A new research paper explores the limitations of attention mechanisms in AI models when dealing with redundant or correlated information. The study identifies two distinct ways this redundancy impacts attention: repeated items increase normalization mass, while variations within correlated groups can lead to extreme individual scores. The research proposes that simply subtracting the log of cluster size from pre-softmax scores is insufficient, as it fails to address these within-cluster extremes. The paper suggests that averaging scores before exponentiation could be a more effective strategy for suppressing fluctuations and improving retrieval accuracy, particularly in scenarios with correlated distractors.
