Machine learning algorithms track facial cues focusing prominently on the eyes eyebrows and mouth. A smile for instance would mean the corners of the lips curl upward and outward teeth flash and the skin around their eyes wrinkles.

A novel control algorithm enables it to move in sync with the wearer s fingers to grasp objects of various shapes and sizes.

Among the tools that computer scientists are developing to make the profusion of video more useful are algorithms for activity recognition or determining
-recognition algorithm that has several advantages over its predecessors. One is that the algorithm s execution time scales linearly with the size of the video file it s searching.
That means that if one file is 10 times the size of another the new algorithm will take 10 times as long to search it not 1000 times
as long as some earlier algorithms would. Another is that the algorithm is able to make good guesses about partially completed actions
so it can handle streaming video. Partway through an action it will issue a probability that the action is of the type that it s looking for.
It may revise that probability as the video continues but it doesn t have to wait until the action is complete to assess it.
Finally the amount of memory the algorithm requires is fixed regardless of how many frames of video it s already reviewed.
The grammar of actionenabling all of these advances is the appropriation of a type of algorithm used in natural language processing the computer science discipline that seeks techniques for interpreting sentences written in natural language.
For any given action Pirsiavash and Ramanan s algorithm must thus learn a new grammar.
Pirsiavash and Ramanan feed their algorithm training examples of videos depicting a particular action and specify the number of subactions that the algorithm should look for.
But they don t give it any information about what those subactions are or what the transitions between them look like.
Pruning possibilitiesthe rules relating subactions are the key to the algorithm s efficiency. As a video plays the algorithm constructs a set of hypotheses about
which subactions are being depicted where and it ranks them according to probability. It can t limit itself to a single hypothesis as each new frame could require it to revise its probabilities.
The researchers tested their algorithm on eight different types of athletic endeavor such as weightlifting and bowling with training videos culled from Youtube.
They found that according to metrics standard in the field of computer vision their algorithm identified new instances of the same activities more accurately than its predecessors.

Now your face could be transformed instantly into a more memorable one without the need for an expensive makeover thanks to an algorithm developed by researchers in MIT s Computer science and Artificial intelligence Laboratory (CSAIL.
The algorithm which makes subtle changes to various points on the face to make it more memorable without changing a person s overall appearance was unveiled earlier this month at the International Conference on Computer Vision in Sydney.
It could also be used for job applications to create a digital version of an applicant s face that will more readily stick in the minds of potential employers says Khosla who developed the algorithm with CSAIL principal research scientist Aude Oliva the senior author of the paper Antonio
To develop the memorability algorithm the team first fed the software a database of more than 2000 images.
The researchers then programmed the algorithm with a set of objectives to make the face as memorable as possible
and so would fail to meet the algorithm s objectives. When the system has a new face to modify it first takes the image
The algorithm then analyzes how well each of these samples meets its objectives. Once the algorithm finds a sample that succeeds in making the face look more memorable without significantly altering the person s appearance it makes yet more copies of this new image with each containing further alterations.
It then keeps repeating this process until it finds a version that best meets its objectives.
When they tested these images on a group of volunteers they found that the algorithm succeeded in making the faces more or less memorable as required in around 75 percent of cases.
Now Oliva and her team have developed a computational algorithm that can do this for us he says.

and Systems Glover and MIT alumna Sanja Popovic 12 MENG 13 who is now at Google describes a new robot-vision algorithm based on the Bingham distribution that is 15 percent better than its best
That algorithm however is for analyzing high-quality visual data in familiar settings. Because the Bingham distribution is a tool for reasoning probabilistically it promises even greater advantages in contexts where information is patchy or unreliable.
In cases where visual information is particularly poor his algorithm offers an improvement of more than 50 percent over the best alternatives.
because it allows the algorithm to get more information out of each ambiguous local feature.

The current version of Glover and Popovic s algorithm integrates point-rotation probabilities with several other such probabilities.
In experiments involving visual data about particularly cluttered scenes depicting the kinds of environments in which a household robot would operate Glover s algorithm had about the same false positive-rate rate as the best existing algorithm:
Glover argues that that difference is because of his algorithm s better ability to determine object orientations.
He also believes that additional sources of information could improve the algorithm s performance even further.
