Neural Sampling Machine with Stochastic Synapse allows Brain-like Learning and Inference

no code implementations20 Feb 2021 Sourav Dutta, Georgios Detorakis, Abhishek Khanna, Benjamin Grisafe, Emre Neftci, Suman Datta

We experimentally show that the inherent stochastic switching of the selector element between the insulator and metallic state introduces a multiplicative stochastic noise within the synapses of NSM that samples the conductance states of the FeFET, both during learning and inference.

Contrastive Hebbian Learning with Random Feedback Weights

1 code implementation19 Jun 2018 Georgios Detorakis, Travis Bartley, Emre Neftci

It operates in two phases, the forward (or free) phase, where the data are fed to the network, and a backward (or clamped) phase, where the target signals are clamped to the output layer of the network and the feedback signals are transformed through the transpose synaptic weight matrices.

Neuromorphic Deep Learning Machines

1 code implementation16 Dec 2016 Emre Neftci, Charles Augustine, Somnath Paul, Georgios Detorakis

Building on these results, we demonstrate an event-driven random BP (eRBP) rule that uses an error-modulated synaptic plasticity for learning deep representations in neuromorphic computing hardware.

Forward Table-Based Presynaptic Event-Triggered Spike-Timing-Dependent Plasticity

no code implementations11 Jul 2016 Bruno U. Pedroni, Sadique Sheik, Siddharth Joshi, Georgios Detorakis, Somnath Paul, Charles Augustine, Emre Neftci, Gert Cauwenberghs

We present a novel method for realizing both causal and acausal weight updates using only forward lookup access of the synaptic connectivity table, permitting memory-efficient implementation.
