Sparse spike coding in an asynchronous feed-forward multi-layer neural network using Matching Pursuit

This paper introduced for the first time the use of Matching Pursuit in a neuromimetic architecture of low-level visual areas. It aims at understanding the efficiency and generality of correlation-based inhibition propagation, by showing:
