Siamese networks triplet loss
WebSiamese Networks: Siamese networks are a type of neural network architecture that have two identical sub-networks which share the same parameters. ... Examples of metric learning approaches include contrastive loss, triplet loss, and quadruplet loss. ... WebBoth PCA and neural networks with triplet loss turned out to be effective for this task. In particular, we found that neural networks are beneficial for small dimensionalities of between 6 and 12. Such small dimensions allow for indexing by simple nearest neighbor trees, which could be the foundation of fast content-based audio retrieval in large …
