For t = 1, 2, . . , let T (I, θt−1 , θt−1 ) . T (I, θt−1 , θt−1 ) θt := Then k v1 − θt 2 ≤ λ−2 i 2λ21 i=2 λ 2 v2 θ 0 · λ 1 v1 θ 0 2t+1 . That is, repeated iteration of (6) starting from θ0 converges to v1 at a quadratic rate. To obtain all eigenvectors, we may simply proceed iteratively using deflation, executing the power method on T − j λj vj⊗3 after having obtained robust eigenvector / eigenvalue pairs {(vj , λj )}. Proof. Let θ0 , θ1 , θ2 , . . be the sequence given by θ0 := θ0 and θt := T (I, θt−1 , θt−1 ) for t ≥ 1.

Hk ) ∼ Dir(α), and then conditioned on h, we draw x1 , x2 , . . , for each xt , we independently sample a topic j according to h and then sample xt according to μj ). Again, we encode a word xt by setting xt = ei iff the t-th word in the document is i. The parameter α0 (the sum of the “pseudo-counts”) characterizes the concentration of the distribution. , the limiting density has, with probability 1, exactly one entry of h being 1 and the rest are 0). At the other extreme, if α = (c, c, . .
