JSM helps catch "Clever Hans" behavior in medical AI: The paper addresses a critical problem where AI models can make correct predictions for the wrong reasons—using spurious correlations or biases rather than genuine medical indicators. The Jacobian Saliency Map (JSM) approach helps detect and eliminate this hidden bias, which is essential for trustworthy medical AI systems.
Interpretability and accuracy can improve together: Rather than treating explainability as a trade-off with performance, this research demonstrates that using JSM for model debugging actually enhanced both interpretability and diagnostic accuracy for Alzheimer's disease detection, suggesting responsible AI practices can strengthen rather than compromise medical AI performance.
Multimodal AI with interpretability tools better captures disease complexity: The study shows that combining multiple data types (likely imaging and other biomarkers) with interpretable debugging methods can more effectively track Alzheimer's progression across its multiple stages, providing clinicians with insights into the specific brain abnormalities driving the AI's predictions.
Current XAI methods have significant limitations: The paper highlights that existing explainable AI approaches can generate misleading counterfactual explanations and may not reveal when models are relying on problematic patterns, underscoring the need for more rigorous model debugging methodologies in high-stakes medical applications.
Model debugging should be standard practice in medical AI: By framing interpretability as an active debugging process rather than passive explanation, this work suggests that medical AI systems should routinely be tested for hidden biases and spurious correlations before clinical deployment.

Abstract

The evolution of deep learning and artificial intelligence has significantly reshaped technological landscapes. However, their effective application in crucial sectors such as medicine demands more than just superior performance, but trustworthiness as well. While interpretability plays a pivotal role, existing explainable AI (XAI) approaches often do not reveal {\em Clever Hans} behavior where a model makes (ungeneralizable) correct predictions using spurious correlations or biases in data. Likewise, current post-hoc XAI methods are susceptible to generating unjustified counterfactual examples. In this paper, we approach XAI with an innovative {\em model debugging} methodology realized through Jacobian Saliency Map (JSM). To cast the problem into a concrete context, we employ Alzheimer's disease (AD) diagnosis as the use case, motivated by its significant impact on human lives and the formidable challenge in its early detection, stemming from the intricate nature of its progression. We introduce an interpretable, multimodal model for AD classification over its multi-stage progression, incorporating JSM as a modality-agnostic tool that provides insights into volumetric changes indicative of brain abnormalities. Our extensive evaluation including ablation study manifests the efficacy of using JSM for model debugging and interpretation, while significantly enhancing model accuracy as well.
