Web6 Feb 2015 · I was hoping someone could help point me in the right direction to create a vector in R, containing a defined amount of randomly generated numbers. Web9 May 2024 · A series (that is, a sum) of Rademacher distributed variables can be regarded as a simple symmetrical random walk where the step size is 1. Contents 1 Mathematical …
WebLet X1, …, Xn be i.i.d. Rademacher random variables. That is, Pr(Xi = 1) = Pr(Xi = − 1) = 1 / 2. I was wondering if the following argument is true: Eexp(C ⋅ ( n ∑ i = 1Xi)4 /n3) = 1 + O(1 / n), where C ≥ 0 is a constant. I did some numerical simulations and the results validated this argument. I would appreciate it if anyone can give a proof. Web13 Apr 2024 · The proof of the theorem in the present paper closely follows the scheme in , the novelty at each step being of one of the following two types: either all the argument is obtained from the one in automatically via the replacement of \(\sum_{j=1}^\infty\) by \(\sum_{j=1}^{k}\) everywhere, or we still need to make additional estimates related to …
Webwe first generalize Rademacher complexity to weighted sets. While Rademacher complexity is defined as the maximum of the sum of Rademacher variables over a set, weighted Rademacher complexity also accounts for the weight of each element in the set. Just like Rademacher complexity is related to the size of the set, we show that weighted …
