            class. However, you can configure the explanation request to
            generate Shapley values for any other classes too. For
            example, if a model predicts a probability of ``0.4`` for
            approving a loan application, the model's decision is to
            reject the application since
            ``p(reject) = 0.6 > p(approve) = 0.4``, and the default
            Shapley values would be computed for rejection decision and
            not approval, even though the latter might be the positive
            class.

            contributed to the predicted result.

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

            - If the feature is a scalar value, the attribution value is

              [array][google.protobuf.Value.list_value].

            - If the feature is a struct, the attribution value is a

              the attribution value struct are the same as the keys in

            of the output vector. Indices start from 0.
