Holders inequality rademacher average
NettetRademacher complexity is a measure of the richness of a class of real-valued functions. In this sense, it is similar to the VC dimension. In fact, we will establish a uniform deviation bound in terms of Rademacher complexity, and … NettetThe Rademacher’s complexity measures how well correlated the most-correlated hypothesis is to a random labeling of points in S. The Rademacher’s complexity depends on the distribution D. We need to know Din order to compute R m(l H). This leads to the so-called empirical Rademacher’s complexity. 3 Empirical Rademacher Average

Let ϵ = ( ϵ 1,.., ϵ n) be a Rademacher sequence, i.e. P r o b ( ϵ i = 1) = P r o b ( ϵ i = − 1) = 1 2 . It is known that for all p ≥ 2, NettetRademacher复杂度是求损失函数的多样性，损失函数是定义集合Z到区间 [a,b]的映射；但实际上我们第一节分析的过程当中，区间是被限定在 [0,1]的。 所以我们要推出两者的关系，需要统一下目标：是求函数集合 G 的多样性，且该函数的值域全都是 \ {-1,+1\} 。 于是有以下推论： \mathfrak {R}_m (G)\le \sqrt {\frac {2\log\Pi_G (m)} {m}}\\ 证明主要用 …
