      • getBaselineOutputValue

        public double getBaselineOutputValue()
         Output only. Model predicted output if the input instance is constructed
 from the baselines of all the features defined in
 [ExplanationMetadata.inputs][google.cloud.aiplatform.v1.ExplanationMetadata.inputs].
 The field name of the output is determined by the key in

 If the Model's predicted output has multiple dimensions (rank > 1), this is
 the value in the output located by
 [output_index][google.cloud.aiplatform.v1.Attribution.output_index].

 If there are multiple baselines, their output values are averaged.

      • hasFeatureAttributions

        public boolean hasFeatureAttributions()
         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.
