Scientist Develop Anti-Faking PC

Scientists have developed a computer system with sophisticated pattern recognition abilities that performed more impressively than humans in differentiating between people experiencing genuine pain and people who were just pretending.

In a study published in the journal Current Biology, human subjects did no better than chance – about 50 percent – in correctly judging if a person was feigning pain after seeing videos in which some people were and some were not.

The computer was right 85 percent of the time. Why? The researchers say its pattern-recognition abilities successfully spotted distinctive aspects of facial expressions, particularly involving mouth movements, that people generally missed.

“We all know that computers are good at logic processes and they’ve long out-performed humans on things like playing chess,” said Marian Bartlett of the Institute for Neural Computation at the University of California-San Diego, one of the researchers.

“But in perceptual processes, computers lag far behind humans and have a lot of trouble with perceptual processes that humans tend to find easy, including speech recognition and visual recognition. Here’s an example of a perceptual process that the computer is able to do better than human observers,” Bartlett said in a telephone interview.

For the experiment, 25 volunteers each recorded two videos.

In the first, each of the volunteers immersed an arm in lukewarm water for a minute and were told to try to fool an expert into thinking they were in pain. In the second, the volunteers immersed an arm in a bucket of frigid ice water for a minute, a genuinely painful experience, and were given no instructions on what to do with their facial expressions.

The researchers asked 170 other volunteers to assess which people were in real discomfort and which were faking it.

After they registered a 50 percent accuracy rate, which is no better than a coin flip, the researchers gave the volunteers training in recognizing when someone was faking pain. Even after this, the volunteers managed an accuracy rate of only 55 percent.

The computer’s vision system included a video camera that took images of a person’s facial expressions and decoded them. The computer had been programmed to recognize that one kind of facial movement combinations suggested true pain and another kind suggested faked pain.

AMD Buys Mobile Patents

China’s Lenovo is acquiring patents related to 3G and 4G technologies from U.S.-based Unwired Planet for $100 million, as the company sets about expanding with its proposed Motorola Mobility acquisition.

The 21 patent families that Lenovo is purchasing from Unwired Planet will help the Chinese company grow its smartphone and mobile business in new markets, it said Thursday.

In addition, Unwired Planet is licensing its patent portfolio to Lenovo for an unspecified number of years. The Nevada-based company develops mobile technologies in use by carriers including AT&T and Sprint. After its deal with Lenovo closes, Unwired Planet said it will have about 2,500 issued and pending international patents in its portfolio.

Although Lenovo is best known as a PC maker, the company is aiming to becoming a major vendor of mobile phones. Already, in its home market of China, Lenovo ranks as one of the biggest smartphone vendors, and has dozens of different models on the local market.

Lenovo’s mobile phone business is set to grow even larger. In January, the company announced it planned to buy Motorola Mobility from Google for $2.9 billion.

With the proposed acquisition, Lenovo’s handset business will get a foothold in the North American market. The company plans to keep the Motorola business intact, and even use the business to sell phones in its home market of China.

The Motorola deal will also help Lenovo shield itself from patent-related lawsuits that have been used to try to stymie the businesses of other handset makers. By buying Motorola, Lenovo will take ownership of more than 2,000 patent assets and also gain access to Google’s own patent portfolio.

Lenovo’s deal with Unwired Planet is expected to close in 30 days.

AMD To Focus On China

Advanced Micro Devices has relocated its desktop chip business operations from the U.S. to the growing market of China, adding to its research lab and testing plant there.

The desktop market in China is growing at a fast pace and its shipments of desktops and laptops are equal in ratio, said Michael Silverman, an AMD spokesman, in an email. “The desktop market in China remains strong,” Silverman said.

The move of AMD’s desktop operations was first reported by technology news publication Digitimes, but the chip maker confirmed the news.

The company is also developing tailored products for users in China, Silverman said.

AMD’s move of desktop operations to China brings them closer to key customers such as Lenovo, said Dean McCarron, principal analyst at Mercury Research.

“Not that they don’t have their sales in the U.S.,” but a significant number of those PCs are made in China and then shipped internationally, McCarron said.

AMD is the world’s second-largest x86 processor maker behind Intel. Many PC makers like HP and Dell get products made in China.

Being in China also solves some desktop supply chain issues because it moves AMD closer to motherboard suppliers like Asustek and MSI, which are based in Taiwan, but get parts made in China. Chips will be shipped to customers faster and at a lower cost, which would reduce the time it takes for PCs to come to market, McCarron said.

AMD already has a plant in Suzhou, which Silverman said “represents half of our global back-end testing capacity.” AMD’s largest research and development center outside the U.S. is in Shanghai.

Some recent products released by the company have been targeted at developing countries. AMD recently starting shipping Sempron and Athlon desktop chips for the Asia-Pacific and Latin America markets, and those chips go into systems priced between $60 and $399. AMD is targeting the chips at users that typically build systems at home and shop for processors, memory and storage. The chips — built on the Jaguar microarchitecture — go into AMD’s new AM1 socket, which will be on motherboards and is designed for users to easily upgrade processors.

China is also big in gaming PCs, and remains a key market for AMD’s desktop chips, said Nathan Brookwood, principal analyst at Insight 64. “White box integrator’s play a big role in China,” he said.

Will Chrome’s API Work?

Google has targeted web browser settings hijacking in its latest update to Chrome for Windows.

On the Chromium blog, Google engineering director Erik Kay announced an extension settings API designed to ensure that users have notice and control over any settings changes made to their web browsers.

As a result, the only way extensions will be able to make changes to browser settings such as the default search engine and start page will be through this API.

Bargain hungry consumers are often unaware that freeware programs often bundle add-on programs for which developers receive payment but can create irritating, rather than malicious, changes to user settings.

Although there is usually consent sought at installation, quite often it is ignored or not understood, and the people who miss the warnings are generally the same ones who find it hard to change the settings back.

Kay said that the API is available in the Chromium developer channel, with a rollout to the stable channel set for May.

The Chromium stable channel has been updated to version 33.0.1750.149. The main change is an update to the embedded Flash Player for Windows, which is now version 12.0.0.77.

There are seven new security fixes, most of which were user submitted via the open source Fast Memory Detector Address Sanitizer.

Although the user community and Chrome team continue to proactively protect the Chromium project, third party extensions can still cause problems, with several already having been removed from the Chrome Store this year.

Will Google Use Intel Inside?

It seems that Intel has elbowed its way under the bonnet of the high profile Nexus 8 tablet. Word on the street is that the Moorefield chip which is said to make a top speed of around 2.33 GHz, when the wind is behind it, has kicked Qualcomm’s tried and tested Snapdragon chip out of the Nexus range.

The move would give the Nexus 8, some good GPU power thanks to the PowerVR G6430 graphic engine. Google may unveil the actual tablet during the Google I/O event as well as the next big upgrade to the Android software dubbed lollipop. Still it is starting to look like Intel may really become a force to be reckoned with in mobile after all.

However, we should point out that Nexus 8 CPU rumors are nothing new. There was talk of Intel, Qualcomm and even Nvidia over the past couple of months – but we are still not entirely certain what’s under the bonnet.

nVidia Outs CUDA 6

Nvidia has made the latest GPU programming language CUDA 6 Release Candidate available for developers to download for free.

The release arrives with several new features and improvements to make parallel programming “better, faster and easier” for developers creating next generation scientific, engineering, enterprise and other applications.

Nvidia has aggressively promoted its CUDA programming language as a way for developers to exploit the floating point performance of its GPUs. Available now, the CUDA 6 Release Candidate brings a major new update in unified memory access, which lets CUDA applications access CPU and GPU memory without the need to manually copy data from one to the other.

“This is a major time saver that simplifies the programming process, and makes it easier for programmers to add GPU acceleration in a wider range of applications,” Nvidia said in a blog post on Thursday.

There’s also the addition of “drop-in libraries”, which Nvidia said will accelerate applications by up to eight times.

“The new drop-in libraries can automatically accelerate your BLAS and FFTW calculations by simply replacing the existing CPU-only BLAS or FFTW library with the new, GPU-accelerated equivalent,” the chip designer added.

Multi-GPU Scaling has also been added to the CUDA 6 programming language, introducing re-designed BLAS and FFT GPU libraries that automatically scale performance across up to eight GPUs in a single node. Nvidia said this provides over nine teraflops of double-precision performance per node, supporting larger workloads of up to 512GB in size, more than it’s supported before.

“In addition to the new features, the CUDA 6 platform offers a full suite of programming tools, GPU-accelerated math libraries, documentation and programming guides,” Nvidia said.

The previous CUDA 5.5 Release Candidate was issued last June, and added support for ARM based processors.

Aside from ARM support, Nvidia also improved Hyper-Q support in CUDA 5.5, which allowed developers to use MPI workload prioritisation. The firm also touted improved performance analysis and improved performance for cross-compilation on x86 processors.

Is AMD Worried?

AMD’s Mantle has been a hot topic for quite some time and despite its delayed birth, it has finally came delivered performance in Battlefield 4. Microsoft is not sleeping it has its own answer to Mantle that we mentioned here.

Oddly enough we heard some industry people calling it DirectX 12 or DirectX Next but it looks like Microsoft is getting ready to finally update the next generation DirectX. From what we heard the next generation DirectX will fix some of the driver overhead problems that were addressed by Mantle, which is a good thing for the whole industry and of course gamers.

AMD got back to us officially stating that “AMD would like you to know that it supports and celebrates a direction for game development that is aligned with AMD’s vision of lower-level, ‘closer to the metal’ graphics APIs for PC gaming. While industry experts expect this to take some time, developers can immediately leverage efficient API design using Mantle. “

AMD also told us that we can expect some information about this at the Game Developers Conference that starts on March 17th, or in less than two weeks from now.

We have a feeling that Microsoft is finally ready to talk about DirectX Next, DirectX 11.X, DirectX 12 or whatever they end up calling it, and we would not be surprised to see Nvidia 20nm Maxwell chips to support this API, as well as future GPUs from AMD, possibly again 20nm parts.

What Do Smaller Controllers Mean?

If you want a wearable Internet of Things, the electronics have to be as tiny and as energy efficient as possible. That’s why a new microcontroller by Freescale Semiconductor is noteworthy.

The company has produced the Kinetis KLO3 MCU, a 32-bit ARM system that is 15% smaller than its previous iteration but with a 10% power improvement.

Internet of Things is a buzzword for the trend toward network-connected sensors incorporated into devices that in the past were standalone appliances. These devices use sensors to capture things like temperatures in thermostats, pressure, accelerometers, gyroscopes and other types of MEMS sensors. A microcontroller unit gives intelligence and limited computational capability to these devices, but is not a general purpose processor. One of the roles of the microcontroller is to connect the data with more sophisticated computational power.

The Kinetis KLO3 runs a lightweight embedded operating system to connect the data to other devices, such as an app that uses a more general purpose processor.

Kathleen Jachimiak, product launch manager at Freescale, said the new microcontroller will “enable further miniaturization” in connected devices. This MCU is capable of having up to 32 KB of flash memory and 2 KB of RAM.

Consumers want devices that are light, small and smart. They also want to be able to store their information and send it to an application that’s either on a phone or a PC, Jachimiak said.

This microcontroller, at 1.6 x 2.0 mm, is smaller than the dimple on a golf ball, and uses a relatively new process in its manufacturing, called wafer level chip scale packaging. The process involves building the integrated package while the die is still part of a wafer. It’s a more efficient process and produces the smallest possible package, for a given die size.

Samsung Joins OpenPower

Samsung has joined Google, Mellanox, Nvidia and other tech companies as part of IBM’s OpenPower Consortium. The OpenPower Consortium is working toward giving developers access to an expanded and open set of server technologies to improve data centre hardware using chip designs based on the IBM Power architecture.

Last summer, IBM announced the formation of the consortium, following its decision to license the Power architecture. The OpenPower Foundation, the actual entity behind the consortium, opened up the Power architecture technology, including specs, firmware and software under a license. Firmware is offered as open source. Originally, OpenPower was the brand of a range of System p servers from IBM that utilized the Power5 CPU. Samsung’s products currently utilize both x86 and ARM-based processors.

The intention of the consortium is to develop advanced servers, networking, storage and GPU-acceleration technology for new products. The four priority technical areas for development are system software, application software, open server development platform and hardware architecture. Along with its announcement of Samsung’s membership, the organization said that Gordon MacKean, Google’s engineering director of the platforms group, will now become chairman of the group. Nvidia has said it will use its graphics processors on Power-based hardware, and Tyan will be releasing a Power-based server, the first one outside IBM.

Did Intel Kill Bay Trail?

Intel has decided that some of its budget Bay Trail parts have been out evolved and flung them into a tar pit. According to CPU World the parts first appeared in September. Intel released budget Bay Trail systems on a chip for mobile and desktop markets, under Celeron and Pentium brands.

They were manufactured on 22nm technology, and featured such enhancements as greater number of CPU cores, higher clock speeds, beefed up graphics unit, not to mention an out-of-order microarchitecture, that improved per-clock CPU performance by up to 30 per cent faster compared to their predecessors. With this performance goodness it is a little surprising the Intel has decided that all the all Bay Trail SoCs will be discontinued in a matter of a few months. Details of the planned discontinuation were published this week by Intel in several Product Change Notification documents.

The Desktop Pentium J2850, along with mobile Celeron N2810 and Pentium N3510 are already End of Lifed and its last orders will be in two weeks, on February 11. The chips will ship until April 25, 2014. Also retired are mobile Celeron N2806, N2815, N2820, N2920, and Pentium N3520. Their EOL date is April 11, 2014, and they will ship until May 30, 2014. On August 22, 2014, Intel is going to discontinue Celeron J1750, J1850, N2805 and N2910. The “J” models are desktop processors, and the “N” are mobile ones. There is no word on Z-series Bay Trail-T parts, none appear to be EOL’d at this  time.

Furthermore, on the same date Intel will retire Core i7-3940XM Extreme Edition, and boxed and tray versions of Core i7-3840QM and i7-3740QM CPUs. The last shipment date for the Celerons and Core i7s is February 6, 2015.
