-因此，本课程将重点介绍**针对指令微调 LLM 的最佳实践**，我们也建议您将其用于大多数使用场景。在继续之前，我想感谢 OpenAI 和 DeepLearning.ai 团队为 Isa 和我所提供的材料作出的贡献。我非常感激 OpenAI 的 Andrew Main、Joe Palermo、Boris Power、Ted Sanders 和 Lillian Weng，他们参与了我们的头脑风暴材料的制定和审核，为这个短期课程编制了课程大纲。我也感激 Deep Learning 方面的 Geoff Ladwig、Eddy Shyu 和 Tommy Nelson 的工作。 -

"我们讨论了如何通过一系列步骤加载与用户查询相关的信息，为模型提供所需的上下文，以有效回答问题。\n", + "\n", + "您可能会想，为什么我们选择性地将产品描述加载到提示中，而不是包含所有产品描述，让模型使用它所需的信息呢？\n", + "\n", + "这其中有几个原因。\n", + "\n", + "首先，包含过多的产品描述可能会使模型在处理上下文时感到困惑，就像对于试图一次处理大量信息的人一样。当然，对于像 GPT-4 这样更高级的模型来说，这个原因就不太重要了。尤其是当上下文像这个例子一样具有良好的结构时，模型足够聪明，能够巧妙地忽略那些明显不相关的信息。\n", + "\n", + "接下来的原因更加具有说服力。\n", + "\n", + "首先，包含所有产品描述可能会使模型对上下文更加混乱，就像对于试图一次处理大量信息的人一样。当然，对于像 GPT-4 这样更高级的模型来说，这个问题不太相关，特别是当上下文像这个例子一样结构良好时，模型足够聪明，只会忽略明显不相关的信息。接下来的原因更有说服力。\n", + "\n", + "第二个原因是，语言模型有上下文限制，即固定数量的 token 允许作为输入和输出。如果您有一个巨大的产品目录，您甚至无法将所有描述都放入上下文窗口中。\n", + "\n", + "最后一个原因是，包含所有产品描述可能会使模型过拟合，因为它会记住所有的产品描述，而不是只记住与查询相关的信息。这可能会导致模型在处理新的查询时表现不佳。\n", + "\n", + "使用语言模型时，由于按 token 付费，可能会很昂贵。因此，通过有选择地加载信息，可以减少生成响应的成本。一般来说，确定何时动态加载信息到模型的上下文中，并允许模型决定何时需要更多信息，是增强这些模型能力的最佳方法之一。\n", + "\n", + "并且要再次强调，您应该将语言模型视为需要必要上下文才能得出有用结论和执行有用任务的推理代理。因此，在这种情况下，我们必须向模型提供产品信息，然后它才能根据该产品信息进行推理，为用户创建有用的答案。\n", + "\n", + "在这个例子中，我们只添加了一个特定函数或函数的调用，以通过产品名称获取产品描述或通过类别名称获取类别产品。但是，模型实际上擅长决定何时使用各种不同的工具，并可以正确地使用它们。这就是 ChatGPT 插件背后的思想。我们告诉模型它可以访问哪些工具以及它们的作用，它会在需要从特定来源获取信息或想要采取其他适当的操作时选择使用它们。在这个例子中，我们只能通过精确的产品和类别名称匹配查找信息，但还有更高级的信息检索技术。检索信息的最有效方法之一是使用自然语言处理技术，例如命名实体识别和关系提取。\n", + "\n", + "另一方法是使用文本嵌入（Embedding）来获取信息。嵌入可以用于实现对大型语料库的高效知识检索，以查找与给定查询相关的信息。使用文本嵌入的一个关键优势是它们可以实现模糊或语义搜索，这使您能够在不使用精确关键字的情况下找到相关信息。因此，在此例子中，我们不一定需要产品的确切名称，而可以使用更一般的查询如 **“手机”** 进行搜索。我们计划很快推出一门全面的课程，介绍如何在各种应用中使用嵌入，敬请关注。\n", + "\n", + "在下一章中我们将讨论如何评估语言模型的输出。" + ] + }, + { + "cell_type": "markdown", + "metadata": {}, + "source": [ + "## 附录: 英文版提示" + ] + }, + { + "cell_type":
