New RAPID framework boosts Vision Transformer efficiency via layer-wise token merging

Researchers have developed RAPID, a novel framework designed to make Vision Transformers (ViTs) more computationally efficient. This method intelligently prunes and merges tokens based on their layer-specific characteristics, addressing the quadratic complexity of self-attention. In earlier layers, RAPID removes redundant local patterns, while in deeper layers, it merges less critical tokens while preserving important ones, guided by attention weights. Experiments on ImageNet-1K showed RAPID achieving a better accuracy-compression trade-off than existing methods, especially under aggressive compression. AI
