Machine Learning Recognizes Unknown Events in YouTube Videos

sing deep learning techniques, a group of researchers has trained a computer to recognize events in videos on YouTube — even the ones the software has never seen before like riding a horse, baking cookies or eating at a restaurant. Researchers from Disney Research and Shanghai’s Fudan University used both scene and object features from the video and enabled link between these visual elements and each type of event to be automatically determined by a machine-learning architecture known as neural network. “Notably, this approach not only works better than other methods in recognizing events in videos, but is significantly better at identifying events that the computer program has never or rarely encountered previously,” said Leonid Sigal, senior research scientist at Disney Research. Automated techniques are essential for indexing, searching and…
