WebSuppose I have only two data describing a normal distribution: the mean $\mu$ and variance $\sigma^2$. I want to use a computer to randomly sample from this distribution such that I respect these two statistics. It's pretty obvious that I can handle the mean by simply normalizing around 0: just add $\mu$ to each sample before outputting the sample. Web22 de jan. de 2024 · 2. if you really want a given sample to have a mean of zero and variance of 1 (as opposed to being sampled from a distribution with zero mean and unit variance) then you can just transform it to make it so, e.g.: x = torch.randn (4,3) x -= x.mean () x /= x.std () this sort of thing can be useful.
