We present a refined analysis of the classic Count-Sketch streaming heavy hitters algorithm [CCF02]. Count-Sketch uses O (k log n) linear measurements of a vector x in R^n to give an estimate x' of x. The standard analysis shows that this estimate x' satisfies x'-x _infty^2 < x_tail _2^2 / … gaming is good for your health https://langhosp.org

Show that, P ( X ≥ c) ≤ e − c t + t 2 2 for c &gt; 0 and for all t in R. I found that P ( X ≥ c) = Φ ( − c) where Φ ( x) = ∫ − ∞ x ϕ ( u) d u is the cdf of a standard normal variable. I understand that the upper bound is in the form of mgf of normal distribution.

WebbFor the purpose of illustration we apply these results to some standard problems in learning theory, vector valued concentration, the generalization of PCA and the method of Rademacher complexities. Over the last twenty years the latter method ([1], [5]) has been successfully used to prove gener-alization bounds in a variety of situations. In probability theory, concentration inequalities provide bounds on how a random variable deviates from some value (typically, its expected value). The law of large numbers of classical probability theory states that sums of independent random variables are, under very mild conditions, close to their expectation with a large probability. Such sums are the most basic examples of random variables concentrated around their mean. Recent results show that such behavior is shared by o…
