ControlMath: Controllable Data Generation Promotes Math Generalist Models

EMNLP 2024main

Utilizing large language models (LLMs) for data augmentation has yielded encouraging results in mathematical reasoning. However, these approaches face constraints in problem diversity, potentially restricting them to in-domain/distribution data generation. To this end, we propose **ControlMath**, an…

Alleviating Over-smoothing for Unsupervised Sentence Representation

ACL 2023long

Currently, learning better unsupervised sentence representations is the pursuit of many natural language processing communities. Lots of approaches based on pre-trained language models (PLMs) and contrastive learning have achieved promising results on this task. Experimentally, we observe that the o…

Structural Contrastive Pretraining for Cross-Lingual Comprehension

ACL 2023findings

To present, multilingual language models trained using various pre-training tasks like mask language modeling (MLM) have yielded encouraging results on a wide range of downstream tasks. Despite the promising performances, structural knowledge in cross-lingual corpus is less explored in current works…
