class bayespy.inference.vmp.nodes.multinomial.MultinomialDistribution(trials)[source]¶

Class for the VMP formulas of multinomial variables.

__init__(trials)[source]¶

Create VMP formula node for a multinomial variable

trials is the total number of trials.

Methods

`__init__`(trials)	Create VMP formula node for a multinomial variable
`compute_cgf_from_parents`(u_p)	Compute $\mathrm{E}_{q(p)}[g(p)]$

`compute_gradient`(g, u, phi)	Compute the Euclidean gradient.
`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, u_p)	Compute the message to a parent node.
`compute_moments_and_cgf`(phi[, mask])	Compute the moments and $g(\phi)$ .
`compute_phi_from_parents`(u_p[, 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.
