Ordered contrastive learning
WebMar 25, 2024 · The proposed method leverages both labeled and unlabeled data pools and selects samples from clusters on the feature space constructed via contrastive learning. Experimental results demonstrate that the proposed method requires a lower annotation budget than existing active learning methods to reach the same level of accuracy. PDF … WebDec 15, 2024 · Contrastive Learning states that for any positive pairs x1 and x2, the respective outputs f(x1) and f(x2) should be similar to each other and for a negative input x3, f(x1) and f(x2) both should be dissimilar to f(x3). ... In order to validate the richness of the representations learnt by CPC, a linear evaluation protocol is used. A linear ...

WebSep 2, 2024 · Contrastive learning achieves this by using three key ingredients, a positive, anchor, and negative (s) representation. To create a positive pair, we need two examples that are similar, and for a negative pair, we use a third example that is not similar. But in self-supervised learning, we don’t know the labels of the examples. WebApr 12, 2024 · Building an effective automatic speech recognition system typically requires a large amount of high-quality labeled data; However, this can be challenging for low-resource languages. Currently, self-supervised contrastive learning has shown promising results in low-resource automatic speech recognition, but there is no discussion on the quality of …

Webfeatures are more important for transfer learning [55], and feature suppression can occur [4] just as with supervised learning [10, 16]. Combining contrastive learning with an auto-encoder has also been considered [28], but was found to harm representation of some features in order to avoid suppression of others. simpson its hangersWebDec 31, 2024 · This paper proposes Contrastive LEArning for sentence Representation (CLEAR), which employs multiple sentence-level augmentation strategies in order to learn a noise-invariant sentence representation.
