Researchers have developed a new deep learning architecture for analyzing retinal fundus images that utilizes sparse conditional computation. This model pairs a Guided Context Gating (GCG) spatial attention front-end with a sparsely-routed Mixture-of-Experts (MoE) block. The system demonstrates that expert allocation is significantly dependent on the disease present, with distinct pathologies like ERM and AMD isolating to specific experts. The model achieved a macro AUC of 0.912 and a macro F1 score of 0.653 on a five-class benchmark, with visualizations confirming that expert routing aligns with localized lesions and geometrically maps co-occurring cases.
