Expressive probabilistic sampling in recurrent neural networks

1 code implementation NeurIPS 2023 Shirui Chen, Linxing Preston Jiang, Rajesh P. N. Rao, Eric Shea-Brown

We show that the firing rate dynamics of a recurrent neural circuit with a separate set of output units can sample from an arbitrary probability distribution.

Neural Co-Processors for Restoring Brain Function: Results from a Cortical Model of Grasping

1 code implementation19 Oct 2022 Matthew J. Bryan, Linxing Preston Jiang, Rajesh P N Rao

Approach: To achieve goal-directed closed-loop neurostimulation, we propose "neural co-processors" which use artificial neural networks and deep learning to learn optimal closed-loop stimulation policies, shaping neural activity and bridging injured neural circuits for targeted repair and rehabilitation.

Predictive Coding Theories of Cortical Function

no code implementations19 Dec 2021 Linxing Preston Jiang, Rajesh P. N. Rao

Specifically, the Rao-Ballard hierarchical predictive coding model assumes that the top-down feedback connections from higher to lower order cortical areas convey predictions of lower-level activities.

Improved Training of Sparse Coding Variational Autoencoder via Weight Normalization

no code implementations23 Jan 2021 Linxing Preston Jiang, Luciano de la Iglesia

We propose a few heuristics to improve the training of SVAE and show that a unit $L_2$ norm constraint on the decoder is critical to produce sparse coding filters.
