TITLE: High-Dimensional Classification and Intermittency Modeling with
Scattering <http://www.pacm.princeton.edu/node/261> 


Invariant representations play a fundamental role to classify images and
audios signals, but also to analyze physical systems. Stability to
deformations is a key requirement in all these domains. We introduce a
scattering representation which builds stable invariants to translations or
the action of any Lie Group. It is calculated with a cascade of wavelet
tranforms and modulus non-linearities. Applications to image and audio
classifications will be shown. The representation of intermittent processes
and turbulent flows will be discussed.
