Optimizing Transformer Attention for Long Sequences
A research team is developing a Transformer model for summarizing lengthy scientific articles. They encounter significant memory and computational speed limitations due to the quadratic complexity of the standard attention mechanism. During an analysis of the model's internal states, they consistently find that the attention matrix for any given layer can be closely approximated by a much simpler, lower-dimensional matrix without a significant drop in performance. Which category of attention improvement directly leverages this specific empirical finding, and how does it address the team's performance bottlenecks?

Linear Attention
A research team is working to reduce the computational cost of the attention mechanism for processing extremely long documents. Their proposed solution involves modifying the attention calculation so that each query token only computes attention scores with a small, fixed subset of key tokens (e.g., neighboring tokens and a few globally important tokens) instead of all tokens in the sequence. Which category of attention improvement best describes this approach?
