Welcome to our repository, which contains a diverse collection of Subspace Tuning methods for Parameter-Efficient Fine-Tuning (PEFT). Subspace Tuning are essential for adapting large pre-trained models to specific tasks with minimal changes to the original parameters. It endeavors to identify the maximal projection of the optimal weight
We aim to provide a comprehensive resource for researchers and practitioners in this field, and facilitate easy integration into your projects. Whether you are here to find resources for your projects or to contribute, we hope this repository will be a valuable and inspiring part of your research journey.
This repository also contains some of the other projects we have worked on, which might have led you here.

We support several tasks including:
- Natural Language Understanding (NLU)
- Natural Language Generation (NLG)
- Question Answering (QA)
- Commonsense Reasoning (CR)
- Math Reasoning (MR)
- Subject-driven Generation (SdG)
- ...
Based on subspace tuning theory, PEFT methods are classified into three categories: reconstruction-based, extension-based and combination-based.
We implement different methods mainly in loralib/.
