??? Buffala-LoRa-TH

Buffala-LoRA是一个使用7个参数的LLaMA模型，经过微调以遵循指令。它是在斯坦福大学的Alpaca（TH Translated），Wisesignt，WikiTH，Pantip和IAppQ&A数据集上进行训练的，并利用了Huggingface LLaMA实现。有关更多信息，请访问 the project's website

问题和下一步计划？

• 该模型仍然缺乏大量的世界知识，因此有必要在更大的泰国数据集上进行微调 > 下一个版本：CCNet，OSCAR，thWiki
• 目前还没有翻译提示。我们计划很快在SCB泰英数据集上对模型进行微调。
• 该模型与LangChain Search agent（Serpapi）配合使用效果良好，作为世界知识的临时解决方案 > Spaces与搜索链演示计划
• 缺乏聊天功能，等待LangChain实现。
• Colab演示。
• 用于数据集和训练笔记的Github。
