全量微调是美味的,但是若没有太多的计算资源,那么存在两种方法可以在有限的资源下将模型调教得较为服帖。一 种是X-shot Prompt,这点在介绍Dspy的时候说过了。另外一种是高效参数微调(微调部分参数),简称PEFT(Parameter-efficient fine tuning)。本系列还是会将重点放在PEFT的技术上面。2.PEFT概览 最后先来...
Fine-tuning 的主要工作原理如下: 预训练模型初始化: 与RAG 类似,微调也从初始化预训练语言模型开始,该模型之前已在大型多样化数据集上进行过训练。预训练阶段使模型具备对语言模式、语义和上下文的广义理解,这使其成为各种 NLP 任务的宝贵起点。 特定任务数据集: 预训练后,模型将在较小的特定任务数据集上进行微调...
Prefix-Tuning(P-Tuning v2)[12] Prompt Tuning [13] Lora / QLora [14] 根据实际经验,这里推荐采用 Lora 或 QLora。简单介绍一下 QLoRA,重点改进是将模型采用 4bit 量化后加载,训练时把数值反量化到 bf16 后进行训练,利用 LoRA 可以锁定原模型参数不参与训练,只训练少量 LoRA 参数的特性使得训练所需的显...
a chatbot that is used in a customer service application would need to be able to understand the customer’s intent and respond accordingly. Fine-tuning an LLM for this type of application would be difficult, as it would require a large dataset of labeled data that captures the different cont...
