Diagnosing Attention Head Redundancy
An engineer observes that during the training of a transformer-based model, several attention heads within the same layer consistently produce nearly identical attention patterns for a wide variety of inputs. Despite the model having many heads, this redundancy seems to limit the model's ability to capture diverse linguistic features. This scenario highlights a key motivation for developing more advanced attention mechanisms. What is the most direct problem with the standard multi-head attention design that this observation reveals?
