No evidence for active sparsification in the visual cortex

no code implementations NeurIPS 2009 Pietro Berkes, Ben White, Jozsef Fiser

The proposal that cortical activity in the visual cortex is optimized for sparse neural activity is one of the most established ideas in computational neuroscience.

Characterizing neural dependencies with copula models

no code implementations NeurIPS 2008 Pietro Berkes, Frank Wood, Jonathan W. Pillow

The coding of information by neural populations depends critically on the statistical dependencies between neuronal responses.

On Sparsity and Overcompleteness in Image Models

no code implementations NeurIPS 2007 Pietro Berkes, Richard Turner, Maneesh Sahani

Computational models of visual cortex, and in particular those based on sparse coding, have enjoyed much recent attention.
