RePaViT: Scalable Vision Transformer Acceleration via Structural Reparameterization on Feedforward Network Layers Open
We reveal that feedforward network (FFN) layers, rather than attention layers, are the primary contributors to Vision Transformer (ViT) inference latency, with their impact signifying as model size increases. This finding highlights a crit…
