Parallelizing common algorithms

January 30, 2015 8:28 am | by Larry Hardesty, MIT News Office | News | Comments

Every undergraduate computer science major takes a course on data structures, which describes different ways of organizing data in a computer’s memory. Every data structure has its own advantages: Some are good for fast retrieval, some for efficient search, some for quick insertions and deletions and so on. Today, hardware manufacturers are making computer chips faster by giving them more cores, or processing units.

Optimizing optimization algorithms

January 21, 2015 9:36 am | by Larry Hardesty, MIT News Office | News | Comments

Optimization algorithms are everywhere in engineering. Among other things, they’re used to evaluate design tradeoffs, to assess control systems and to find patterns in data. One way to solve a difficult optimization problem is to first reduce it to a related but much simpler problem, then gradually add complexity back in, solving each new problem in turn and using its solution as a guide to solving the next one.

Vision system for household robots

January 12, 2015 7:36 am | by Larry Hardesty, MIT News Office | News | Comments

For household robots ever to be practical, they’ll need to be able to recognize the objects they’re supposed to manipulate. But while object recognition is a highly studied topic in artificial intelligence, even the best object detectors still fail much of the time. Researchers at MIT believe that household robots should take advantage of their mobility and their relatively static environments to make object recognition easier.

Baby steps toward molecular robots

December 11, 2014 8:32 am | News | Comments

A walking molecule, so small that it cannot be observed directly with a microscope, has been recorded taking its first nanometer-sized steps. It's the first time that anyone has shown in real time that such a tiny object – termed a "small molecule walker" – has taken a series of steps.

‘Electronic skin’ detects pressure from different directions

December 10, 2014 2:12 pm | by American Chemical Society | News | Comments

For the first time, scientists report the development of a stretchable “electronic skin” closely modeled after our own that can detect not just pressure, but also what direction it’s coming from.                

Computers that teach by example

December 8, 2014 8:49 am | by Larry Hardesty, MIT News Office | News | Comments

Computers are good at identifying patterns in huge data sets. Humans, by contrast, are good at inferring patterns from just a few examples. In a recent paper, Massachusetts Institute of Technology researchers present a new system that bridges these two ways of processing information, so that humans and computers can collaborate to make better decisions.

Artificial intelligence magic tricks

November 17, 2014 8:46 am | by Queen Mary Univ. of London | Videos | Comments

Researchers from the Queen Mary Univ. of London gave a computer program the outline of how a magic jigsaw puzzle and a mind-reading card trick work, as well the results of experiments into how humans understand magic tricks, and the system created completely new variants on those tricks which can be delivered by a magician.

Harnessing error-prone chips

October 30, 2014 7:40 am | by Larry Hardesty, MIT News Office | News | Comments

As transistors get smaller, they also grow less reliable. Increasing their operating voltage can help, but that means a corresponding increase in power consumption. With information technology consuming a steadily growing fraction of the world’s energy supplies, some researchers and hardware manufacturers are exploring the possibility of simply letting chips botch the occasional computation.

Projecting a robot’s intentions

October 29, 2014 1:27 pm | by Jennifer Chu, MIT | Videos | Comments

Inside Massachusetts Institute of Technology’s Building 41, a small, Roomba-like robot is trying to decided where to go. As the robot considers its options, its “thoughts” are projected on the ground in the form of different colored dots and lines. This new visualization system, called “measurable virtual reality”, combines projectors with motion-capture technology and animation software to project a robot’s intentions in real time.

Underwater robot for port security

September 26, 2014 7:42 am | by Larry Hardesty, MIT News Office | News | Comments

Massachusetts Institute of Technology researchers unveiled an oval-shaped submersible robot, a little smaller than a football, with a flattened panel on one side that can slide along an underwater surface to perform ultrasound scans. Originally designed to look for cracks in nuclear reactors’ water tanks, the robot could also inspect ships for the false hulls and propeller shafts that smugglers frequently use to hide contraband.

Video games could dramatically streamline education research

September 19, 2014 9:12 am | by C. Brandon Chapman, Washington State Univ. | News | Comments

Washington State Univ. professor Rich Lamb has figured out a dramatically easier and more cost-effective way to do research on science curriculum in the classroom, and it could include playing video games. Called “computational modeling,” it involves a computer “learning” student behavior and then “thinking” as students would. Lamb, who teaches science education, says the process could revolutionize the way educational research is done.

Where to grab space debris

September 10, 2014 10:10 am | by Larry Hardesty, MIT News Office | News | Comments

Objects in space tend to spin—and spin in a way that’s totally different from the way they spin on earth. Understanding how objects are spinning, where their centers of mass are, and how their mass is distributed is crucial to any number of actual or potential space missions, from cleaning up debris in the geosynchronous orbit favored by communications satellites to landing a demolition crew on a comet.

A new foundation for mathematics

September 3, 2014 12:57 pm | by Florian Meyer, ETH Zurich | News | Comments

Proofs are the key method of mathematics. Until now, it has mainly been humans who have verified whether proofs are correct. This could change, says Russian mathematician Vladimir Voevodsky, who points to evidence that, in the near future, computers rather than humans could reliably verify whether a mathematical proof is correct.

Robots unlikely to take big bites out of employment, expert says

September 2, 2014 11:59 am | by Steve Talley, Purdue Univ. | News | Comments

Advances in artificial intelligence and robotics mean that machines will soon be able to do many of the tasks of today's workers. But David Hummels, a professor of economics at Purdue Univ., says humans still have a unique advantage that machines may never be able to emulate: our ability to respond to other humans.

Algorithm gives credit where credit is due

August 18, 2014 8:29 am | by Joe O'Connell, Staff Writer, Northeastern Univ. | News | Comments

It makes sense that the credit for sci­ence papers with mul­tiple authors should go to the authors who per­form the bulk of the research, yet that’s not always the case. Now a new algo­rithm devel­oped at Northeastern’s Center for Com­plex Net­work Research helps sheds light on how to prop­erly allo­cate credit.

Visual control of big data

August 15, 2014 7:55 am | by Larry Hardesty, MIT News Office | News | Comments

In the age of big data, visualization tools are vital. With a single glance at a graphic display, a human being can recognize patterns that a computer might fail to find even after hours of analysis. But what if there are aberrations in the patterns? Or what if there’s just a suggestion of a visual pattern that’s not distinct enough to justify any strong inferences? Or what if the pattern is clear, but not what was to be expected?

“Seeing” through virtual touch is believing

August 11, 2014 10:10 am | by Tom Robinette, Univ. of Cincinnati | News | Comments

Visual impairment comes in many forms, and it's on the rise in America. A Univ. of Cincinnati experiment aimed at this diverse and growing population could spark development of advanced tools to help all the aging baby boomers, injured veterans, diabetics and white-cane-wielding pedestrians navigate the blurred edges of everyday life.
