Connecting the Dots: Inferring Patent Phrase Similarity with Retrieved Phrase Graphs

Zhuoyi Peng, Yi Yang

Findings of the North American Chapter of the Association for Computational Linguistics (NAACL Findings) 2024

We study patent phrase similarity and propose a graph-augmented approach that enriches each phrase with a retrieved phrase graph, capturing the technical semantics that isolated phrases miss.

Beyond the Golden Teacher: Enhancing Graph Learning through LLM-GNN Co-teaching

Zhuoyi Peng, Hanlin Gu, Lixin Fan, Yi Yang

Preprint. arXiv preprint 2026

A co-teaching framework in which an LLM and a GNN supervise each other, moving beyond a single fixed teacher to improve graph representation learning.

Adversarial Mixup Unlearning

Zhuoyi Peng, Yixuan Tang, Yi Yang

International Conference on Learning Representations (ICLR) 2025

We regularize machine unlearning with synthesized mixup samples that simulate data most susceptible to catastrophic forgetting, achieving reliable removal without degrading retained knowledge.
