We then search them from {0.01, 0.05, 0.1, 0.5, 1} via cross-validation. We will show the experimental results later for different values of fold number. For the results reported in the paper, we set it to 4. An additional In this document, we will also provide sensitivity experiments about this parameter. We then output a ranked list of each user based the predicted rating. The HR and nDCG are defined as follows.
