How do Large Language Models Handle Multilingualism?

no code implementations29 Feb 2024 Yiran Zhao, Wenxuan Zhang, Guizhen Chen, Kenji Kawaguchi, Lidong Bing

We introduce a framework that depicts LLMs' processing of multilingual inputs: In the first several layers, LLMs understand the question, converting multilingual inputs into English to facilitate the task-solving phase.

Exploring the Potential of Large Language Models in Computational Argumentation

1 code implementation15 Nov 2023 Guizhen Chen, Liying Cheng, Luu Anh Tuan, Lidong Bing

As large language models have demonstrated strong abilities in understanding context and generating natural language, it is worthwhile to evaluate the performance of LLMs on various computational argumentation tasks.

JsonTuning: Towards Generalizable, Robust, and Controllable Instruction Tuning

1 code implementation4 Oct 2023 Chang Gao, Wenxuan Zhang, Guizhen Chen, Wai Lam

Instruction tuning has emerged as a crucial process for harnessing the capabilities of large language models (LLMs) by providing explicit task instructions, leading to improved performance in various tasks.

Domain-Expanded ASTE: Rethinking Generalization in Aspect Sentiment Triplet Extraction

no code implementations23 May 2023 Yew Ken Chia, Hui Chen, Wei Han, Guizhen Chen, Sharifah Mahani Aljunied, Soujanya Poria, Lidong Bing

Aspect Sentiment Triplet Extraction (ASTE) is a subtask of Aspect-Based Sentiment Analysis (ABSA) that considers each opinion term, their expressed sentiment, and the corresponding aspect targets.

Zero-Shot Text Classification via Self-Supervised Tuning

1 code implementation19 May 2023 Chaoqun Liu, Wenxuan Zhang, Guizhen Chen, Xiaobao Wu, Anh Tuan Luu, Chip Hong Chang, Lidong Bing

In this work, we propose a new paradigm based on self-supervised learning to solve zero-shot text classification tasks by tuning the language models with unlabeled data, called self-supervised tuning.
