CRAFT: Concept Recursive Activation FacTorization for Explainability

CVPR 2023poster

Attribution methods are a popular class of explainability methods that use heatmaps to depict the most important areas of an image that drive a model decision. Nevertheless, recent work has shown that these methods have limited utility in practice, presumably because they only highlight the most sal…

Diffusion Models as Artists: Are we Closing the Gap between Humans and Machines?

ICML 2023oral

An important milestone for AI is the development of algorithms that can produce drawings that are indistinguishable from those of humans. Here, we adapt the ''diversity vs. recognizability'' scoring framework from Boutin et al (2022) and find that one-shot diffusion models have indeed started to clo…

Unlocking Feature Visualization for Deep Network with MAgnitude Constrained Optimization

NeurIPS 2023poster

Feature visualization has gained significant popularity as an explainability method, particularly after the influential work by Olah et al. in 2017. Despite its success, its widespread adoption has been limited due to issues in scaling to deeper neural networks and the reliance on tricks to generate…

A Benchmark for Compositional Visual Reasoning

NeurIPS 2022accept

A fundamental component of human vision is our ability to parse complex visual scenes and judge the relations between their constituent objects. AI benchmarks for visual reasoning have driven rapid progress in recent years with state-of-the-art systems now reaching human accuracy on some of these be…

What I Cannot Predict, I Do Not Understand: A Human-Centered Evaluation Framework for Explainability Methods

NeurIPS 2022accept

A multitude of explainability methods has been described to try to help users better understand how modern AI systems make decisions. However, most performance metrics developed to evaluate these methods have remained largely theoretical -- without much consideration for the human end-user. In parti…
