Today I read a paper titled “Movie Recommendation Systems Using An Artificial Immune System”
The abstract is:
We apply the Artificial Immune System (AIS) technology to the Collaborative Filtering (CF) technology when we build the movie recommendation system.
Two different affinity measure algorithms of AIS, Kendall tau and Weighted Kappa, are used to calculate the correlation coefficients for this movie recommendation system.
From the testing we think that Weighted Kappa is more suitable than Kendall tau for movie problems.
