I am working on algorithms for collaborative filtering (CF). As part of this work, I want to compare a new algorithm to previous approaches to the problem. I am also surveying the most important methods and publications in publications. So far I have skimmed through around 50 articles, but I have difficulty in pin-pointing the most relevant/interesting.
I want to test my CF-algorithm against a set of other CF-algorithms, both some simple baseline methods and some of the newer methods. Which methods should I compare my algorithm to?
I am going to implement (or find implementations) as many of these as possible during the next couple of months, so it should be possible to get around a fair bit of different methods.
