WebThis notion is formalized by the incoherence condition [3] as deﬁned in Section II. In particular the incoherence condition is satisﬁed with high probability if M= U 0VT with U0and V0uniformly random orthogonal matrices. Out of the m nentries of M, a subset E [ ] (the user/movie pairs for which a rating is available) is revealed. http://www.emijournal.net/dcyyb/ch/reader/view_abstract.aspx?file_no=20240527015&flag=1

Webincoherence condition (3) is restrictive and unintuitive. In many cases, 1 is as large as 2 0r, so previous results require O(nr2polylog(n)) observations even if 0 = O(1). In the following main theorem of the paper, we show that the joint incoherence is not necessary. The theorem only requires the weak incoherence condition. Theorem 1. Web–Step 3(b): incoherence condition of the leave-one-out iterates. The fact that Z t+1 and Z t+1;(l) are exceedingly close motivates us to control the incoherence of Z Z \ instead, for focus barry
