WebAug 29, 2024 · Yes, In triplet loss function weights should be shared across all three networks, i.e Anchor, Positive and Negetive.In Tensorflow 1.x to achieve weight sharing you can use reuse=True in tf.layers.. But in … 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
