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 …
Gaussian complexity is a similar complexity with similar physical meanings, and can be obtained from the Rademacher complexity using the random variables instead of , where are Gaussian i.i.d. random variables with zero-mean and variance 1, i.e. (,).
