It seems especially convenient for modelling suddenly-encountered situational differences, like ‘the tank you just hijacked is bigger than other vehicles; gain 2 […]


Pairwise similarity matrix between a set of vectors in PyTorch

Let’s suppose that we have a 3D PyTorch tensor, where the first dimension represents the batch_size, as follows: import torch import torch.nn as nn x = torch.randn(32, 100, 25) That is, for each i, x[i] is a set of 100 25-dimensional vectors. I would like to compute the similarity (e.g., the cosine similarity — but […]
