Implemented NN weight regularisation (weight decay) for both PSO and backpropagation.
Distance-based neighbourhood
NN Output Activations Measurement

Added the NNOutputActivations measurement to be able to extract the
resulting predictions/classifications made by the NN after each
iteration. An example of where this is useful, is where analysis on the
actual predictions of a given NN has to be made for an experiment such
as Time Series Data Analysis
