Attention Sinks Are Provably Necessary in Softmax Transformers: Evidence from Trigger-Conditional Tasks

Researchers prove that attention sinks in softmax Transformers are not just a byproduct of training but can be necessary for certain tasks, such as ignoring input when triggered. This finding highlights the importance of normalization constraints in driving sink behavior, offering key insights for content creators and model developers aiming to understand and mitigate issues related to attention mechanisms.
