bayespy.inference.vmp.nodes.stochastic.Distribution

class bayespy.inference.vmp.nodes.stochastic.Distribution[source]

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__($self, /, *args, **kwargs)

Initialize self. See help(type(self)) for accurate signature.

Methods

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.
