## Image Classification with Invariant Representations

Wednesday, April 6, 2011 Stéphane Mallat |

### Abstract:

Classification requires finding appropriate metrics to compare signals. Audio and visual perceptual metrics remain a mystery. They are invariant to particular groups of transformations such as translations and scaling and are continuous to deformations relatively to these group actions. Such invariant representations can linearize classification problems, but finding them is a challenge.
