Before revision:   Here, we report a hybrid spiking neural network model that integrates the two approaches by introducing a  meta-local module and a two-phase causality modellingmethod. The model can not only optimize local plasticityrules, but also receive top-down supervision information .
After revision:  Here, we report a hybrid spiking neural network model that integrates the two approaches by introducing a meta-local module and a two-phase parametric modelling. The hybrid model can meta-learn general local plasticity, and receive top-down supervision information .
