A BayesNode is a DirectedNode wih additional information such as a
Potential. A Potential is either a PD in the CBnet case, or a PAD in the
QBnet case. abbreviations in MyConstants.py. value of node = state of node.
Attributes
----------
__active_states : list[int]
When all states are active, use range(self.size)
clique : Clique
In a JoinTree, the family of any node belongs
to exactly one clique, stored here. The family of a node
is the node and its parents. The nodes on which a
node's potential depends are its family.
potential : Potential
size : int
number of values = number of states of node =
size of node
state_names : list[str]
children : set[Node]
neighbors : set[Node]
parents : set[Node]
id_num : int
topo_index : int
name : str
visited : bool
| def nodes.BayesNode.BayesNode.__init__ | ( | self, | |
| id_num, | |||
name = "blank", |
|||
size = 2 |
|||
| ) |
Constructor.
Parameters
----------
id_num : int
This should be a different int for each node.
name : str
The name of the node. Optional.
Returns
-------
| def nodes.BayesNode.BayesNode.forget_all_evidence | ( | self | ) |
Expand list of self's active states to include all possible states from 0 to size-1. Returns ------- None
| def nodes.BayesNode.BayesNode.get_active_states | ( | self | ) |
Getter for active state list. Returns ------- list[int]
| def nodes.BayesNode.BayesNode.resize | ( | self, | |
| size | |||
| ) |
Add or remove nodes taking care to change everything that depends on number of nodes. Parameters ---------- size : int Returns ------- None
| def nodes.BayesNode.BayesNode.set_active_states | ( | self, | |
| states | |||
| ) |
Setter for active state list. Parameters ---------- states : list[int] Returns ------- None
| def nodes.BayesNode.BayesNode.set_potential | ( | self, | |
| pot | |||
| ) |
Parameters ---------- pot : Potential Returns ------- None
| def nodes.BayesNode.BayesNode.set_state_name | ( | self, | |
| position, | |||
| name | |||
| ) |
Changes name of state of node. Parameters ---------- position : int name : str Returns ------- None
| def nodes.BayesNode.BayesNode.set_state_names_to_product | ( | self, | |
| list_of_iters, | |||
repeat = 1, |
|||
trim = False |
|||
| ) |
Sets state names to a sequence of tuples generate by it.product().
trim option to remove punctuation marks.
Parameters
----------
list_of_iters : list[str] | list[list[int]]
list of iterables like a list of one or more strings, or a list of
one or more lists of ints
repeat : int
In case list_of_iters is list of single string or list of single
list of ints, repeat them
trim : bool
Whether to keep punctuation or not. True removes white spaces,
commas and parentheses
Returns
-------
None
| def nodes.BayesNode.BayesNode.st_name_index | ( | self, | |
| st_name | |||
| ) |
returns index in state_names list given name Parameters ---------- st_name : str Returns ------- int
