Pretraining with Contrastive Sentence Objectives Improves Discourse Performance of Language Models (2020.acl-main)
Copied to clipboard
| Challenge: | Recent models for unsupervised representation learning of text have put little focus on discourse-level representations. |
| Approach: | They propose an inter-sentence objective for pretraining language models that models discourse coherence and the distance between sentences. |
| Outcome: | The proposed model outperforms the BERT-Large model on the discourse representation benchmark DiscoEval and yields gains of 2%-6% absolute even for tasks that do not explicitly evaluate discourse. |

SLM: Learning a Discourse Language Representation with Sentence Unshuffling (2020.emnlp-main)
Copied to clipboard
| Challenge: | Recent models for learning discourse language representations focus on bottom or top-level representations, but they do not capture intermediate-size structures in natural languages such as sentences and the relationships among them. |
| Approach: | They propose a new objective for learning a discourse language representation in a self-supervised manner by shuffling the sequence of input sentences and training a hierarchical transformer model to reconstruct the original ordering. |
| Outcome: | The proposed model improves the original BERT model on downstream tasks by large margins. |

ConSERT: A Contrastive Framework for Self-Supervised Sentence Representation Transfer (2021.acl-long)
Copied to clipboard
| Challenge: | Existing BERT-based pre-trained language models achieve high performance on many downstream tasks, but native derived sentence representations are collapsed and thus poor performance on semantic textual similarity (STS) tasks. |
| Approach: | They propose a framework for self-supervised Sentence Representation Transfer that adopts contrastive learning to fine-tune BERT in an unsupervised way. |
| Outcome: | The proposed framework improves on the BERT-derived representations by 8% on STS datasets and shows robustness in data scarcity scenarios. |
