bayespy.inference.vmp.nodes.node.Node

class bayespy.inference.vmp.nodes.node.Node(*parents, dims=None, plates=None, name='', notify_parents=True, plotter=None, plates_multiplier=None, allow_dependent_parents=False)

Base class for all nodes.

mask dims plates parents children name

Sub-classes must implement: 1. For computing the message to children:

get_moments(self):

2. For computing the message to parents: _get_message_and_mask_to_parent(self, index)

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

_compute_weights_to_parent(index, weights) _plates_to_parent(self, index) _plates_from_parent(self, index)

__init__(*parents, dims=None, plates=None, name='', notify_parents=True, plotter=None, plates_multiplier=None, allow_dependent_parents=False)
