Collapse or Preserve: Data-Dependent Temporal Aggregation for Spiking Neural Network Acceleration
🤖AI Summary
Researchers developed Temporal Aggregated Convolution (TAC) to accelerate spiking neural networks by aggregating spike frames before convolution, achieving 13.8x speedup on rate-coded data. The study reveals that optimal temporal aggregation strategies depend on data type - collapsing temporal dimensions for rate-coded data while preserving them for event-based data.
Key Takeaways
- →Traditional sparse computation strategies for spiking neural networks fail to outperform dense convolution on SIMD architectures like GPUs.
- →TAC achieves significant speedups (13.8x on MNIST) while improving accuracy by reducing convolution calls from T to T/K.
- →TAC-TP preserves temporal resolution for event-based data, maintaining 95.1% accuracy vs 91.3% with standard TAC on DVS128-Gesture.
- →The optimal temporal aggregation strategy is data-dependent, requiring different approaches for rate-coded versus event-based data.
- →Speedup benefits are hardware-agnostic, with 11.0x acceleration confirmed on NVIDIA V100 GPUs.
