How are my recommendations calculated?
The recommendations are calculated by picking the movies with the highest recommendation rating. The exact formula used to determine the recommendation rating of a movie is as follows:
recommendationRating(M) = S(M) × SW + F(M) × FW + D(M) × DW
Where:
- M: A movie that is seen by at least one neighbor but not by you
- S(M): Number of times movie M has been seen by your neighbors but not by you
- SW: Weight applied to seen movie = 1
- F(M): Number of times movie M has been marked as favorite by your neighbors
- FW: Weight applied to favorite movie = 5
- D(M): Number of times movie M has been marked as not liked by your neighbors
- DW: Weight applied to not liked movie = -5
