Explainability in mulimodal deep transformation models for stroke outcome prediction

arXiv:2504.06299v2 Announce Type: replace-cross Abstract: Multimodal prediction models based on imaging and clinical data are increasingly used for clinical decision support, yet their interpretability remains limited. We present multimodal Deep Transformation Models (DTMs) combining statistical approaches and neural networks to achieve strong predictive performance while preserving interpretability for tabular data. A key contribution of this work is the adaption of the xAI methods Grad-CAM and Occlusion to DTMs relying on 3D CNNs, enabling interpretation of the image branch through the gener

Why this matters
Why now

The increasing adoption of AI in critical fields like medicine necessitates greater transparency and interpretability, leading to a surge in explainable AI research.

Why it’s important

Improved interpretability in medical AI models can enhance clinician trust and accelerate the deployment of AI for more accurate and explainable patient outcomes, particularly in conditions like stroke.

What changes

This development offers a refined methodology for understanding complex multimodal AI predictions in clinical settings, potentially bridging the gap between raw AI output and actionable medical insight.
