    Hi, I want to ask whether “ratings_t = tf.matmul(Uk, Si)” should be “ratings_t = tf.matmul(Su, Si)”?

    Compute reduced matrices

    Sk = tf.diag(St)[0:nb_factors, 0:nb_factors]
    Uk = Ut[:, 0:nb_factors]
    Vk = tf.transpose(Vt)[0:nb_factors, :]

    Hi, I just want to ask , there should be a transpose operation when calculating the Vk matrix. Or else the shape of ratings would be incorrect.
