ca.nengo.model.plasticity.impl.PESTermination
A termination whose transformation evolves according to the PES rule. The learning rate is defined by an AbstractRealLearningFunction (see its declaration for the inputs it receives). This learning rate function is applied to each In each case, the presynaptic-variable input to the function is the corresponding dimension of input to the Termination. The postsynaptic variable is taken as the corresponding dimension of the Origin NEFEnsemble.X. This implementation supports only a single separate modulatory variable, though it can be multi-dimensional. This is also user-defined, as some other Termination onto the same NEFEnsemble.
