Feedback attention is explored as a key component to enhance Transformers by mimicking neural working memory. Working memory in neuroscience involves temporarily holding and processing information, contrasting with long-term memory stored in neural network weights. The proposed feedback attention mechanism sustains activation through continuous feedback loops, aiming to extend the effective context size of Transformers. This approach is likened to recurrent neural networks (RNNs) but seeks to capture short-term memory more effectively. Ultimately, comparisons with previous models reveal both advantages and limitations, emphasizing the need for continued research in integrating memory retention in AI architectures.
