This paper describes one possible way to solve task "Who rated what?" of the KDD CUP 2007. The proposed solution is a history-based model that predicts whether a user will vote a given movie. Key points to our approach are (1) the estimation of the model baseline, (2) the definition of the explanatory variables and (3) the mathematical model form. Given the binary outcome of the problem, the estimation of the true baseline (ratio of 1's in the test data) is critical in order to correctly make… CONTINUE READING
