Debiased Active Learning with Variational Gradient Rectifier

AAAI 2025technical

The strategy of selecting ``most informative'' hard samples in active learning has proven a boon for alleviating the challenges of few-shot learning and costly data annotation in deep learning. However, this very preference towards hard samples engenders bias issues, thereby impeding the full potent…

EffiQA: Efficient Question-Answering with Strategic Multi-Model Collaboration on Knowledge Graphs

COLING 2025main

While large language models (LLMs) have shown remarkable capabilities in natural language processing, they struggle with complex, multi-step reasoning tasks involving knowledge graphs (KGs). Existing approaches that integrate LLMs and KGs either underutilize the reasoning abilities of LLMs or suffer…

SPEA: Large-Scale Entity Alignment via Self-Partitioning

ICASSP 2025accepted

The task of entity alignment (EA) seeks to identify corresponding entities across different knowledge graphs (KGs). However, in large-scale KG alignment tasks, the complexity of the problem renders traditional entity structure representation methods, designed for small-scale KGs, ineffective. Partit…
