bayespy.inference.vmp.nodes.stochastic.Distribution

class bayespy.inference.vmp.nodes.stochastic.Distribution

A base class for the VMP formulas of variables.

Sub-classes implement distribution specific computations.

If a sub-class maps the plates differently, it needs to overload the following methods:

• compute_weights_to_parent

• plates_to_parent

• plates_from_parent

__init__()

Methods

__init__()
compute_message_to_parent(parent, index, ...)	Compute the message to a parent node.
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(*params[, plates])	Draw a random sample from the distribution.
squeeze(axis)	Squeeze a plate axis from the distribution
