A ResNet-50 Classifier with Grad-CAM and SHAP for Explainable Breast Cancer Detection in Dense Mammography: Comparison with Human Radiologist Performance

This study demonstrates that a ResNet-50 classifier enhanced with Grad-CAM and SHAP explanations can surpass human radiologist sensitivity in detecting breast cancer within dense mammograms, achieving 72.2% sensitivity while providing actionable visual insights to support its deployment as a second-reader tool that flags high-confidence cases and defers ambiguous ones to clinicians.

Accumulated-History Replicator SelectionOptimization: Algorithm Design, TheoreticalGrounding, and Experimental Analysis (MycelialNetwork Optimization)

This paper introduces the Accumulated-History Replicator Selection (AHRS) framework and its Mycelial Network Optimization (MNO) algorithm, which leverage exponentially weighted historical fitness data to outperform standard population-based optimizers on complex, non-separable landscapes while being theoretically grounded in evolutionary game theory and Fisher's Fundamental Theorem.
