Gradient-based Neuromorphic Learning on Dynamical RRAM Arrays

no code implementations26 Jun 2022 Peng Zhou, Jason K. Eshraghian, Dong-Uk Choi, Wei D. Lu, Sung-Mo Kang

We present MEMprop, the adoption of gradient-based learning to train fully memristive spiking neural networks (MSNNs).

SPICEprop: Backpropagating Errors Through Memristive Spiking Neural Networks

no code implementations2 Mar 2022 Peng Zhou, Jason K. Eshraghian, Dong-Uk Choi, Sung-Mo Kang

The natural spiking dynamics of the MIF neuron model are fully differentiable, eliminating the need for gradient approximations that are prevalent in the spiking neural network literature.

A Fully Memristive Spiking Neural Network with Unsupervised Learning

no code implementations2 Mar 2022 Peng Zhou, Dong-Uk Choi, Jason K. Eshraghian, Sung-Mo Kang

We present a fully memristive spiking neural network (MSNN) consisting of physically-realizable memristive neurons and memristive synapses to implement an unsupervised Spiking Time Dependent Plasticity (STDP) learning rule.
