## Breaking Changes

*   `tf.keras`:
    *   In `tf.keras.applications` the name of the "top" layer has been
        standardized to "predictions". This is only a problem if your code
        relies on the exact name of the layer.
    *   Huber loss function has been updated to be consistent with other Keras
        losses. It now computes mean over the last axis of per-sample losses

    /**
     * Gets the problems that were encountered during the model building. Note that only problems of severity
     * {@link ModelProblem.Severity#WARNING} and below are reported here. Problems with a higher severity level cause
     * the model builder to fail with a {@link ModelBuildingException}.
     *

     * @param problems The container used to collect problems that were encountered, must not be {@code null}.
     * @return The interpolated model, never {@code null}.
