摘要

This work presents a biologically plausible approach to reinforcement learning control of benchmark cart-pole system with continuous state and discrete actions. The proposed solution utilizes brain-inspired spiking neural networks (SNN), constructed with the aid of the NEST simulator in Python. To update the SNN connection weights, the Temporal Difference TD(0) algorithm is combined with Spike Timing Dependent Plasticity (STDP), reflecting principles of reinforcement learning. It is shown that SNN actor-critic architecture solves the task several times faster than classical neural networks.
