The paper proposes a new architecture called Reinforcement Weighted Kernel Vector (RWKV) that can learn long-term dependencies in sequential data more efficiently than traditional Recurrent Neural Networks (RNNs). The authors compare the performance of their proposed model with several state-of-the-art RNN architectures on various benchmark datasets, including language modeling tasks such as text generation and machine translation. They show that RWKV achieves better results while using fewer parameters and requiring less computation time. One of the defining characteristics of RWKV is its ability to offer parallelized training and robust scalability, similar to Transformers. Moreover, the authors have reformulated the attention mechanism in RWKV to introduce a variant of linear attention, eschewing the traditional dot-product token interaction in favor of more effective channel-directed attention. This approach contrasts significantly with the traditional Transformer architecture, where specific token interactions predominantly drive attention. The implementation of linear attention in RWKV is carried out without approximation, which offers a considerable improvement in efficiency and enhances the scalability. The overarching motivation behind developing RWKV is to address the problem of gradient vanishing or exploding during training, which has been a major challenge for RNNs. By introducing weighted kernels, the authors have effectively mitigated this issue while maintaining the ability to learn long-term dependencies. Overall, RWKV represents an exciting new direction in sequential modeling that promises to offer significant improvements in performance and scalability.
