Triplet network 预训练
WebJun 8, 2024 · Online Triplet Mining. Triplet network is tricky to be trained quickly and effectively. A main reason is the randomness in choosing training triplets online. As discussed above, the loss becomes zero if the input triplet is already predictable, in which the difference of the two distances already reaches alpha and the loss vanishes. WebIn this tutorial, I show you how you can leverage triplet loss to train a neural network to map MNIST digits to a vector space where classifying between digi...

Siamese and triplet networks are useful to learn mappings from image to a compact Euclidean space where distances correspond to a measure of similarity [2]. Embeddings trained in such way can be used as features vectors for classification or few-shot learning tasks.
