaginary pizzeria.

Vallianos credits the Los Angeles Unified School District's new teacher evaluation system for sparking deeper and more collaborative conversations with administrators, who she said gave her ideas to make the lesson work.

The district's new performance reviews have come under fire by United Teachers Los Angeles, which opposes the controversial element of using student test scores as one factor in measuring teacher effectiveness.

But largely lost in the debate is the fact that the system's centerpiece is a new classroom observation process that, despite some drawbacks, is being praised by many as a better way to help teachers improve.

"It's a more reflective, much more well-rounded process," said Vallianos, who has been teaching for 19 years.

Teachers are ranked on a scale on instruction, lesson plans, classroom environment and dozens of other criteria. A highly effective teacher, for instance, will be able to intellectually engage all students and prompt them to lead their own discussion topics. An ineffective teacher will generate all questions and most answers, involving just a handful of students.

During observations, administrators type notes into their laptops and later rate each of 61 skills. Principals and other administrators conducting the observations must pass a test to ensure they are fairly and accurately scoring instructors. Conferences with teachers before and after the classroom visits are required.

The method is meant to make observations more useful, uniform and objective, using evidence rather than opinions. But it's an elaborate process and has provoked widespread criticism that it takes too long for principals who are already overwhelmed with increasing workloads. And those who can't type well take even longer, administrators say.

"The technology is creating great difficulty and frustration," said Judith Perez, president of the Associated Administrators of Los Angeles. "It feels like an immense amount of pressure on people without alleviating their workload."

Teachers union President Warren Fletcher agrees that a better system is needed; UTLA has designed its own. He said "the jury is still out" on the district's observation process but added that it shares some common elements with the union's proposal.

The new system also includes evidence of student achievement — which could be in the form of test scores — feedback from students and parents, and the teacher's contributions to the school community.

The new observations were tested last year on a voluntary basis with about 450 teachers and 320 administrators; this year, every principal and one volunteer teacher at each of the district's 1,200 schools are expected to be trained.

Officials have not yet announced when the system will be used for every teacher — or when the ratings will begin to count for decisions on layoffs, tenure or pay. But in a video shown at the training sessions, L.A. Supt. John Deasy made the stakes clear.

"We have perhaps no greater responsibility than assuring that every student in this district is taught by an effective teacher in a school led by an effective leader," he said.

Many educators agree that the current evaluation system — known as Stull for the state law that created it — doesn't promote that goal of top-notch teachers for every student. Criticized as a perfunctory checklist of expectations that doesn't help teachers improve, the system awarded 99.3% of L.A. Unified teachers the highest rating in 2009-10 — even though only 45% of district students that year performed at grade level for reading and 56% were proficient in math.

The new system has given teachers like Lisa Thorne a boost. Thorne, a math teacher at Hamilton High School, said the new process is "unwieldy" but far more helpful in homing in on her strengths and weaknesses.

After the self-evaluation part of the process, Thorne chose to focus on improving her work with small groups of students, prompting her to try such techniques as using a three-dimensional pegboard to teach geometry. And she started a new computer-based class to help struggling ninth-graders master algebra. Administrators had seen her use the techniques with older students during a class visit and were impressed enough to give her the green light, she said.

"I would definitely say the new system is an improvement, because it's more specific about what they're looking for," Thorne said. "It helps to get the conversation going with administrators."

Eduardo Solorzano, principal of San Fernando Middle School, agrees. In particular, he said, the focus on careful note-taking has given him specific examples to use in helping teachers improve.

'Gangnam Style' most watched YouTube video ever

SEOUL, South Korea (AP) — South Korean rapper PSY's "Gangnam Style" has become YouTube's most viewed video of all time.

YouTube says in a posting on its Trends blog that "Gangnam Style" had been viewed 805 million times as of Saturday afternoon, surpassing Justin Bieber's "Baby," which has had 803 million views.

The blog says the "velocity of popularity for PSY's outlandish video is unprecedented."

PSY's video featuring his horse-riding dance was posted on YouTube in July, while "Baby" was uploaded in February 2010.

PSY's video has become a global sensation, with many people around the world mimicking his "Gangnam Style" dance. In their October meeting, U.N. Secretary-General Ban Ki-moon, a South Korean, joked that he had to relinquish his title as "the most famous Korean," and tried a few of PSY's dance moves.

Toyota on track to become world's bestselling automaker again

Toyota Motor Corp. appears poised to regain its position as the world's largest automaker, a remarkable turnaround after years of safety recalls, huge federal fines and the Japanese earthquake last year.

In short order, surging sales have put that all in the rearview mirror.

Toyota is likely to sell 9.7 million vehicles this year, surpassing second-place General Motors Co. by more than 1 million vehicles and setting a record for annual auto sales. That's generating huge profits, with earnings tripling in the latest quarter to $3.2 billion and sales surging almost 20% compared with a year earlier.

The U.S. — where Toyota's reputation suffered most through the recalls — is now a cash cow. Through the first 10 months of the year, the Japanese automaker sold more than 1.7 million cars and trucks in the country, a 30% gain and more than double the industry growth rate.

"Toyota has done some smart things," said Rebecca Lindland, an analyst with IHS Automotive. "They have concentrated a lot of time and effort on the U.S., which is incredibly important because they make so much money here."

The Japanese automaker has launched 11 new or completely redesigned models in the U.S. in the last year, including new station wagon and commuter versions of its popular Prius hybrids. On Wednesday, the first day of the Los Angeles Auto Show, it will launch a new-generation RAV4 sport utility vehicle. The current model is an aging vehicle facing stiff competition from newly redesigned offerings such as Ford Motor Co.'s Escape and Honda Motor Co.'s CR-V.

Toyota has ramped up its factories in the U.S., opening a Corolla plant in Mississippi and expanding pickup truck manufacturing in Texas. And at the urging of Chief Executive and founding-family member Akio Toyoda, the automaker is looking to inject some panache into its historically bland styling, especially for its Lexus luxury division.

Toyota now accounts for 14.4% of the U.S. auto market, up from 12.6% during the first 10 months of 2011. In retail — not including rental and fleet sales — the Toyota brand is the biggest in the U.S., outselling GM's Chevrolet.

Lynne Thomas, a Santa Monica resident who works in the restaurant industry, bought a Toyota Prius C hybrid in October after considering other fuel-efficient vehicles including the Smart fortwo, Fiat 500 and Volkswagen Jetta.

"I love the mileage. I'm getting more than 50 mpg," Thomas said. "It fits my lifestyle completely. It is easy to park in this crazy city. I can put my bike in the back and drive somewhere and do an amazing bike ride. It works really well in stop-and-go traffic."

The company is expanding its factory network in the U.S. as part of a strategy to manufacture in regional markets and blunt the profit-eating consequences of the Japanese yen's strong exchange rate with the dollar. It has put $1.4 billion into U.S. factories and equipment in the last year, adding more than 2,700 jobs, on top of the 1,300 positions created in the U.S. the previous year.

The expansion comes after Toyota's controversial decision to close the New United Motor Manufacturing Inc. plant in Fremont, Calif., displacing nearly 5,000 workers in early 2010. Toyota shut the plant after GM, as part of its bankruptcy reorganization, pulled out of joint manufacturing there.

Toyota also is shipping more U.S.-built vehicles abroad. In the first 10 months of this year, it exported 74,000 U.S.-built cars to Canada and Mexico and 29,000 to overseas markets. It is sending Kentucky-built Camrys to South Korea and Indiana-built Sequoias to Saudi Arabia. Exports of U.S.-built Toyotas are on track to rise more than 50% this year.

Just three years ago, Toyota was the second-largest auto seller in America, with 17% of the market, and was closing in on a crippled GM, which was struggling with the stigma of bankruptcy and a federal bailout. But Toyota was derailed in a series of embarrassing recalls. In one high-profile accident, an improperly positioned floor mat in a sedan from Toyota's Lexus luxury division may have trapped the accelerator — causing the car to race down California Highway 125 near San Diego at more than 100 mph. The car crashed and burned, killing off-duty California Highway Patrol Officer Mark Saylor and three members of his family.

That crash led to a safety investigation and recall of 3.8 million Toyota and Lexus vehicles to fix the floor mat problem. After a Los Angeles Times series on unintended sudden acceleration, Toyota issued millions more recall notices to fix sticking gas pedals and other issues. Then, two years ago, Toyota paid record federal fines of nearly $50 million for failing to promptly inform regulators of defects and for delaying recalls. At one point it had to halt much of its production of new cars in the U.S. to fix recalled vehicles.

Just as the automaker started to recover, it was hobbled by last year's earthquake and tsunami in Japan, which upended Toyota's manufacturing even on American soil. Toyota's share of U.S. auto sales slid to 12.9%, well below GM's and Ford's.

Several factors have helped Toyota survive the recalls and disaster-related production shutdowns, said James E. Lentz, CEO of Toyota Motor Sales, the automaker's U.S. marketing arm.

First, there was "the loyalty of our consumers as we went from the financial crisis to the recalls to the tsunami," he said. "They stayed with us for the entire time."

Lentz is thankful for customers such as Evan Rabinowitz of Sherman Oaks, who bought a Camry sedan in August.

"I didn't look at anything else because I never had an issue with my 2008 Camry. Going back to Toyota was a no-brainer," said Rabinowitz, who owns a fabric business. He said his previous Toyota was recalled twice to fix pedal issues, but that work was done quickly and well and didn't dissuade him from purchasing another Camry.

Dave Roberts brings diversity to the San Diego County supervisors

DEL MAR — In January, when he joins the San Diego County Board of Supervisors, Dave Roberts will be the only Democrat among four Republicans, the first Democrat on the board in more than two decades.

He will also be the first new supervisor in 18 years. And he will be the only one who is not a graduate of San Diego State. He has three degrees from American University in Washington, D.C.

He's also gay and married to a retired Air Force master sergeant. The two are adoptive parents to five former foster children, ages 4 to 17, who call them Daddy Dave and Daddy Wally.

With Roberts' election to a district representing a portion of San Diego and several seaside communities north of the city, diversity has arrived for the Board of Supervisors, long one of the region's most homogenous governing bodies.

"I'm going to bring some unique characteristics," Roberts, 51, said with a laugh during a family outing on the beach here.

Roberts hopes to concentrate on the same issues he focused on while serving on the Solana Beach City Council, where he is currently deputy mayor: regional fire protection, expansion of the San Dieguito River Park and "sensible" growth.

Roberts is a Democrat in the style of Republican-leaning northern San Diego County: fiscally conservative. He worked as a budget analyst for the Department of Defense and as a corporate vice president for the La Jolla-based defense contractor SAIC. He was a Republican until some in the GOP took exception to a gay man working in the Pentagon.

"The Republicans wanted me to be fired," Roberts said. "That's when I changed political parties."

Some of his first experience in government came from working as a staffer to Sen. Lowell Weicker, a Republican from Connecticut. "I learned from working for Sen. Weicker that you can make change if you're in the right place," Roberts said.

In 2009, Democratic party officials encouraged Roberts to seek the party's nomination to face incumbent Brian Bilbray (R-Carlsbad) in the 50th Congressional District.

On the verge of declaring his candidacy, Roberts was alerted by social workers about two children who needed a "forever" home. He decided that the adoption process took precedence over his political career.

Now there are five children in the two-story home in Solana Beach once owned by singer Patti Page: Robert, 17; Alex, 12; Julian, 8; Joe, 5; and Natalee, 4. Three of the children have taken the last name Roberts, and two took his spouse's last name, Oliver.

"We don't like double names," Roberts said.

Roberts and Wally Oliver, 55, have been together for 14 years. They had a commitment ceremony in 1998 and married in July 2008 in the brief period when county clerks in California were allowed to issue same-sex marriage licenses.

The family may soon expand.

"Wally would like a baby," Roberts said. "We're not Jewish, but we believe in the Jewish proverb: 'If you can save one soul, you can save the world.'"

During his race against a Republican opponent, Roberts was endorsed by the retiring incumbent, Pam Slater-Price. He has also begun discussions with Supervisor Dianne Jacob, possibly the most fiscally conservative member of the board.

He also looks forward to working with Supervisor Bill Horn, an ex-Marine who supported Proposition 8, the measure to ban same-sex marriage, and has said he opposes gays in the military. "He says things from time to time that remind me of my father," Roberts said.

For all of their fiscal conservatism, the supervisors have not dabbled much in social issues in a way that might satisfy some elements in the GOP. The board took no position on Proposition 8. Health clinics in gay neighborhoods and AIDS prevention programs are funded without controversy.

Roberts may be different in another respect from his colleagues: He will not be assigning a staff member to send out his Twitter messages. He sends out his own tweets — lots of them, on topics political and personal.

Last week, among many tweets, was one announcing that he has hired his predecessor's chief-of-staff, praising him for his "broad experience, management style and network of contacts."

And the next tweet: "Took the kids out for frozen yogurt at Seaside Yogurt in Del Mar for a treat."

Secret message found with carrier pigeon may never be deciphered

British man finds carrier pigeon skeleton in his fireplace with unbreakable secret code (Reuters)

Before military forces had secure cell phones and satellite communications, they used carrier pigeons. The highly trained birds delivered sensitive information from one location to another during  World War II. Often, the birds found the intended recipient. But not always.

A dead pigeon was recently discovered inside a chimney in Surrey, England. There for roughly 70 years, the bird had a curious canister attached to its leg. Inside was a coded message that has stumped the experts.

The code features a series of 27 groups of five letters. According to Reuters, nobody from Britain’s Government Communications Headquarters has been able to decipher it. The message was sent by a Sgt. W. Scott to someone or something identified as “Xo2.”

A spokesperson remarked, “Although it is disappointing that we cannot yet read the message brought back by a brave carrier pigeon, it is a tribute to the skills of the wartime code-makers that, despite working under severe pressure, they devised a code that was indecipherable both then and now.”

The bird was discovered by a homeowner doing renovations earlier this month. In an interview with Reuters, David Martin remarked that bits of birds kept falling from the chimney. Eventually, Margin saw the red canister and speculated that it might contain a secret message. And it seems as if the message will always be secret.

Carrier pigeons played a vital role in wars due to their incredible homing skills. All told, U.K. forces used about 250,000 of the birds during World War II.

Marc Anthony comes to aid of Dominican orphanage

SANTO DOMINGO, Dominican Republic (AP) — Singer Marc Anthony is coming to the aid of an orphanage in the Dominican Republic.

A foundation run by Anthony with music and sports producer Henry Cardenas plans to build a new residence hall, classrooms and a baseball field for the Children of Christ orphanage in the eastern city of La Romana. Anthony attended the groundbreaking ceremony Friday with his model girlfriend Shannon de Lima.

Children of Christ Foundation Director Sonia Hane said Anthony visited the orphanage previously and decided to help. His Maestro Cares Foundation raised $200,000 for the expansion on land donated by a sugar company. The orphanage was founded in 1996 for children who were abused or abandoned or whose parents were unable to care for them.

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.
