在最开始我用了很多方法进行训练,但其他的方法我都用了很长的时间训练,在显卡不足的情况下,根本不适合穷人进行fune-tuning得到丐版的Llama2。最后我发现axolotl这玩意儿还有点意思,用这个工具可以轻松对大模型进行微调。关键问题是,你用axolotl进行微调,只需要对我们的大模型meta-llama/Llama-2-7b-hf指定一个yaml文...
括号中的数字表示相对于未经过任何微调的 LLaMA-7B 基础模型的性能提升。 在这两种情况下,LoRA-FA 几乎将可训练参数的数量减少了一半。 3️⃣ VeRA 介绍 VeRA(Vector-based Random Matrix Adaptation,基于向量的随机矩阵适应)技术可以进一步减少 LoRA 中可训练参数数量,同时能够匹配或接近 LoRA 的精度。 如前所...
Finetuning Llama-2-7BGanesh Saravanan 0 Reputation points Sep 7, 2023, 7:41 PM Hi, I needed to know if it is possible to finetune Llama-2 7B model, through azure model catalog. And the finetune (for llama-2-chat) mentions text classification, but i want to finetune for a different...
LongLoRA 通过使用一种简化的注意力形式和 LoRA 方法来高效扩展上下文长度,成功在 LLaMA2 7B/13B/70B 模型上将上下文长度扩展至 32K、64K、100K,几乎不增加算力消耗。此外,研究还创建了 LongQA 数据集来进一步改进模型的输出能力,并证明了通过增加训练信息量可以获得更好的结果。LongLoRA 不仅兼容现有技术,而且在处理...
Neural Magic 致力于在标准 CPU 基础设施上高效部署深度学习模型,如 Llama 2。通过结合剪枝、量化与 DeepSparse,展示了在 CPU 上加速 Llama 2 推理而不影响准确性。今天,我们宣布 DeepSparse 支持 Llama 2,并扩展了 Sparse Fine-Tuning 研究至 Llama 2 7B。研究证明了软件加速方法在领先模型架构上...
2、Instruction Tuning LLaMA Stanford alpaca对LLaMA采用Instruction Tuning的方式对LLaMA进行finetune,让其适配下游任务。Instruction Tuning的核心是将各类NLP任务转换成自然语言的形式,构造任务的Instruction-output对,将其输入大模型中finetune大模型参数。 具体的样本构造上,首先生成175个基础的Instruction-output对,然后将...
In this research paper, we explore the optimization for conversation summarization of the Llama 2.7 b model by quantization-aware fine-tuning, specifically exploiting QLORA quantization techniques. In natural language processing (NLP), large language models (LLMs) have become powerful tools for various...
