What is Missing? Explaining Neurons Activated by Absent Concepts

arXiv:2603.09787v2 Announce Type: replace-cross Abstract: Explainable artificial intelligence (XAI) aims to provide human-interpretable insights into the behavior of deep neural networks (DNNs), typically by estimating a simplified causal structure of the model. In existing work, this causal structure often includes relationships where the presence of a concept is associated with a strong activation of a neuron. For example, attribution methods primarily identify input pixels that contribute most to a prediction, and feature visualization methods reveal inputs that cause high activation of a t

Why this matters
Why now

The paper addresses a growing need for more transparent and trustworthy AI systems, particularly as deep neural networks become more complex and integrated into critical applications.

Why it’s important

This research contributes to making AI decision-making processes more understandable and debuggable, which is crucial for widespread adoption and regulatory compliance, particularly in high-stakes environments.

What changes

Current XAI methods primarily focus on identifying contributions of present features; this new approach extends explainability to understanding why certain expected concepts are *not* activated, offering a more complete picture of model reasoning.
