A segmentation model of the ultrasound images of breast tumors based on virtual agents trained using reinforcement learning is proposed. The agents, living in the edge map, are able to avoid false boundaries, connect broken parts, and finally, accurately delineate the contour of the tumor. The agents move similarly to robots navigating in the unknown environment with the goal of maximizing the rewards. The individual agent does not know the goal of the entire population. However, since the robots communicate, the model is able to understand the global information and fit the irregular boundaries of complicated objects. Combining the reinforcement learning with a neural network makes it possible to automatically learn and select the local features. In particular, the agents handle the edge leaks and artifacts typical for the ultrasound images. The proposed model outperforms 13 state-of-the-art algorithms, including selected deep learning models and their modifications.
