Tomaso Poggio – Massachusetts Institute of Technology.

In Machine Learning and Computer Vision, M-Theory is a learning framework inspired by feed-forward processing in the ventral stream of visual cortex and originally developed for recognition and classification of objects in visual scenes. M-Theory was later applied to other areas, such as speech recognition. On certain image recognition tasks, algorithms based on a specific instantiation of M-Theory, HMAX, achieved human-level performance.[1]

The core principle of M-Theory is extracting representations invariant to various transformations of images (translation, scale, 2D and 3D rotation and others). In contrast with other approaches using invariant representations, in M-Theory they are not hardcoded into the algorithms, but learned. M-Theory also shares some principles with Compressed Sensing. The theory proposes multilayered hierarchical learning architecture, similar to that of visual cortex.
