Methods
__init__
(shape)Initialize self. compute_cgf_from_parents
(u_mu_Lambda)Compute compute_fixed_moments_and_f
(x[, mask])Compute the moments and for a fixed value.
compute_gradient
(g, u, phi)Compute the standard gradient with respect to the natural parameters. compute_logpdf
(u, phi, g, f, ndims)Compute E[log p(X)] given E[u], E[phi], E[g] and E[f]. compute_message_to_parent
(parent, index, u, …)Compute the message to a parent node. compute_moments_and_cgf
(phi[, mask])Compute the moments and .
compute_phi_from_parents
(u_mu_Lambda[, mask])Compute the natural parameter vector given parent moments. compute_weights_to_parent
(index, weights)Maps the mask to the plates of a parent. plates_from_parent
(index, plates)Resolve the plate mapping from a parent. plates_to_parent
(index, plates)Resolves the plate mapping to a parent. random
(*phi[, plates])Draw a random sample from the distribution.
