pyhgf.updates.prediction_error.continuous.continuous_node_prediction_error(attributes, node_idx, edges, **args)[source]#

Store prediction errors in an input node.

See [1] for more details.

Parameters:

  • attributes (dict) – The attributes of the probabilistic nodes.

  • note:: (..) – The parameter structure also incorporates the value and volatility coupling strength with children and parents (i.e. “value_coupling_parents”, “value_coupling_children”, “volatility_coupling_parents”, “volatility_coupling_children”).

  • node_idx (int) – Pointer to the continuous node.

  • edges (tuple[AdjacencyLists, ...]) – 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:

The updated attributes of the probabilistic nodes.

Return type:

attributes
