n*rand(1,k)最后由于你取列那肯定是要整数吧，所以 ceil（n*rand(1,k)）向上取整。也就是说，你 ind 产生的是n个类中选k个作为初始分类种子 对这句话解释的非常详细了吧
Seeding the random number generator means initializing it to a certain status. Seeding inside the loop means, that all "random" numbers created inside the loop will be the same in each iteration: ThemeCopy for i = 1:3 rand('seed', 1); disp(rand); end Result: 0.51291 0.51291 0.51291 Th...
Suppose the former—that is, there is an element in X that is not in Y. That means that X must overlap with at least one other partition class of B—that is, X overlaps with at least two partition classes of B. Thus, |V|>|A|⇒|A||V|<1 By Theorem 3.5 |V|≥|B|⇒|B...
So we test that the output values of dlib::rand are not // changed in this test. { dlib::rand rnd; std::vector<uint32> out; for (int i = 0; i < 30; ++i) { out.push_back(rnd.get_random_32bit_number()); } const std::vector<uint32> expected = { 725333953,251387296,...
You are producing 1e8 numbers, so it is possible that there's not a single 0 in your sample. cuda side never produces 0-s (it is not supposed to). Using your fix for cuda will introduce subtle distortions, but whatever, the definition of what it means to generate uniformly distributed...
