Researchers have developed a novel end-to-end reinforcement learning framework for segmenting tumors directly on whole-slide images (WSIs). This approach treats the WSI as an interactive, hierarchical environment, allowing an AI agent to navigate, zoom, and select tumor regions. Trained using Proximal Policy Optimization (PPO) with an actor-critic architecture, the system achieves comparable segmentation quality to traditional patch-based methods while significantly reducing inference time to mere seconds per slide. This method shows promise for advancing RL applications in computational pathology. AI
