net = mlpinit(net, prior)
takes a 2-layer feedforward network
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).
