False negative contrastive learning

WebOct 9, 2024 · This work presents a supervised contrastive learning framework to learn a feature embedding robust to changes in viewpoint, by effectively leveraging multi-view data, and proposes a new approach to use classifier probabilities to guide the selection of hard negatives in the contrastive loss. Highly Influenced. WebMay 11, 2024 · 4.2 Mine and Utilize Hard Negative Samples in RL. As mentioned, hard negative samples, i.e., the pairs with similar representation but different semantics are the key to efficient contrastive learning [ 21 ]. However, how to mine such samples from the data is still a challenging problem in the literature.
