Researchers have developed a novel gradient tunneling (GT) algorithm to address the challenge of temporal credit assignment in neural microcircuits (NMCs). This new framework, utilizing the lead-lag expansion technique, derives learning credit from local synaptic spike timing, offering a biologically plausible explanation for brain learning mechanisms. The GT algorithm enables an online feedback learning framework for NMCs, demonstrating superior performance in long-timescale evidence integration and memory retention compared to existing methods, while using fewer parameters. This approach is also compatible with hybrid artificial neural network (ANN) and spiking neural network (SNN) architectures. AI
