Algorithm analyzes head movements to measure heart rate

http://web.mit.edu/newsoffice/2013/seeing-the-human-pulse-0620.html MIT researchers have developed an algorithm that gauges heart rate by measuring tiny head movements in video data.  A subject’s heart rate was consistently measured within a few beats per minute when compared to results from electrocardiograms. The algorithm was also able to provide estimates of time intervals between beats, which can be used to identify […]

Low cost GPU based neural network simulates the brain

http://stanford.edu/~acoates/papers/CoatesHuvalWangWuNgCatanzaro_icml2013.pdf In a new paper, Stanford’s Andrew Ng describes how to use graphics microprocessors to build a $20,000 computerized brain that is similar to the cat-detector he developed with Google last year for $1M. To test his hypothesis about GPU-driven Deep Learning, he also built a larger version of the platform for $100,000.  It utilized […]

Nerve and muscle interfaces for prosthetic control

http://www.darpa.mil/NewsEvents/Releases/2013/05/30.aspx DARPA continues to build technology with academic partners to enable amputees to control prosthetic limbs with their minds.  Examples follow: Researchers at the Rehabilitation Institute of Chicago demonstrated a type of peripheral interface called targeted muscle re-innervation (TMR). By rewiring nerves from amputated limbs, new interfaces allow for prosthetic control with existing muscles. Researchers […]

Cornell robots anticipate human actions

http://news.cornell.edu/stories/2013/04/think-ahead-robots-anticipate-human-actions Cornell University researchers have programmed a PR-2 robot to not only carry out everyday tasks, but to anticipate human behavior and adjust its actions. From a database of 120 3-D videos of people performing common household activities, the robot has been trained to identify human activities by tracking the movements of the body – reduced […]

Watson’s health care capabilities described to lawmakers

http://www.washingtonpost.com/blogs/innovations/wp/2013/05/17/watson-goes-to-washington-ibm-shows-off-latest-health-care-work-to-lawmakers/ On Capitol Hill, IBM representatives described the supercomputer’s new health-care related features, including the ability to ingest patients’ medical information and synthesize thousands of medical journals and other reference materials along with patient preferences to suggest treatment options. The Watson team has collaborated with the Memorial Sloan-Kettering Cancer Center and insurer Well Point to teach […]

Quantum computing AI lab from Google, NASA and USRA

http://googleresearch.blogspot.ca/2013/05/launching-quantum-artificial.html Google, NASA and the Universities Space Research Association will put a 512 qubit machine from D-Wave at the disposal of researchers around the globe.  The USRA will invite teams of scientists and engineers to share time on the unique supercomputer. The goal is to study how quantum computing might be leveraged to advance machine learning.
