Not All Timesteps Matter Equally: Selective Alignment Knowledge Distillation for Spiking Neural Networks
arXiv:2605.14252v2 Announce Type: replace Abstract: Spiking neural networks (SNNs), which are brain-inspired and spike-driven, achieve high energy efficiency. However, a performance gap between SNNs and artificial neural networks (ANNs) still remains. Knowledge distillation (KD) is commonly adopted to improve SNN performance, but existing methods typically enforce uniform alignment across all timesteps, either from a teacher network or through inter-temporal self-distillation, implicitly assuming that per-timestep predictions should be treated equally. In practice, SNN predictions vary and evo
The continuous push for more efficient AI hardware and algorithms makes advances in SNN performance highly relevant as compute demands increase.
Improving SNN performance through methods like selective alignment knowledge distillation could significantly reduce the energy footprint of AI, impacting its scalability and adoption in edge devices.
This research suggests a more nuanced approach to SNN training that could close the performance gap with ANNs, making energy-efficient spiking networks more viable for complex tasks.
