Transformer Interpretability Beyond Attention VisualizationHila Chefer1 Shir Gur1 Lior Wolf1,21 The School of Computer Science, Tel Aviv University2 Facebook AI Research (FAIR)AbstractSelf- Attention techniques, and specifically Transformers,are dominating the field of text processing and are becom-ing increasingly popular in computer vision classificationtasks. In order to visualize the parts of the image thatled to a certain classification, existing methods either relyon the obtained Attention maps or employ heuristic prop-agation along the Attention graph. In this work, we pro-pose a novel way to compute relevancy for Transformernetworks. The method assigns local relevance based onthe Deep Taylor Decomposition principle and then prop-agates these relevancy scores through the layers. Thispropagation involves Attention layers and skip connections,which challenge existing methods.
