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.

Where to go? Predicting next location in IoT environment

Published in Frontiers of Computer Science, 2020

We propose TSIS, a neural model that jointly learns from trajectory transitions and IoT signal sequences via gated GNNs and GRUs for accurate next-location prediction in IoT environments.

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.
