NettetComparing the exponent, it is easy to see that for > 1/6, Hoeffding’s inequality is tighter up to a certain constant factor. However, for smaller , Chernoff bound is significantly better than Hoeffding’s inequality. Before proving Theorem 2 in Section 3, we see a practical application of Hoeffding’s inequality. Nettet24. apr. 2024 · sample mean; and this is a legitimate process of develop bounds on the sample mean conditioned on the assumption of the population mean. To develop an optimal concentration inequality to replace Hoeffding’s inequality in UCB algo-rithms it is therefore legitimate that we ask the same question that Hoeffding’s inequality answers:

However the question's set up involves constants, for example, the statement Pr( Eout ≥ ϵ) ≤ 2e − 2nϵ2 doesn't even make sense as Eout is a constant.
