Researchers from the University of Wisconsin-Madison developed CONDA, a framework to enhance the interpretability and robustness of foundation model-based systems under distribution shifts. CONDA significantly boosts accuracy and provides adaptively aligned concept-based explanations using only unlabeled test data.

Key insights

  • CBMs, even when built on powerful foundation models, can be less robust to distribution shifts than non-interpretable models if not adaptively adjusted.
  • Different types of distribution shifts (low-level vs. concept-level) require distinct adaptive mechanisms, validating CONDA's multi-component design.
  • Dynamically enriching the concept set (via RCB) is crucial for addressing 'incomplete concept set' failure modes, allowing for the discovery of new, relevant interpretive concepts.
