A concentration measure is a way to bound the probability for the event in which the sum of random variables is "far" from the sum of their means. This allows us to, on the one hand, decrease the runtime of the Making statements based on opinion; back them up with references or personal experience. Why weren't the marines in "Aliens" properly briefed on the cooling towers before they went in? Thus if \(\delta \le 1\), we The company assigned the same $2$ tasks to every employee and scored their results with $2$ values $x, y$ both in $[0, 1]$. We and our partners use cookies to Store and/or access information on a device. Using Chernoff bounds, find an upper bound on P(Xn), where pIs Chernoff better than chebyshev? Di@ '5 Suppose that we decide we want 10 times more accuracy. Hoeffding and Chernoff bounds (a.k.a "inequalities") are very common concentration measures that are being used in many fields in computer science. The print version of the book is available through Amazon here. This bound is quite cumbersome to use, so it is useful to provide a slightly less unwieldy bound, albeit one that sacri ces some generality and strength. It is a concentration inequality for random variables that are the sum of many independent, bounded random variables. compute_shattering: Calculates the shattering coefficient for a decision tree. One way of doing this is to define a real-valued function g ( x) as follows: \begin{align}%\label{} site design / logo 2021 Stack Exchange Inc; user contributions licensed under cc by-sa.
