Collaborative Filtering With Likes and Dislikes

Collaborative Filtering With Likes and Dislikes

Came across several interesting articles on collaborative filtering over the weekend and this one is particularly interesting.

This algorithm is able to deal with a binary case. i.e. If I like this this this and dislike that that that, what are the chances that someone who has the same taste as me like something else.

I will modify it a little to use it with groups of demographies and test it to see if it improves CPA in the real world.

Will post more after research.
