Deep Learning and Explainable AI: New Pathways to Genetic Insights

Current interpretability methods in genomics lack rigorous theoretical foundations: The paper identifies that genetic researchers have historically relied on "intuition and experience rather than rigorous theoretical foundations" when interpreting AI model decisions, highlighting a significant gap in how we validate whether AI insights about genetic processes are actually trustworthy.

Two main categories of interpretability approaches exist with distinct tradeoffs: The authors systematically categorize interpretability methods into input-based approaches (examining which genetic data the model focuses on) and model-based approaches (understanding how the model processes information), each with different limitations that researchers should understand when choosing tools.

Interpretability methods have concrete limitations in real biological applications: Rather than treating interpretability as universally reliable, the paper critically evaluates these methods through "concrete biological application scenarios," suggesting that what works to explain an AI model in one genetic context may not work in another.

Mathematical rigor is needed to understand why interpretability methods fail: The authors establish "formal mathematical demonstrations" to explain the origins of interpretability constraints, suggesting that responsible use of AI in genetics requires understanding not just what these methods show, but why they sometimes mislead researchers.

The field needs practical guidance for future responsible AI development: The paper concludes with "feasible suggestions for future research," indicating that improving trustworthiness in genetic AI requires both better interpretability tools and clearer guidance for researchers designing and deploying these systems.
