bayespy.inference.vmp.nodes.deterministic.Deterministic

class bayespy.inference.vmp.nodes.deterministic.Deterministic(*args, **kwargs)[source]

Base class for deterministic nodes.

Sub-classes must implement: 1. For implementing the deterministic function:

_compute_moments(self, *u)

  1. One of the following options: a) Simple methods:

    _compute_message_to_parent(self, index, m, *u)

    1. More control with: _compute_message_and_mask_to_parent(self, index, m, *u)

Sub-classes may need to re-implement: 1. If they manipulate plates:

_compute_weights_to_parent(index, mask) _compute_plates_to_parent(self, index, plates) _compute_plates_from_parent(self, index, plates)

__init__(*args, **kwargs)[source]

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