VRWKV's linear complexity attention mechanism offers a significant advantage over traditional transformers like ViT in terms of computational efficiency. While ViT relies on quadratic complexity for its attention mechanism, VRWKV utilizes a linear complexity bidirectional attention approach. This means that as the input size increases, VRWKV can maintain stable and efficient processing without the exponential increase in computational demands seen in ViT. By incorporating modifications such as Q-Shift and flexible decay parameters, VRWKV achieves global attention with reduced computational overhead compared to traditional transformers.
