Output accuracy = Mechanistic reliability ?

The high accuracy of the model outputs does not imply reliable underlying mechanisms.

Experientially judged data quality = The real utility of data?

Universal Matching & Sparsity Property

Guaranteed Faithfulness

The trustworthiness of interaction mechanisms is ensured by both the universal matching property and the sparsity property. This means that regardless of random masking applied to input variables, sparse interaction mechanisms can always accurately align with the output scores of a DNN.

AND-OR Interaction Mechanistic Evaluation

Mechanistic Evaluation for Reliable AI

Decomposign complex decision-making logic underlying billions of parameters into 50 to 150 interaction mechanisms, revealing potential risky representations.

Autonomous Driving Object Detection: Mechanism Risk Evaluation
Representation Risk Evaluation for Autonomous Driving Models

In pedestrian detection, we found that despite correct outputs, over 60% of interactions risk "cancellation effects," over 60% interactions represented overfitted patterns.

Legal LLM Judgment: Mechanism Evaluation
Mechanistic Evaluation of Legal LLM Judgments

While judgments were correct, the logic relied on spurious correlations, many interaction mechanisms employed by the LLM indicated spurious correlations.
