WebMiners. Mining functions take a batch of n embeddings and return k pairs/triplets to be used for calculating the loss: Pair miners output a tuple of size 4: (anchors, positives, anchors, negatives). Triplet miners output a tuple of size 3: (anchors, positives, negatives). Without a tuple miner, loss functions will by default use all possible ... WebPairwiseDistance. Computes the pairwise distance between input vectors, or between columns of input matrices. Distances are computed using p -norm, with constant eps …

WebJul 12, 2024 · For 32bits floats the behaviour is rather erroneous, as the minimum of the distance is not between a vector and itself. In 16 bits while we do get the erroneous value of 0 when comparing c and c + 1e-6, the correct minimum is present, but we have a larger set of correct ones.. Expected behavior WebDec 4, 2024 · Since the documentation doesn't give examples on how to use the distance's forward function.
