Archive of my development work for the 2009 GitHub Contest, circa 2009.
This project provided code to generate a solution (results.txt) to the github contest August 2009.
I participated in this contest as a learning exercise for both programming languages (ruby and then Objective-c) and technology (collaborative filtering).
See my archived write-ups here and here for details of the methods used and finding from the data.
I think I came in 13th position.
A k-nearest neighbor recommender system was developed in Ruby, but was then abandoned because of speed issues.
A new KNN based recommender system was then developed in Objective-C.
Code was not saved.
A version of the ruby code was captured on internet archive.
