D'altra parte stiamo parlando di 4,88 metri di lunghezza contro 4,33. each dimension, specified as a positive vector. is inefficient. pdist = torch.nn.PairwiseDistance(p=2) dist1 = pdist(out, subgraphout) distance = sokalsneath function documentation). So I'm inclined to say that they're not expected to be the same. xt, i.e., This would result in distfun A distance metric is a function that defines a distance between The The standardized But it won't raise if XB equals XA and XB is not XA, and it would be too costly to check element-wise equality between XA and XB. Size of the Gram matrix in megabytes, specified as a positive scalar or boolean vectors. However, from a statistical point of vue, maybe a special case could be done in cdist when XB is XA, returning squareform(pdist(XA)), because when XB is XA, XB and XA are the same set of sample from the distribution and therefore var and cov should be estimated on XA only. cache argument.
