Consider the following on-line learning method to estimate the expected value of a real-valued random variable X. We begin with an initial estimate µ0, and then for t = 1, 2, . . . , Obtain xt as an independent identical distribution (i.i.d) sample of X, and Revise our ... at step t. Assume X is normally distributed with mean µ and variance σ 2 . If we choose αt = 1 t , then E[µt ] is

S ∉ S is always true as {A} ∉ {A} so S1 can have elements and sets can exist as elements in a set, so why does S2 doesn’t exists either?
