Through simulation we illustrate issues with model fitting techniques that depend on matrix factorization. Far from hypothetical, we have encountered these issues in our experiences with "big data" prediction problems. both L1 and L2 penalties; see [8]) which were tuned for test set accuracy (log likelihood).
