I was trying to tune CoClustering with cross validation, but found that it always gave higher RMSE than Baseline. The performance decreased along with the increase of either NumUserClusters or NumItemClusters (so I ended up with both equal to 1). It seems like overfitting, but I could not find a regularization parameter.
