Scenario 3: Brain-Inspired Learning

Tutorials on biologically-inspired learning rules for neural networks, including Hebbian plasticity and associative memory.

Tutorials

Overview

This scenario explores brain-inspired learning algorithms that model synaptic plasticity mechanisms observed in biological neural systems.

Tutorial 1: Pattern Storage and Recall

  • Hebbian learning principle

  • Hopfield networks for associative memory

  • One-shot learning and pattern completion

  • Anti-Hebbian learning for decorrelation
