Behrooz Azarkhalili · Linyi Li · Maxwell W. Libbrecht
摘要
We introduce PR-XAI, a feature attribution method for transformer models based on the PageRank algorithm. The proposed PR-XAI models the attention mechanism as a directed graph, with weights derived from attention weights and their gradients. Evaluations across five well-known text classification...
