WebOct 19, 2024 · In these examples I use a really large margin, since the embedding space is so small. A more realistic margins seems to be between 0.1 and 2.0. from torch import nn import torch model = nn.Embedding (10, 10) #from online_triplet_loss.losses import * labels = torch.randint (high=10, size= (5,)) # our five labels embeddings = model (labels) print ... WebMar 19, 2024 · Triplet loss with semihard negative mining is now implemented in tf.contrib, as follows: triplet_semihard_loss( labels, embeddings, margin=1.0 ) where: Args: labels: 1 … WebJul 11, 2024 · The triplet loss is a great choice for classification problems with N_CLASSES >> N_SAMPLES_PER_CLASS. For example, face recognition problems. The CNN architecture we use with triplet loss needs to be cut off before the classification layer. In addition, a L2 normalization layer has to be added.
