WebJul 16, 2024 · As a distance metric L2 distance or (1 - cosine similarity) can be used. The objective of this function is to keep the distance between the anchor and positive smaller than the distance between the anchor and negative. Model Architecture: The idea is to have 3 identical networks having the same neural net architecture and they should share weights. WebCosineSimilarity class torch.nn.CosineSimilarity(dim=1, eps=1e-08) [source] Returns cosine similarity between x_1 x1 and x_2 x2, computed along dim. \text {similarity} = \dfrac {x_1 \cdot x_2} {\max (\Vert x_1 \Vert _2 \cdot \Vert x_2 \Vert _2, \epsilon)}. similarity = … WebLearn about PyTorch’s features and capabilities.
