A theory of cerebellar learning as spike-based reinforcement learning in continuous time and space.

ABSTRACT: The cerebellum has been considered to perform error-based supervised learning via long-term depression (LTD) at synapses between parallel fibers and Purkinje cells (PCs). Since the discovery of multiple synaptic plasticity other than LTD, recent studies have suggested that synergistic plasticity mechanisms could enhance the learning capability of the cerebellum. Indeed, we have proposed a concept of cerebellar learning as a reinforcement learning (RL) machine. However, there is still a gap between the conceptual algorithm and its detailed implementation. To close this gap, in this research, we implemented a cerebellar spiking network as an RL model in continuous time and space, based on known anatomical properties of the cerebellum. We confirmed that our model successfully learned a state
