WebApr 1, 2024 · In this section we perform a controlled comparison of our proposal with some of the most commonly used ranking losses: triplet, semi hard and batch hard, contrastive-batch hard and the three methods for triplet selection: hierarchical tree [32], 100k IDs [18] and SPL [37]. We avoid extra variables (e.g. augmentation, other architectures, etc ...

This allows us to determine which triplets in the batch are Semi-Hard; if they are we keep num_hard of them, populating the rest of the batch with other random triplets. By padding with random triplets, we allow … WebNov 29, 2024 · Now, for each sample a in the batch, we can select the hardest positive and the hardest negative samples within the batch when forming the triplets for computing the loss, which we call Batch Hard" So at the moment I have a Python generator (for use with model.fit_generator in Keras) which produces batches on the CPU. ford premium care warranty canada
