| Outcome: | The proposed model outperforms models trained on large, unrelated datasets on downstream NLP tasks. |
ChineseBERT: Chinese Pretraining Enhanced by Glyph and Pinyin Information (2021.acl-long)
Copied to clipboard
| Challenge: | ChineseBERT model incorporates glyph and pinyin information of Chinese characters into pretraining . proposed model achieves new performance boost over baseline models with fewer training steps . |
| Approach: | They propose a ChineseBERT model that incorporates glyph and pinyin information into pretraining . the glyph embedding is obtained based on different fonts of a character, and the pinyink embeddment characterizes the pronunciation of Chinese characters. |
| Outcome: | The proposed model achieves new performance boosts over baseline models with fewer training steps. |
ERNIE-Doc: A Retrospective Long-Document Modeling Transformer (2021.acl-long)
Copied to clipboard
| Challenge: | Existing models for document-level language pretraining are not suitable for long documents due to their quadratically increasing memory and time consumption. |
| Approach: | They propose a document-level language pretraining model based on Recurrence Transformers. |

Agustín Lucas, Alexis Baladón, Victoria Pardiñas, Marvin Agüero-Torales, Santiago Góngora, Luis Chiruzzo
| Challenge: | Low-resource languages suffer from a vicious circle: data is needed to build tools, but available text is scarce. |
| Approach: | They propose to use a grammar-based system to generate Spanish text and syntactically transfer it to Guarani to boost its performance. |
| Outcome: | The proposed system outperforms existing models by pretraining models with synthetic text. |
What do Large Language Models Learn beyond Language? (2022.findings-emnlp)
Copied to clipboard
| Challenge: | Pretraining on text confers models with useful ‘inductive biases’ for non-linguistic reasoning. |
| Approach: | They investigate whether pre-training on text confers these models with helpful ‘inductive biases’ for non-linguistic reasoning. |
| Outcome: | The proposed models outperform non-pretrained models on 19 non-linguistic tasks and show that they retain inductive biases even when training on multi-lingual text and computer code. |
ProCQA: A Large-scale Community-based Programming Question Answering Dataset for Code Search (2024.lrec-main)
Copied to clipboard
| Challenge: | Existing approaches to code question answering use bi-modal and unimodal pretraining to align text and code representations. |
| Approach: | They propose a modality-agnostic contrastive pre-training approach to improve alignment of text and code representations of current code language models. |
| Outcome: | The proposed model exhibits significant performance improvements across a wide range of code retrieval benchmarks. |

Jiandong Shao, Raphael Tang, Crystina Zhang, Karin Sevegnani, Pontus Stenetorp, Jianfei Yang, Yao Lu
| Challenge: | Existing research suggests that multilingual large language models can achieve impressive cross-lingual understanding despite largely monolingual pretraining. |
| Approach: | They compare a monolingual-only corpus with a standard web corpus that removes all multilingual documents and then retrain the models from scratch under controlled conditions. |
| Outcome: | The results show that removing bilingual data causes translation performance to drop 56% in BLEU, whereas code-switching contributes minimally. |
