Problem 4.2 (b) and (d)

[Liang-Ting Jiang]

For clustering the latent factor matrix in Problem 4.2 (b) and (d), what's the dimension of the latent factor k we should use? Thanks.

Please use K = 10

Thanks,

Btw, are we supposed different results every time we run ALSMatrixFactorization (even with the same parameters)?

The result will be different. The initialization of the U, V matrices are random.
