Cluster-wise triplet loss function
Web- Proposed high-resolution voxel-based instance-wise semantic segmentation method from the RGB-D dataset. - Applied triplet loss function to cluster the object by minimizing the features of the same object and maximizing the others. WebDec 30, 2024 · As shown in the paper, the best results are from triplets known as "Semi-Hard". These are defined as triplets where the negative is farther from the anchor than the positive, but still produces a positive loss. To efficiently find these triplets we utilize online learning and only train from the Semi-Hard examples in each batch.

Based on the definition of the loss, there are three categories of triplets: WebFurthermore, we design a quantization objective function based on the principle of preserving triplet ordinal relation to minimize the loss caused by the continuous relaxation procedure. The comparative RS image retrieval experiments are conducted on three publicly available datasets, including UC Merced Land Use Dataset (UCMD), SAT-4 and SAT-6.
WebIn this paper, we propose a simple class-wise triplet loss based on the intra/inter-class distance metric learning which can largely reduce the number of the possible triplets to … WebMar 31, 2024 · Figures 3 and 4 show the F1 score and k-nearest recall score using triplet loss, intra-class loss (Bai et al. 2024), global loss (Vijay Kumar et al. 2015) and the proposed method. It is worth mentioning that our method provides significant performance margin when compared with triplet loss, and performs at par with intra-class-based …

Inspired by them, we have proposed … WebClassical pair-based loss functions. Siamese network [6] is a representative pair-based method that learns an em-bedding via contrastive loss. It encourages samples from a positive pair to be closer, and pushes samples from a neg-ative pair apart from each other, in the embedding space. Triplet loss was introduced in [10] by using triplets as ...
