Reinforcement learning using optomemristors (IMAGE)
Caption
Reinforcement learning using optomemristors. The left panel is a representation of the biophysical mechanisms which comprise a rodent’s navigation system. The directions are learned using reward-based three-factor plasticity in the optomemristive synapses. The right panel illustrates how by mapping the electrical signals to a global reward and optical signals to local neural activity, an artificial neural network learns to navigate the path of finding cheese in a maze.
