net = mlpinit(net, prior)
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).
