Researchers have demonstrated that local synaptic learning rules, specifically spike-timing-dependent plasticity (STDP+) and homeostatic plasticity, can effectively implement a SIGReg gradient for self-supervised learning. This method bypasses the need for traditional backpropagation, global error signals, or label information, relying solely on local firing statistics and temporal contiguity of sensory inputs. The approach showed promising results on a synthetic clustering task and achieved 87.3% linear-probe accuracy on temporally ordered MNIST data, indicating its potential for end-to-end functionality.
