当前大多数基于 AI 的工具都是生成式的——它们生成文本和图像,使用生成式预训练模型(GPTs)来完成这些任务。而对于需要处理现有文本的用例——例如文本分类或意图识别——sentence transformers 是首选工具。在这个领域,SetFit是一个用于微调 sentence transformers 的框架。我们喜欢 SetFit 的原因是它使用对比学习来区分不同的意图类别,通常只需非常少量的样本(甚至少于 25 个)就能实现清晰的分类。sentence transformers 在生成式 AI 系统中也可以发挥作用。我们成功地在一个使用大语言模型(LLM)的客户聊天机器人系统中使用 SetFit 进行意图检测。尽管我们知晓 OpenAI 的内容审核 API,我们仍选择基于 SetFit 的分类器进行额外的微调,以实现更严格的过滤。
