- pyhgf.updates.prediction_error.binary.binary_finite_state_node_prediction_error(attributes: Dict, node_idx: int, edges: Tuple[AdjacencyLists, ...], **args) Dict[source]#
Update the posterior of a binary node given finite precision of the input.
- Parameters:
- attributes
The attributes of the probabilistic nodes.
- node_idx
Pointer to the node that needs to be updated. After continuous updates, the parameters of value and volatility parents (if any) will be different.
- edges
The edges of the probabilistic nodes as a tuple of
pyhgf.typing.Indexes. The tuple has the same length as the node number. For each node, the index lists the value and volatility parents and children.
- Returns:
- attributes
The updated attributes of the probabilistic nodes.
