Summary

In this webinar, Dr Chris Banerji presents his research on trustworthy AI for medicine and scientific discovery. He begins by introducing a mathematical framework for ’explaining the unseen’ in complex partially observable dynamical systems, drawing on information theory and differential geometry. He illustrates this with examples from stem cell differentiation, showing that signaling entropy decreases during differentiation and is elevated in cancer, serving as a prognostic marker. He then introduces a normalized Ricci flow approach to predict full differentiation trajectories, validated on time-course data. He also shows that well-trained deep neural networks exhibit Ricci flow-like data deformation, which correlates with better generalization. The second part focuses on clinical AI, particularly a platform called MDM AI designed to support multidisciplinary cancer meetings. He emphasizes three pillars: transparent clinically aligned reasoning via concept bottleneck models, fairness via conformal prediction, and trust via co-design. He discusses challenges of concept bottleneck models, including information leakage, optimal intervention, and the accuracy-interpretability trade-off, and outlines ongoing work to address them. Finally, he touches on using interpretable AI for scientific discovery, positioning it as a tool for both clinical and research purposes.
