torch.std_mean — PyTorch 1.10.1 documentation
pytorch.org › docs › stable
A tuple (std, mean) containing the standard deviation and mean. torch. std_mean (input, unbiased) Calculates the standard deviation and mean of all elements in the input tensor. If unbiased is True, Bessel’s correction will be used. Otherwise, the sample deviation is calculated, without any correction. Parameters. input – the input tensor.

torch.mean — PyTorch 1.10.1 documentation
https://pytorch.org/docs/stable/generated/torch.mean.html
torch. mean (input, dim, keepdim = False, *, dtype = None, out = None) → Tensor Returns the mean value of each row of the input tensor in the given dimension dim.If dim is a list of dimensions, reduce over all of them.. If keepdim is True, the output tensor is of the same size as input except in the dimension(s) dim where it is of size 1. Otherwise, dim is squeezed (see …

Sep 29, 2019 · If we multiply the result by sigma, and add mu we will set the result to have mean=mu and stdv=sigma. Pytorch doesn't do any of these - instead it applies the standard score, but not with the mean and stdv values of X (the image to be normalized) but with values that are the average mean and average stdv over a large set of Imagenet images.

torch.median — PyTorch 1.10.1 documentation
pytorch.org › docs › stable
torch.median(input) → Tensor. Returns the median of the values in input. Note. The median is not unique for input tensors with an even number of elements. In this case the lower of the two medians is returned. To compute the mean of both medians, use torch.quantile () with q=0.5 instead. Warning.
torch.nanmean — PyTorch 1.10.1 documentation
https://pytorch.org/docs/stable/generated/torch.nanmean.html
torch.nanmean¶ torch. nanmean (input, dim = None, keepdim = False, *, dtype = None, out = None) → Tensor ¶ Computes the mean of all non-NaN elements along the specified dimensions.. This function is identical to torch.mean() when there are no NaN values in the input tensor. In the presence of NaN, torch.mean() will propagate the NaN to the output whereas torch.nanmean() …
