Description:
 def compute(self, pairs, x=None, x_link=None):
 """Return continuous random values for each record pair. Parameters pairs : pandas.MultiIndex A pandas MultiIndex with the record pairs to compare. The indices in the MultiIndex are indices of the DataFrame(s) to link. x : pandas.DataFrame The DataFrame to link. If `x_link` is given, the comparing is a linking problem. If `x_link` is not given, the problem is one of deduplication. x_link : pandas.DataFrame, optional The second DataFrame. Returns ------- pandas.Series, pandas.DataFrame, numpy.ndarray The result of comparing record pairs (the features). Can be a tuple with multiple pandas.Series, pandas.DataFrame, numpy.ndarray objects. """
