Value-State Gated Attention for Mitigating Extreme-Token Phenomena in Transformers
Rui Bu, Haofeng Zhong, Wenzheng Chen +1
Large models based on the Transformer architecture are susceptible to extreme-token phenomena, such as attention sinks and value-state drains. These issues, which degrade model per…
