NEC has developed new technology to help facilitate deep learning in its machine vision technologies, the company has announced. The technology revolves around'regularization', a concept concerning something like focus in artificial intelligence. As NEC explains, a deep learning system can become "excessively familiar" with data it is trained on, according to a statement; and this can result in the system being unable to recognize unfamiliar data. This unfortunate situation is one of "overtraining," and can adversely affect accuracy in machine vision. NEC's solution is to regulate learning in order to prevent this from happening.
