- pyhgf.updates.prediction_error.nodes.continuous.continuous_node_value_prediction_error(attributes: Dict, node_idx: int) Array[source]#
Compute the value prediction error of a state node.
The value prediction error \(\delta_j^{(k)}\) of a continuous state node is given by:
\[:math:`\delta_j^{(k)} = \mu_j^{k} - \hat{\mu}_j^{k}`.\]- Parameters:
- attributes
The attributes of the probabilistic nodes.
- node_idx
Pointer to the value parent node that will be updated.
- Returns:
- attributes
The attributes of the probabilistic nodes.
