Description
Entity resolution (ER) is the problem of matching records that represent the same real-world entity and then merging the matching records. ER is a well known problem that arises in many applications. An exhaustive ER process involves comparing all the pairs of records, which can be very expensive for large datasets.
Parameters
$n$: number of records
$k$: number of features
