WebMay 28, 2024 · Edit: Actually I now understand that you’re trying to compute the cosine similarity of a sequence of word embeddings with another sequence of word embeddings. I believe the above suggestion of taking the mean could be useful. loss2 = 1- (my_loss (torch.mean (torch.stack (embedding_prime), 0), torch.mean (torch.stack … WebFeb 21, 2024 · 6. Cosine similarity: F.cosine_similarity. Staying within the same topic as in the last point - calculating distances - euclidean distance is not always the thing you need. When working with vectors, usually the cosine similarity is the metric of choice. PyTorch has a built-in implementation of cosine similarity too.

WebDec 14, 2024 · Now I want to compute the cosine similarity between them, yielding a tensor fusion_matrix of size [batch_size, cdd_size, his_size, signal_length, signal_length] where entry [ b,i,j,u,v ] denotes the cosine similarity between the u th word in i th candidate document in b th batch and the v th word in j th history clicked document in b th batch. WebNov 28, 2024 · What is the difference between cosine similarity functions torch.nn.CosineSimilarity and torch.nn.functional.cosine_similarity? The two are effectively the same and they can be used essentially interchangeably. In particular, they both support backpropagation in the same way.
