RL and the brain seminar @ HMS
Harvard Medical School's biweekly RL and the brain seminar is a space for trainees to discuss the latest research in reinforcement learning (RL). Of particular interest to the seminar is research related to the neurobiology of RL: for example, how might the activity of midbrain dopaminergic neurons reflect a temporal difference learning algorithm?
