Unsupervised Relation Extraction: A Variational Autoencoder Approach

no code implementations EMNLP 2021 Chenhan Yuan, Hoda Eldardiry

We propose a VAE-based unsupervised relation extraction technique that overcomes this limitation by using the classifications as an intermediate variable instead of a latent variable.

No Language is an Island: Unifying Chinese and English in Financial Large Language Models, Instruction Data, and Benchmarks

3 code implementations10 Mar 2024 Gang Hu, Ke Qin, Chenhan Yuan, Min Peng, Alejandro Lopez-Lira, Benyou Wang, Sophia Ananiadou, Wanlong Yu, Jimin Huang, Qianqian Xie

While the progression of Large Language Models (LLMs) has notably propelled financial analysis, their application has largely been confined to singular language realms, leaving untapped the potential of bilingual Chinese-English capacity.

Dólares or Dollars? Unraveling the Bilingual Prowess of Financial LLMs Between Spanish and English

2 code implementations12 Feb 2024 Xiao Zhang, Ruoyu Xiang, Chenhan Yuan, Duanyu Feng, Weiguang Han, Alejandro Lopez-Lira, Xiao-Yang Liu, Sophia Ananiadou, Min Peng, Jimin Huang, Qianqian Xie

We evaluate our model and existing LLMs using FLARE-ES, the first comprehensive bilingual evaluation benchmark with 21 datasets covering 9 tasks.

GradXKG: A Universal Explain-per-use Temporal Knowledge Graph Explainer

no code implementations7 Oct 2023 Chenhan Yuan, Hoda Eldardiry

This helps address the lack of interpretability in existing TKGR models and provides a universal explanation approach applicable across various models.

Back to the Future: Towards Explainable Temporal Reasoning with Large Language Models

1 code implementation2 Oct 2023 Chenhan Yuan, Qianqian Xie, Jimin Huang, Sophia Ananiadou

In this paper, we introduce the first task of explainable temporal reasoning, to predict an event's occurrence at a future timestamp based on context which requires multiple reasoning over multiple events, and subsequently provide a clear explanation for their prediction.

Clustering-based Unsupervised Generative Relation Extraction

no code implementations26 Sep 2020 Chenhan Yuan, Ryan Rossi, Andrew Katz, Hoda Eldardiry

To address this issue, we propose a Clustering-based Unsupervised generative Relation Extraction (CURE) framework that leverages an "Encoder-Decoder" architecture to perform self-supervised learning so the encoder can extract relation information.

Reinforcement Learning-based N-ary Cross-Sentence Relation Extraction

no code implementations26 Sep 2020 Chenhan Yuan, Ryan Rossi, Andrew Katz, Hoda Eldardiry

In this paper, we relax this strong assumption by a weaker distant supervision assumption to address the second issue and propose a novel sentence distribution estimator model to address the first problem.

Efficient text generation of user-defined topic using generative adversarial networks

no code implementations CCNLG (ACL) 2019 Chenhan Yuan, Yi-chin Huang, Cheng-Hung Tsai

The objective results showed that the proposed method is capable of generating texts with less time than others and the generated text is related to the user-defined topic and sentiment.
