CoRE Framework Enhances Continual Learning for Brain Lesion Segmentation

Researchers propose Concept-Reasoning Expansion (CoRE), a framework for continual learning in brain lesion segmentation from MRI. CoRE integrates visual features with structured concepts via a hierarchical concept library, simulating clinical reasoning to guide expert routing and demand-based expansion. This addresses capacity limits and redundant parameter growth in existing CL methods, handling pathological and multimodal heterogeneity.
