Algorithm
● Given a rating dataset where (some) items 
have been re­rated,
● Two fairness conditions:
1. Algorithm should remove as few ratings as 
possible (i.e. only when there is some 
certainty that the rating is only adding noise)
2.Algorithm should not make up new ratings but 
decide on which of the existing ones are 
  valid.
