Identifying Structural Biases from Causal Mechanism Shifts

arXiv:2606.18834v1 Announce Type: new Abstract: Causal discovery methods commonly assume that all data is independently and identically distributed (i.i.d.) and that there are no unmeasured variables affecting the system. In practice, these assumptions are often violated, leading to inaccurate inference. In this paper, we study how to identify hidden confounding and selection biases from causal mechanism shifts. In particular, we show that structural biases lead to dependent mechanism shifts. That is, by considering for which variables the mechanisms change given data from different environmen

Why this matters
Why now

The proliferation of complex AI systems across various domains necessitates more robust and reliable causal inference to identify and mitigate biases that undermine their performance and fairness.

Why it’s important

This research is crucial for developing trustworthy AI systems by providing methods to identify and address hidden biases, which directly impacts the accuracy, reliability, and ethical deployment of AI.

What changes

Our ability to diagnose structural biases in AI models will improve, moving beyond mere correlation to understanding underlying causal mechanisms and their environmental dependencies.
