Asymmetric Attention Heads: Structured Head-Wise Context Allocation for Transformer Attention
A new research paper introduces Asymmetric Attention Heads (AAH), a method that allocates different context lengths to different attention heads in Transformer models based on their functional roles, improving validation loss in controlled experiments.

Three Tokens Force Exponential Feature Rank in Nonnegative Kernel Attention
A theoretical machine learning paper proves exponential feature growth is necessary for nonnegative kernel attention to handle three-token sequences under Min-IP on Boolean inputs — revealing a fundamental expressivity gap versus full attention.
