categorical.sample()方法在机器学习中有着广泛的应用,例如在训练神经网络时,我们经常需要从一个分布中进行采样,categorical.sample()方法可以帮助我们完成这个任务。另外,在蒙特卡洛方法和马尔科夫链蒙特卡洛方法中,categorical.sample()方法也是必不可少的工具。 5. 注意事项 在使用categorical.sample()方法时需要注意,输...
🐛 Bug Categorical.sample(shape) calls shape times torch.multinomial(probas, 1, True). This is slow when we want to get many samples from a large number of classes. To Reproduce Steps to reproduce the behavior: import torch sampling = tor...
🐛 Bug When sampling from a torch.distributions.Categorical distribution initialized with a few distributions (e.g. 2 distributions each with 2**16 categories) the sample() functions allocates unnecessary huge amount of memory. To Reprodu...

Although the KruskalWallis test has been widely used to analyze ordered categorical data, power and sample size methods for this test have been investigated to a much lesser extent when the underlying multinomial distributions are unknown. This article generalizes the power and sample size procedures ...
