    Description

      For random sampler with fraction, like BernoulliSampler and PoissonSampler, Gap based random sampler could exploit O(k) sample implementation instead of previous O(n) sample implementation, it should perform better while sample fraction is very small. This blog describes more detail about gap based random sampler.
