New Method Diagnoses Neural Network Interpretations by Partitioning Input Space
A new approach has been introduced by researchers to diagnose interpretations within neural networks by pinpointing an input subspace that demonstrates a strong fidelity to a proposed interpretation. This technique is especially beneficial for causal-abstraction-style interpretability, where high-level causal hypotheses are assessed through interchange interventions. Rather than viewing the accuracy of these interventions as a singular global metric, the framework divides the input space into areas that are well-interpreted and those that are not, based on their pairwise behavior. This shift enables causal abstraction to serve as a diagnostic tool, highlighting the effectiveness and shortcomings of interpretations. Furthermore, it offers practical strategies for enhancing interpretations by examining the characteristics of both interpreted and under-interpreted regions. This method is detailed in a paper available on arXiv (2605.02234).
