Llama 2 is a family of generative text models that are optimized for assistant-like chat use cases or can be adapted for a variety of natural language generation tasks. Code Llama models are fine-tuned for programming tasks. Credit: Mariem_Ekatherina / Shutterstock Llama 2 is a family of...
LLaMA(英语:Large Language Model Meta AI,直译:大语言模型元AI)是Meta AI公司于2023年2月发布的大型语言模型。它训练了各种模型,这些模型的参数从70亿到650亿不等。LLaMA的开发人员报告说,LLaMA运行的模型在大多数NLP基准测试中的性能超过了更大的、具有提供的模型,且LLaMA的模型可以与和等最先进的模型竞争。虽然...

(2)使用DPO直接偏好对齐 论文:《Direct Preference Optimization: Your Language Model is Secretly a Reward Model 》 论文地址:https://arxiv.org/abs/2305.18290 背景:RLHF是一个复杂、不稳定、难训练的过程(用reward model进行ppo强化学习等),而DPO可以避开训练奖励模型这个步骤,直接对排序数据集进行直接偏好学习。
The release of the C4_200M Synthetic Dataset and advancements in LLaMA2's QLoRA fine-tuning technology present an unprecedented opportunity to examine these issues more closely. This study aims to assess the performance of the LLaMA2 in the area of GEC. In this study, we implemented LLaMA2 ...
The UNK token already has a role in the model. Ideally, we want a pad token that is used only for padding. We have to create from scratch a pad token in the vocabulary if it doesn’t exist. This is the solution recommended by Hugging Face for Llama 2. ...
Llama 2, which was released in July 2023, has less than half the parameters than GPT-3 has and a fraction of the number GPT-4 contains, though its backers claim it can be more accurate. On the other hand, the use of large language models could drive new instances of shadow IT in ...
Llama2 achieves state-of-the-art performance compared to other generative language models, with a Rouge-1 score of 0.4834 on MIMIC-CXR and 0.4185 on OpenI. Additional assessments by radiology experts highlight the model's strengths in understandability, coherence, relevance, conciseness, and ...
项目地址:github.com/facebookresearch/llama 注意上面这个项目地址是llama的推理代码,不是训练代,里面的模型下载可以直接在百度搜一下,不用按照meta的方式下载,太慢了,这里提供一个模型下载地址https://openai.wiki/llama-model-download.html 几周前,MetaAI推出了大语言模型LLaMA,其不同版本包括70亿、130亿、330亿...
A large language model utilizes massive datasets, often featuring 100 million or more parameters, in order to solve common language problems. Developed by OpenAI, ChatGPT is one of the most recognizable large language models. Google's BERT, Meta’s Llama 2, and Anthropic's Claude 2 are other...
