PrimeSVT: An Automated Memory-aware Pruning Framework with Prioritized Compression Policy for Spiking Vision Transformers
Summary
PrimeSVT is a novel automated memory-aware structured pruning framework designed to compress large Spiking Vision Transformers (SViTs), which typically hinder embedded implementation. Unlike state-of-the-art unstructured pruning methods requiring specialized hardware and manual design, PrimeSVT maximizes efficiency gains during inference on widely-used computing architectures. The framework operates by sorting SViT layers by parameter size, identifying robust pruning targets, and then sequentially compressing layers from largest to smallest using a prioritized compression policy. It employs channel-wise filter pruning based on L2-norm values, adhering to user-defined accuracy and memory constraints. Experimental results demonstrate PrimeSVT saves 26.68% memory while maintaining accuracy within 3% of the original 73.3% SViT model, achieving 70.3% without fine-tuning and 72.9% with fine-tuning.
Key takeaway
For Machine Learning Engineers deploying Spiking Vision Transformers (SViTs) to embedded systems, PrimeSVT offers a critical solution. You can now automate structured pruning to significantly reduce model memory footprint by 26.68% while ensuring accuracy remains within 3% of the original. This eliminates manual design time and specialized hardware needs, streamlining the deployment of SViTs on widely-used computing architectures.
