Biography

Hi! I’m a third-year PhD student in computer science at The University of Hong Kong, advised by Lingpeng Kong and BCM Kao. I have previously interned at Tencent AI Lab, working with Piji Li and Wei Bi.

My primary research interests lie in the area of natural language processing and machine learning. My research aims to build robust and explainable AI systems that can understand natural language text and solve real-world problems, concerning both performance and social implications. Toward this goal, my work spans LLM alignment, long-range planning, and applications in mathematical reasoning.

Interests

  • LLM alignment
  • Long-range planning
  • Mathematical reasoning

Education

  • M.Sc. in Computer Science, 2021

Collaborative Evaluation: Exploring the Synergy of Large Language Models and Humans for Open-ended Generation Evaluation

To explore the synergy between humans and LLM-based evaluators and address the challenges of existing inconsistent evaluation criteria in open-ended NLG tasks, we propose a Collaborative Evaluation pipeline CoEval.

Retrieved Sequence Augmentation for Protein Representation Learning

We introduce Retrieved Sequence Augmentation(RSA) for protein representation learning without additional alignment or pre-processing. RSA links query protein sequences to a set of sequences with similar structures or properties in the database and combines these sequences for downstream prediction. (EMNLP 2024)

GSM-Plus: A Comprehensive Benchmark for Evaluating the Robustness of LLMs as Mathematical Problem Solvers

We introduce the adversarial grade school math (GSM-Plus) dataset, an extension of GSM8K augmented with various mathematical perturbations. Our experiments on 25 LLMs and 4 prompting techniques show that while LLMs exhibit different levels of math reasoning abilities, their performances are far from robust. (ACL 2024)

MAGE: Machine-generated Text Detection in the Wild

Recent advances in large language models highlights the importance of deepfake text detection to avoid potential risks such as fake news propagation and plagiarism. We build a wild testbed by gathering texts from various human writings and deepfake texts generated by different LLMs. (ACL 2024)

BBA: Bi-Modal Behavioral Alignment for Reasoning with Large Vision-Language Models

We introduce the Bi-Modal Behavioral Alignment prompting method, designed to maximize the potential of Domain-Specific Languages (DSL) in augmenting complex multi-modal reasoning tasks. BBA initiates by guiding large vision-language models to create separate reasoning chains for visual and DSL representations. (Findings of ACL 2024)

Explanation Regeneration via Information Bottleneck

Explanations generated through single-pass prompting often lack sufficiency and conciseness, we develop an information bottleneck method to produce refined explanations that are sufficient and concise. (Findings of ACL 2023)

A Cognitive Stimulation Dialogue System with Multi-source Knowledge Fusion for Elders with Cognitive Impairment

When communicating with elders with cognitive impairment, cognitive stimulation (CS) helps to maintain the cognitive health of elders. We construct a Chinese CS conversation dataset and propose a multi-source knowledge fusion method for CS dialogue. (ACL 2023)

Efficient Zero-shot Learning via Dataset Generation

We study a flexible and efficient zero-short learning method. Given a zero-shot task, we first generate a dataset from scratch using PLMs in an unsupervised manner. Then, we train a tiny task model under the supervision of the synthesized dataset. (EMNLP 2022)

Abstractive Opinion Tagging

We propose a new task, abstractive opinion tagging, and a dataset, eComTag, to generate opinion tags based on large volumes of item reviews. (WSDM 2021, oral paper)

Empathetic Dialogue Generation

A humanized dialogue system is expected to generate empathetic replies, which should be sensitive to the users’ expressed emotion. The task of empathetic dialogue generation is proposed to address this problem.

Text Summarization

Given single-documents or multi-documents, summarizing the opinions expressed of the input is a vital task in NLP. I divide the current researches into two categories: keyphrase generation and opinion summarization.
