Peering into neural networks

New technique helps elucidate the inner workings of neural networks trained on visual data by Larry Hardesty, MIT News Office CAMBRIDGE, Mass. — Neural networks, which learn to perform computational tasks by analyzing large sets of training data, are responsible for today’s best-performing artificial intelligence systems,

Scientists produce dialysis membrane made from graphene

Material can filter nanometer-sized molecules at 10 to 100 times the rate of commercial membranes. by Jennifer Chu, MIT News Office CAMBRIDGE, Mass. — Dialysis, in the most general sense, is the process by which molecules filter out of one solution, by diffusing through a membrane,

New technique makes brain scans better

Boosting quality of patient MRIs could enable large-scale studies of stroke outcome by Anne Trafton, MIT News Office CAMBRIDGE, MA – People who suffer a stroke often undergo a brain scan at the hospital, allowing doctors to determine the location and extent of the damage.

Shrinking data for surgical training

Technique that reduces video files to one-tenth their initial size enables speedy analysis of laparoscopic procedures by Larry Hardesty, MIT News Office CAMBRIDGE, Mass. — Laparoscopy is a surgical technique in which a fiber-optic camera is inserted into a patient’s abdominal cavity to provide a video

Search for life: NASA introduces 10 new Earth-size planets

“Of roughly 50 near-Earth size habitable zone candidates detected by Kepler, more than 30 have been verified,” NASA said Here’s good news from NASA. The US space agency revealed Monday that there’re possibilities of life in 10 new planets which have the size of earth.

Learning with light: New system allows optical “deep learning”

Neural networks could be implemented more quickly using new photonic technology by David L. Chandler, MIT News Office CAMBRIDGE, Mass. — “Deep Learning” computer systems, based on artificial neural networks that mimic the way the brain learns from an accumulation of examples, have become a

Socioeconomic background linked to reading improvement

Dyslexic children from lower-income families benefit more from summer reading intervention by Anne Trafton, MIT News CAMBRDIGE, Mass. — About 20 percent of children in the United States have difficulty learning to read, and educators have devised a variety of interventions to try to help

Giving robots a sense of touch

GelSight technology lets robots gauge objects’ hardness and manipulate small tools. by Larry Hardesty, MIT News Office CAMBRIDGE, Mass. — Eight years ago, Ted Adelson’s research group at MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL) unveiled a new sensor technology, called GelSight, that uses physical
