Consider a matrix factorization problem of the form $\mathbf{X}=\mathbf{W Z}^{\top}$ to obtain an item-user recommender system where $x_{i j}$ denotes the rating given by $j^{\text {th }}$ user to the $i^{\text {th }}$ item . We use Root mean square error (RMSE) to gauge the quality of the factorization obtained. Select the correct option.
A. Given a new item and a few ratings from existing users, we need to retrain the already trained recommender system from scratch to generate robust ratings for the user-item pairs containing this item.
B. Regularization terms for $\mathbf{W}$ and $\mathbf{Z}$ in the form of their respective Frobenius norms are added to the RMSE so that the resulting objective function becomes convex.
C. For obtaining a robust factorization of a matrix $\mathbf{X}$ with $D$ rows and $N$ elements where $N \ll D$, the latent dimension $\mathrm{K}$ should lie somewhere between $D$ and $N$.
D. None of the other options are correct.
