Optimizing Relevance Maps of Vision Transformers Improves Robustness

Vision models are known to use "shortcuts" in the data, i.e. use irrelevant cues to achieve high accuracy. In this work, we show that using a short *few-shot* finetuning process on the relevance maps of ViTs, we can teach the model *why* the label is correct, and enforce that the predictions are based on the *right* reasons, resulting in a significant improvement in the robustness of ViTs.

Image-Based Clip-Guided Essence Transfer

This paper proposes a novel method to transfer the semantic properties that constitute high-level textual description from a target image to a source image, without changing the identity of the source. The method uses CLIP's image latent space, which is more stable and expressive than the textual latent space.

No Token Left Behind: Explainability-Aided Image Classification and Generation

The paper presents a novel use of explainability to perform zero-shot tasks such as image classification and generation. We demonstrate that CLIP guidance based on pure similarity scores between the image and text is unstable as the scores can be based on irrelevant or partial data. Our method demonstrates the effectiveness of using explainability to stabilize the scores.

Transformer Explainability Beyond Accountability (English)

This talk takes a deep dive into Transformer explainability algorithms, and demonstrates how explainability can be used to improve downstream tasks such as image editing, and even increase robustness and accuracy of image backbones.

Intro to Transformers and Transformer Explainability (English)

This talk takes a deep dive into the attention mechanism. During the talk, we review the motivations and applications of the self-attention mechanism. Additionally, we review the main building blocks for self-attention explainability and some cool applications of Transformer-explainability from recent research.

Generic Attention-model Explainability for Interpreting Bi-Modal and Encoder-Decoder Transformers (Oral)

The paper presents an interpretability method for all types of attention, including bi-modal Transformers and encoder-decoder Transformers. The method achieves SOTA results for CLIP, DETR, LXMERT, and more.

Transformer Interpretability Beyond Attention Visualization

This paper presents an interpretability method for self-attention based models, and specifically for Transformer encoders. The method incorporates LRP and gradients, and achieves SOTA results for ViT, BERT, and DeiT.
