Unsupervised Hierarchical Sparse Coding algorithm inspired by Biological Vision

Abstract

The brain has to solve inverse problems to correctly interpret sensory data and infer the set of causes that generated the sensory inputs. Such a problem is typically ill-posed, and thus requires constraint the narrow down the number of solutions. Predictive coding (PC)is a computational neuroscience framework that finds the most likely causes for the sensory input by minimizing the mismatch between the sensory data and the predicted input. Such a framework could be used to build sparse hierarchical internal representations of a given input.

During my PhD, I focused on predictive coding in a bio-inspired neural network.
