wolffd@0: Description wolffd@0:

wolffd@0: wolffd@0:

net = netinit(net, prior) takes a network data structure wolffd@0: net and sets the weights and biases by sampling from a Gaussian wolffd@0: distribution. If prior is a scalar, then all of the parameters wolffd@0: (weights and biases) are sampled from a single isotropic Gaussian with wolffd@0: inverse variance equal to prior. If prior is a data wolffd@0: structure of the kind generated by mlpprior, then the parameters wolffd@0: are sampled from multiple Gaussians according to their groupings wolffd@0: (defined by the index field) with corresponding variances wolffd@0: (defined by the alpha field). wolffd@0: wolffd@0:
