Webbför 2 dagar sedan · Triplet-wise learning is considered one of the most effective approaches for capturing latent representations of images. The traditional triplet loss (Triplet) for representational learning samples a set of three images (x A, x P, and x N) from the repository, as illustrated in Fig. 1.Assuming access to information regarding whether … Webb21 sep. 2024 · CL in fundus image based DR grading is even rarer. To address the aforementioned issues, we propose a lesion-based contrastive learning approach for fundus image based DR grading. Instead of using entire fundus images, lesion patches are taken as the input for our contrastive prediction task.

WebbA promising solution is contrastive learning, which attempts to learn domain-invariant representations by exploiting rich semantic relations among sample-to-sample pairs from different domains. A simple approach is to pull positive sample pairs from different domains closer while pushing other negative pairs further apart.
