ChatGPT的Fine-tuning涉及到将模型暴露在各种对话和语境中,以便它能够更好地理解并生成自然对话。举个例子,如果我们想要让ChatGPT用于医疗咨询,Fine-tuning的过程将包括让模型学习医学知识、专业术语和与患者交流的最佳实践。这种Fine-tuning使得ChatGPT能够根据任务的特定上下文作出更准确的回应。 微调可让你通过 API 提...
ChatGPT作为GPT家族的一员,已经在多个领域展现了出色的表现,而其背后的Fine-tuning和Embeddings技术则是其成功的关键因素之一。 2.内容 2.1 什么是Fine-tuning Fine-tuning,又称微调,是指在预训练模型(如GPT-3)的基础上,通过在特定任务上继续训练模型,使其适应特定任务的需求。GPT-3在大规模文本语料上进行了预...

BioinformaticsMachine LearningFinetuningMOTIVATION. Proteins with unknown function are frequently compared to better characterized relatives, either using sequence similarity, or recently through similarity in a learned embedding space. Through comparison, protein sequence embeddings allow for interpretable and ...
RESULTS. We find that for functional annotation of proteins, as represented by Gene Ontology (GO) terms, direct fine-tuning of language models on a simple classification loss has an immediate positive impact on protein embedding quality. Fine-tuned embeddings show stronger performance as ...
