WebMar 18, 2024 · Finally, another useful application of the triplet loss function is in the recommendation systems. For example, suppose we want to recommend similar products to customers based on their previous purchases. In that case, we can train a similarity network using the triplet loss that computes the similarity of products. 5. Challenges Here the network is trained (using a contrastive loss) to output a distance which is small if the image belongs to a known person and large if the image belongs to an unknown person. However, if we want to output the closest images to a given image, we want to learn a ranking and not just a similarity. A … See more Triplet loss is a loss function for machine learning algorithms where a reference input (called anchor) is compared to a matching input (called positive) and a non-matching input (called negative). The distance from the anchor to the … See more In computer vision tasks such as re-identification, a prevailing belief has been that the triplet loss is inferior to using surrogate losses (i.e., … See more • Siamese neural network • t-distributed stochastic neighbor embedding • Learning to rank See more
