Matching Neural Network for Extreme Multi-Label Learning

Published in 4th International Conference on Artificial Intelligence Applications and Technologies (AIAAT 2020), 2020

We propose MNN, a neural matching framework for extreme multi-label learning that maps features and labels into aligned representations via contrastive learning, overcoming tail-label challenges.

BoostXML: Gradient Boosting for Extreme Multilabel Text Classification With Tail Labels

Published in IEEE Transactions on Neural Networks and Learning Systems, 2023

We present BoostXML, a deep learning-based extreme multilabel text classification method enhanced by gradient boosting, which specifically improves tail-label prediction through a Boosting Step that optimizes residuals from unfitted tail-label instances, a Corrective Step to avoid optimization mismatches, and a Pretraining Step to balance label focus.

LLMs as Zero-shot Graph Learners: Alignment of GNN Representations with LLM Token Embeddings

Published in 38th Conference on Neural Information Processing Systems (NeurIPS 2024), 2024

We propose TEA-GLM, a zero-shot graph learning framework that aligns GNN representations with LLM token embeddings via a fixed linear projector, enabling cross-task and cross-dataset generalization without LLM fine-tuning.

Memory-Tuning: A Unified Parameter-Efficient Tuning Method for Pre-Trained Language Models

Published in IEEE Transactions on Audio, Speech and Language Processing, 2024

We propose memory-tuning, a novel parameter-efficient method that unifies task-specific knowledge learning for both multi-head attention and feed-forward networks in Transformers, theoretically linking it to prefix tuning while outperforming full fine-tuning on eight benchmarks across sentence- and token-level tasks.

Beyond One-Size-Fits-All: Adaptive Subgraph Denoising for Zero-Shot Graph Learning with Large Language Models

Published in SIGKDD, 2026

To address the noise and suboptimality of fixed subgraph extraction in zero-shot graph reasoning, we propose GraphSSR, a framework that utilizes a “Sample-Select-Reason” (SSR) pipeline, supervised fine-tuning (SSR-SFT), and reinforcement learning (SSR-RL) to enable Large Language Models to adaptively extract and denoise task-relevant graph structures for superior generalization.

Strategy-Aware Optimization Modeling with Reasoning LLMs

Published in ICML, 2026

This paper introduces SAGE, a strategy-aware framework that makes modeling strategies explicit via solver-verified multi-strategy data and Segment-Weighted GRPO. It significantly boosts the reliability, correctness, and solver efficiency of LLMs in automated optimization modeling, outperforming strong baselines across eight benchmarks.
