Invited Talk: How Do Large Language Models Capture the Ever-changing World Knowledge? A Review of Recent Advances

Speaker: Prof. Ling Chen |  School of Computer Science, University of Technology Sydney

Abstract: 

Large language models (LLMs) have shown impressive performance in solving various tasks. However, as the world is constantly changing and new information is being generated every day, the trained LLM can be quickly outdated without re-training, which can be a time-consuming and resource-intensive process. Consequently, maintaining LLMs up-to-date status is a pressing concern in the current era. In this talk, I will provide a review of recent advances in aligning LLMs with the ever-changing world knowledge without re-training from scratch, by categorizing research works and providing in-depth comparisons and discussion. I will also discuss existing challenges and highlight future directions to facilitate research in this field.
