Effect of top-down connections in Hierarchical Sparse Coding

1 code implementation3 Feb 2020 Victor Boutin, Angelo Franciosini, Franck Ruffier, Laurent Perrinet

In this study, a new model called 2-Layers Sparse Predictive Coding (2L-SPC) is introduced to assess the impact of this inter-layer feedback connection.

Sparse Deep Predictive Coding captures contour integration capabilities of the early visual system

1 code implementation20 Feb 2019 Victor Boutin, Angelo Franciosini, Frederic Chavane, Franck Ruffier, Laurent Perrinet

Third, we demonstrate at the representational level that the SDPC feedback connections are able to overcome noise in input images.

no code implementations4 Dec 2018 Victor Boutin, Angelo Franciosini, Franck Ruffier, Laurent U. Perrinet

The formation of connections between neural cells is emerging essentially from an unsupervised learning process.
