Output only. Attributions of each explained feature. Features are extracted
from the [prediction
instances][google.cloud.aiplatform.v1.ExplainRequest.instances] according
to [explanation metadata for
inputs][google.cloud.aiplatform.v1.ExplanationMetadata.inputs].

The value is a struct, whose keys are the name of the feature. The values
are how much the feature in the
[instance][google.cloud.aiplatform.v1.ExplainRequest.instances] contributed
to the predicted result.

The format of the value is determined by the feature's input format:

  * If the feature is a scalar value, the attribution value is a
    [floating number][google.protobuf.Value.number_value].

  * If the feature is an array of scalar values, the attribution value is
    an [array][google.protobuf.Value.list_value].

  * If the feature is a struct, the attribution value is a
    [struct][google.protobuf.Value.struct_value]. The keys in the
    attribution value struct are the same as the keys in the feature
    struct. The formats of the values in the attribution struct are
    determined by the formats of the values in the feature struct.

The
[ExplanationMetadata.feature_attributions_schema_uri][google.cloud.aiplatform.v1.ExplanationMetadata.feature_attributions_schema_uri]
field, pointed to by the
[ExplanationSpec][google.cloud.aiplatform.v1.ExplanationSpec] field of the
[Endpoint.deployed_models][google.cloud.aiplatform.v1.Endpoint.deployed_models]
object, points to the schema file that describes the features and their
attribution values (if it is populated).
