WebDec 19, 2024 · Fisher–Yates shuffle Algorithm works in O (n) time complexity. The assumption here is, we are given a function rand () that generates a random number in O (1) time. The idea is to start from the last element and swap it with a randomly selected element from the whole array (including the last). Now consider the array from 0 to n-2 (size ... WebMar 7, 2024 · Hi, hope I can get some help here. I want to implement unsupervised contrastive learning model MoCo in TF2, but I have no idea how to implement the essential trick mentioned in the paper - Shuffling BN. I think I understand what shuffling BN does, but I don’t know any APIs to fetch different data slices from each GPU, shuffle them, and send …
