Online Pseudo-Zeroth-Order Training of Neuromorphic Spiking Neural Networks

ICLR 2026poster

Brain-inspired neuromorphic computing with spiking neural networks (SNNs) is a promising energy-efficient computational approach. However, successfully training deep SNNs in a more biologically plausible and neuromorphic-hardware-friendly way is still challenging. Most recent methods leverage spatia…

Hebbian Learning based Orthogonal Projection for Continual Learning of Spiking Neural Networks

ICLR 2024poster

Neuromorphic computing with spiking neural networks is promising for energy-efficient artificial intelligence (AI) applications. However, different from humans who continually learn different tasks in a lifetime, neural network models suffer from catastrophic forgetting. How could neuronal operation…

Global Convergence of Over-parameterized Deep Equilibrium Models

AISTATS 2023poster

A deep equilibrium model (DEQ) is implicitly defined through an equilibrium point of an infinite-depth weight-tied model with an input-injection. Instead of infinite computations, it solves an equilibrium point directly with root-finding and computes gradients with implicit differentiation. In this…

Training Feedback Spiking Neural Networks by Implicit Differentiation on the Equilibrium State

NeurIPS 2021spotlight

Spiking neural networks (SNNs) are brain-inspired models that enable energy-efficient implementation on neuromorphic hardware. However, the supervised training of SNNs remains a hard problem due to the discontinuity of the spiking neuron model. Most existing methods imitate the backpropagation frame…
