public class LogSTDPRule
extends STDPRule

An implementation of Log-STDP as introduced in: Gilson M, Fukai T (2011) Stability versus Neuronal Specialization for STDP: Long-Tail Weight Distributions Solve the Dilemma. PLoS ONE 6(10): e25339 doi:10.1371/journal.pone.0025339 Log-STDP pushes weight values toward a log normal distribution. This can help with weight divergence, which is common to Add and Mlt STDP. It also allows for specialization of synapses, and fits very well with experimental data concerning synaptic efficacy.
