            [featureAttributions][google.cloud.aiplatform.v1beta1.Attribution.feature_attributions]

            index_display_name_mapping (google.protobuf.struct_pb2.Value):
                Static mapping between the index and display name.

                Use this if the outputs are a deterministic n-dimensional
                array, e.g. a list of scores of all the classes in a
                pre-defined order for a multi-classification Model. It's not
                feasible if the outputs are non-deterministic, e.g. the
                Model produces top-k classes or sort the outputs by their
                values.

                The shape of the value must be an n-dimensional array of
                strings. The number of dimensions must match that of the
                outputs to be explained. The
                [Attribution.output_display_name][google.cloud.aiplatform.v1beta1.Attribution.output_display_name]
                is populated by locating in the mapping with
                [Attribution.output_index][google.cloud.aiplatform.v1beta1.Attribution.output_index].

                This field is a member of `oneof`_ ``display_name_mapping``.
            display_name_mapping_key (str):
                Specify a field name in the prediction to look for the
                display name.

                Use this if the prediction contains the display names for
                the outputs.

                The display names in the prediction must have the same shape
                of the outputs, so that it can be located by
                [Attribution.output_index][google.cloud.aiplatform.v1beta1.Attribution.output_index]
                for a specific output.

                This field is a member of `oneof`_ ``display_name_mapping``.
            output_tensor_name (str):
                Name of the output tensor. Required and is
                only applicable to Vertex AI provided images for
                Tensorflow.
