New SAPER framework prunes Vision Transformer attention heads for efficiency

Researchers have developed SAPER, a novel framework for pruning attention heads in Vision Transformers. This method uses spectral analysis and visualization techniques based on the Laplacian eigenvectors of attention maps to identify and cluster redundant attention heads. SAPER, which employs a LapSum Soft Top-K approach, has demonstrated a favorable accuracy-efficiency trade-off on ImageNet-1K, outperforming the RAPTOR baseline in FLOPs reduction while maintaining strong classification performance.
