Selective Alignment Knowledge Distillation for Spiking Neural Networks

A recent study on arXiv introduces Selective Alignment Knowledge Distillation for Spiking Neural Networks (SNNs). These models, inspired by the brain and driven by spikes, are known for their exceptional energy efficiency but generally underperform compared to Artificial Neural Networks (ANNs). Current knowledge distillation techniques apply uniform alignment across all timesteps, treating each prediction as equally important. However, since SNN predictions change over time, not all intermediate predictions need to be accurate as long as the final output is correct. The new approach selectively aligns incorrect timesteps while maintaining beneficial temporal dynamics instead of pushing every timestep towards a single supervision target.
