Adaptive Synaptic Failure Enables Sampling from Posterior Predictive Distributions in the Brain

no code implementations4 Oct 2022 Kevin McKee, Ian Crandell, Rishidev Chaudhuri, Randall O'Reilly

Bayesian interpretations of neural processing require that biological mechanisms represent and operate upon probability distributions in accordance with Bayes' theorem.

Locally Learned Synaptic Dropout for Complete Bayesian Inference

1 code implementation18 Nov 2021 Kevin L. McKee, Ian C. Crandell, Rishidev Chaudhuri, Randall C. O'Reilly

The random failure of presynaptic vesicles to release neurotransmitters may allow the brain to sample from posterior distributions of network parameters, interpreted as epistemic uncertainty.

Using noise to probe recurrent neural network structure and prune synapses

no code implementations NeurIPS 2020 Eli Moore, Rishidev Chaudhuri

Here we suggest that noise could play a functional role in synaptic pruning, allowing the brain to probe network structure and determine which synapses are redundant.

Bipartite expander Hopfield networks as self-decoding high-capacity error correcting codes

no code implementations NeurIPS 2019 Rishidev Chaudhuri, Ila Fiete

Neural network models of memory and error correction famously include the Hopfield network, which can directly store---and error-correct through its dynamics---arbitrary N-bit patterns, but only for ~N such patterns.

Associative content-addressable networks with exponentially many robust stable states

no code implementations6 Apr 2017 Rishidev Chaudhuri, Ila Fiete

The brain must robustly store a large number of memories, corresponding to the many events encountered over a lifetime.
