Description:
 def predict(self, comparison_vectors):
 """Predict the class of the record pairs. Classify a set of record pairs based on their comparison vectors into matches, non-matches and possible matches. The classifier has to be trained to call this method. Parameters comparison_vectors : pandas.DataFrame Dataframe with comparison vectors. return_type : str Deprecated. Use recordlinkage.options instead. Use the option `recordlinkage.set_option('classification.return_type', 'index')` instead. Returns ------- pandas.Series A pandas Series with the labels 1 (for the matches) and 0 (for the non-matches). """
