The metadata of the output attributes is created with the following rules.

Context Rule

Attribute Name

Context Name

Description

All the output attributes of this component

field_path

List of the superordinate concepts of each output attribute based on the following hierarchical structure of the output attributes:

<component_id>_std_actual, <component_id>_std_predict, <component_id>_std_predict_c<hme_comp_id>

mean

Mean of the target values for learning.

<component_id>_std_actual, <component_id>_std_predict, <component_id>_std_predict_c<hme_comp_id>

std

Standard deviation of the target values for learning.

<component_id>_assigned_comp_id

active_comp_ids

List of component IDs corresponding to each prediction formula.

Derivation Rule

Attribute Name

Derived From

<component_id>_actual, <component_id>_std_actual

Derived from the target attribute.

<component_id>_predict, <component_id>_std_predict

Derived from the attributes which have non-zero coefficients in any prediction formula.

<component_id>_assigned_comp_id

Derived from the attributes used in the gating functions.

<component_id>_predict_c<hme_comp_id>, <component_id>_std_predict_c<hme_comp_id>

Derived from the attributes which have non-zero coefficients in the prediction formula of component id, <hme_comp_id>.

<component_id>_basisfunc_<feature_attr_name>:<basis_function_index>

Derived from the attribute of the name of <feature_attr_name>.
