Sub-classes implement distribution specific computations.
Methods
__init__(N, D, K)compute_cgf_from_parents(u_mu, u_Lambda, ...)Compute CGF using the moments of the parents.
compute_fixed_moments_and_f(x[, mask])Compute u(x) and f(x) for given x.
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 a message to a parent.
compute_moments_and_cgf(phi[, mask])Compute the moments and the cumulant-generating function.
compute_phi_from_parents(u_mu, u_Lambda, ...)Compute the natural parameters using parents' moments.
compute_rotation_bound(u, u_mu_Lambda, u_A_V, R)compute_weights_to_parent(index, weights)Maps the mask to the plates of a parent.
plates_from_parent(index, plates)Compute the plates using information of a parent node.
plates_to_parent(index, plates)Computes the plates of this node with respect to a parent.
random(*params[, plates])Draw a random sample from the distribution.
rotate(u, phi, R[, inv, logdet])squeeze(axis)Squeeze a plate axis from the distribution
