Popis: | Neuro-evolutionary algorithms optimize the synaptic connectivity of sets of candidate neural networks based on a task-dependent fitness function. Compared to the commonly used methods from machine learning, many of them not only support the adaptation of connection weights but also of the network topology. However, the evaluation of the current fitness requires running every candidate network in every generation. This becomes a major impediment especially when using biologically inspired spiking neural networks which require considerable amounts of simulation time even on powerful computers. In this paper, we address this issue by offloading the network simulation to SpiNNaker, a state-of-the art neuromorphic hardware architecture which is capable of simulating large spiking neural networks in biological real-time. We were able to apply SpiNNaker's simulation power to the popular NEAT algorithm by running all candidate networks in parallel and successfully evolved spiking neural networks for solving the XOR problem and for playing the Pac-Man arcade game |
