DeCLUTR: Deep Contrastive Learning for Unsupervised Textual Representations [PDF]

open access: yesAnnual Meeting of the Association for Computational Linguistics, 2020
Sentence embeddings are an important component of many natural language processing (NLP) systems. Like word embeddings, sentence embeddings are typically learned on large text corpora and then transferred to various downstream tasks, such as clustering ...

The Contrastive Study of the Conjunction ‘and’ in English and Armenian

open access: yesTranslation Studies: Theory and Practice, 2021
In linguistics the structuring role of conjunctions is emphasized, whereas its pragmatic and contrastive study is often foregrounded. Conjunction may be prerequisite for contrastive study. The present research is mainly aimed at establishing semantic

Unsupervised Dense Retrieval with Relevance-Aware Contrastive Pre-Training [PDF]

open access: yesAnnual Meeting of the Association for Computational Linguistics, 2023
Dense retrievers have achieved impressive performance, but their demand for abundant training data limits their application scenarios. Contrastive pre-training, which constructs pseudo-positive examples from unlabeled data, has shown great potential to ...

ConFEDE: Contrastive Feature Decomposition for Multimodal Sentiment Analysis

open access: yesAnnual Meeting of the Association for Computational Linguistics, 2023
Multimodal Sentiment Analysis aims to predict the sentiment of video content. Recent research suggests that multimodal sentiment analysis critically depends on learning a good representation of multimodal information, which should contain both modality ...

UNIMO: Towards Unified-Modal Understanding and Generation via Cross-Modal Contrastive Learning [PDF]

open access: yesAnnual Meeting of the Association for Computational Linguistics, 2020
Existed pre-training methods either focus on single-modal tasks or multi-modal tasks, and cannot effectively adapt to each other. They can only utilize single-modal data (i.e., text or image) or limited multi-modal data (i.e., image-text pairs).

Mitigating Hallucinations and Off-target Machine Translation with Source-Contrastive and Language-Contrastive Decoding [PDF]

open access: yesConference of the European Chapter of the Association for Computational Linguistics, 2023
Hallucinations and off-target translation remain unsolved problems in MT, especially for low-resource languages and massively multilingual models. In this paper, we introduce two related methods to mitigate these failure cases with a modified decoding ...

Improving Contrastive Learning of Sentence Embeddings from AI Feedback [PDF]

open access: yesAnnual Meeting of the Association for Computational Linguistics, 2023
Contrastive learning has become a popular approach in natural language processing, particularly for the learning of sentence embeddings. However, the discrete nature of natural language makes it difficult to ensure the quality of positive and negative ...

Chackelis Lemchenas, a contrastive linguist before contrastive linguistics

open access: yesPhilologia Estonica Tallinnensis, 2023
The article explores the views of Chackelis Lemchenas (1904– 2001) on teaching Lithuanian to speakers of other languages. As a prominent linguist, experienced practitioner, and a multilingual person, he proposed ideas that are compatible with the principles of contrastive linguistics already in the 1920s.

Supporting Clustering with Contrastive Learning [PDF]

open access: yesNorth American Chapter of the Association for Computational Linguistics, 2021
Unsupervised clustering aims at discovering the semantic categories of data according to some distance measured in the representation space. However, different categories often overlap with each other in the representation space at the beginning of the ...
