Effects of Introducing Synaptic Scaling on Spiking Neural Network Learning

Dec 02, 20252025 10th International Conference on Intelligent Informatics and Biomedical Sciences (ICIIBMS)

This work addresses the limited performance of spiking neural networks (SNNs) in unsupervised learning by integrating spike-timing-dependent plasticity (STDP) with L2-norm synaptic scaling within a winner-take-all (WTA) architecture. The study presents the first comprehensive evaluation of L2-norm synaptic scaling in SNN-based unsupervised learning, systematically investigating the effects of neuron count, STDP time constants, and synaptic weight normalization strategies. Experimental results demonstrate that the proposed approach significantly enhances classification accuracy under single-epoch training, achieving 88.84% on MNIST and 68.01% on Fashion-MNIST. These findings validate the efficacy and superiority of L2-norm synaptic scaling in improving unsupervised learning capabilities of SNNs.
