    Implement this method to combine multiple algorithms' predictions to produce a single final prediction.

    Implement this method to combine multiple algorithms' predictions to produce a single final prediction. The query is the original query sent to the engine, not the supplemented produced by LServing.supplement.

    query

    Original input query.

    predictions

    A list of algorithms' predictions.
