大语言模型

大语言模型(LLM)是指使用大量文本数据训练的深度学习模型,可以生成自然语言文本或理解语言文本的含义。大语言模型可以处理多种自然语言任务,如文本分类、问答、对话等,是通向人工智能的一条重要途径。

发展历史

2020年9月,OpenAI授权微软使用GPT-3模型,微软成为全球首个享用GPT-3能力的公司。2022年,Open AI发布ChatGPT模型用于生成自然语言文本。2023年3月15日,Open AI发布了多模态预训练大模型GPT4.0。

2023年2月,谷歌发布会公布了聊天机器人Bard,它由谷歌的大语言模型LaMDA驱动。2023年3月22日,谷歌开放Bard的公测,首先面向美国和英国地区启动,未来逐步在其它地区上线。

2023年2月7日,百度正式宣布将推出文心一言,3月16日正式上线。文心一言的底层技术基础为文心大模型,底层逻辑是通过百度智能云提供服务,吸引企业和机构客户使用API和基础设施,共同搭建AI模型、开发应用,实现产业AI普惠。

开源大语言模型

本文列举了截止到 2023 年 6 月 8 日开源的大语言模型

1、LLaMA

简介

聚宝盆(Cornucopia): 基于中文金融知识的LLaMA微调模型

本项目开源了经过中文金融知识指令精调/指令微调(Instruct-tuning) 的LLaMA-7B模型。通过中文金融公开数据 爬取的金融数据构建指令数据集,并在此基础上对LLaMA进行了指令微调,提高了 LLaMA 在金融领域的问答效果。

基于相同的数据,后期还会利用GPT3.5 API构建高质量的数据集,另在中文知识图谱-金融上进一步扩充高质量的指令数据集。

论文和代码

代码:https://github.com/jerry1993-tech/Cornucopia-LLaMA-Fin-Chinese/tree/main

数据集构建

目前采用了公开和爬取的中文金融领域问答数据,涉及到保险、理财、股票、基金、贷款、信用卡、社保等

指令微调的训练集数据示例如下:

问题:办理商业汇票应遵守哪些原则和规定?

回答: 办理商业汇票应遵守下列原则和规定:1.使用商业汇票的单位,必须是在银行开立帐户的法人;2.商业汇票在同城和异地均可使用;3.签发商业汇票必须以合法的商品交易为基础;4.经承兑的商业汇票,可向银行贴现;5.商业汇票一律记名,允许背书转让;6.商业汇票的付款期限由交易双方商定,最长不得超过6个月;7.商业汇票经承兑后,承兑人即付款人负有到期无条件交付票款的责任;8.商业汇票由银行印制和发售。

针对现有数据仍存在不准确和不完善的地方,后续我们会利用GPT3.5接口围绕中文金融知识库进一步构建与拓展问答数据,设置多种Prompt形式来充分利用知识迭代更新数据集。

9、minGPT

简介

A PyTorch re-implementation of GPT, both training and inference. minGPT tries to be small, clean, interpretable and educational, as most of the currently available GPT model implementations can a bit sprawling. GPT is not a complicated model and this implementation is appropriately about 300 lines of code (see mingpt/model.py). All that’s going on is that a sequence of indices feeds into a Transformer, and a probability distribution over the next index in the sequence comes out. The majority of the complexity is just being clever with batching (both across examples and over sequence length) for efficiency.

Vicuna Weights

We release Vicuna weights as delta weights to comply with the LLaMA model license. You can add our delta to the original LLaMA weights to obtain the Vicuna weights. Instructions:

Get the original LLaMA weights in the Hugging Face format by following the instructions here.

Use the following scripts to get Vicuna weights by applying our delta. They will automatically download delta weights from our Hugging Face account.

14、alpaca-lora

简介

This repository contains code for reproducing the Stanford Alpaca results using low-rank adaptation (LoRA). We provide an Instruct model of similar quality to text-davinci-003 that can run on a Raspberry Pi (for research), and the code is easily extended to the 13b, 30b, and 65b models

In addition to the training code, which runs within hours on a single RTX 4090, we publish a script for downloading and inference on the foundation model and LoRA, as well as the resulting LoRA weights themselves. To fine-tune cheaply and efficiently, we use Hugging Face’s PEFT as well as Tim Dettmers’ bitsandbytes.

Without hyperparameter tuning, the LoRA model produces outputs comparable to the Stanford Alpaca model. (Please see the outputs included below.) Further tuning might be able to achieve better performance; I invite interested users to give it a try and report their results.
