    #   - accept a Compound, an Array of Compounds or a Dataset as first argument
    #   - optional parameters as second argument
    #   - return an object corresponding to the input type as result (eg. Compound -> value, Array of Compounds -> Array of values, Dataset -> Dataset with values

    # @param [Hash] Algorithm parameters
