Product distribution learning with imperfect advice

We revisit this problem when the learner is also given as advice the parameters of a product distribution Q. We show that there is an efficient algorithm to learn P within TV distance εthat has sample complexity O(d1 η/ε2), if p q 1 < εd0.5 Ω(η). Here, p and q are the mean vectors of P and Q respectively, and no bound on p q 1 is known to the algorithm a priori.
