A Brain-inspired Algorithm for Training Highly Sparse Neural Networks

This repository contains code for the paper, "A Brain-inspired Algorithm for Training Highly Sparse Neural Networks" by Zahra Atashgahi, Joost Pieterse, Shiwei Liu, Decebal Constantin Mocanu, Raymond Veldhuis, Mykola Pechenizkiy. For more information please read the paper at https://arxiv.org/abs/1903.07138.

Methodology

algorithm

Results on highly sparse neural networks

results Classification accuracy (%) comparison among methods on a highly large and sparse3-layer MLP with a density lower than 0.22%.

Prerequisites
