arxiv preprint – LongLoRA: Efficient Fine-tuning of Long-Context Large Language Models

In this episode, we discuss LongLoRA: Efficient Fine-tuning of Long-Context Large Language Models by Yukang Chen, Shengju Qian, Haotian Tang, Xin Lai, Zhijian Liu, Song Han, Jiaya Jia. The abstract describes “LongLoRA,” a technique designed to efficiently expand the context size of large language models (LLMs) while maintaining computational feasibility. This methodology includes a novel “shifted sparse attention” mechanism and an improved Low-Rank Adaptation process for resource-efficient fine-tuning. It has been successfully tested on various tasks, offering increased context without requiring changes to the original model architecture, and is supported by openly available resources including the LongAlpaca dataset.
