mlpinit

Purpose

Initialise the weights in a 2-layer feedforward network.

Synopsis

net = mlpinit(net, prior)

Description

net = mlpinit(net, prior) takes a 2-layer feedforward network net and sets the weights and biases by sampling from a Gaussian distribution. If prior is a scalar, then all of the parameters (weights and biases) are sampled from a single isotropic Gaussian with inverse variance equal to prior. If prior is a data structure of the kind generated by mlpprior, then the parameters are sampled from multiple Gaussians according to their groupings (defined by the index field) with corresponding variances (defined by the alpha field).
