Sit Down Plz

哈喽，大家好，欢迎收听今天的节目。最近的一段时间，大家应该能够发现，GBT对于我的影响还是非常巨大的。呃，无论是在我的工作还是在生活中，我都在尝试它，看看它能够给我带来哪些以前很难获得的东西。但也正是因为如此呢，才使得我能够更加深刻的理解去了解它的一些优势。当然，也帮助我去更加清楚地去知道它的哪些不足。所以我在想，今天我们是不是可以用一期节目好好的聊一聊AI，以及目前它的代表作ChatGPT到底能够给我们的生活和工作带来哪些层面的变化？

本期内容我们会涉及到：

1. ChatGPT不是一个聊天工具

2. AI的自我保护以及我们为什么需要Prompt engineering

3. ChatGPT不是万能的，但貌似也是万能的

4. 到底什么才是真实的，事实还在你的手上吗？

5. 都说最不值钱的是想法？可是现在呢？

6. 对于开发而言，他真的能够提升十倍的效率吗？

7. 互联网产品会发生哪些改变？入口的争夺

Hello 大家好，欢迎收听我们今天的节目。相信这几天关心GPT发展的朋友们大多都发现了这样的一个事情，那就是GPT以及其他的AGI服务开始封杀用户了。最开始是Midjourney封杀了大量的免费用户，因为他们发现很多的用户在免费额度用完之后就开始批量注册新的免费用户，这样给Midjourney的服务带来了巨大的压力，因此Midjourney一不做二不休直接停止了免费用户的使用，同时还封禁了一批批量注册的账号。而就在Midjourney的风波还没过去的期间，我们又发现了Openai开始封锁不合规使用他们服务的账号了。而且不论这个账号是否开通了chatgpt plus，一时间各种猜测，各种阴谋论蜂拥而至，不过仔细一想，这些都是很正常的事情，因为这些AGI服务都是商业化的，他们的目的就是为了赚钱，而不是为了给我们免费提供服务。况且现在还有安全合规的风险，非法的不合规的使用肯定会带来一些不可预知的风险，所以一不做二不休，直接封杀。不过，我觉得openai封杀账号的背后肯定还有别的原因，我不是什么阴谋论者，也不知道任何的内幕，但是从一些事情变化的迹象上看，还是能够窥探出一些信息的。

我们都知道，openai在3月14日公布了他们的GPT4模型，并且直接就开发了服务，Chatgpt plus的用户可以直接的使用GPT4模型用于他们的对话，这一点是值得称赞的。但是GPT4的服务性能直到今天都还没能够得到明显的提升。甚至还有劣化的情况，毕竟一开始GPT4的使用限制是每小时100个对话，然后逐渐降到了印象中是每2小时50个对话，最近则又降到了每3小时25个对话。其实我认为这才是openai目前封禁用户不合规使用的主要原因，据我看到的消息生成，每一个用户使用chatgpt完成一次对话，平均openai会独占2两块A100显卡5秒钟。而考虑到GPT4模型的规模要大很多，资源的使用势必也会翻倍，这样也就不难解释为什么GPT4的服务质量一直很难得到提升的原因了，因为目前GPT4的使用量显然还处于上升期，而这个阶段资源消耗的增量显然是高于优化速度的，这从前面的使用量限制就不难看出来，那么在这种情况下，作为openai最明星的产品，如何能够保障，就别说提升了，GPT4的服务呢，最为简单有效的方式就是更加合理的分配chatgpt对于资源的消耗了，而为了实现这个，最简单的方法当然就是停止或者限制非法使用的情况。这也就不难解释为什么openai会在现在动手了。

好了，扯了很多有的没的。回到今天的主题，那就是我其实日常的生活和工作中已经很难离开GPT的服务了。刚好因为工作的原因，本周末我要参加TOEFL的家考，所以为了能够更好的临时抱佛脚，我自然要看看如何使用GPT来帮我备考了。所以我自然就让GPT这位语言大拿给我出出主意了。虽然日常工作中会经常的使用到英语，大家也应该知道我日常也会可以加强英语的体力，但是对于写作，确实很少染指，所以我就首先问了GPT关于写作的问题。一同寒暄之后，GPT终于给出了一些我觉得可能有用的信息，例如在TOEFL考试中高概率会被用到的词汇啊，还有一些写作的框架啊，那既然如此，为啥不让GPT直接给我做一个范文呢？所以就有了下面的这篇文章，当然我为了强化那些重点单词的记忆，强行的让GPT劣化了文章的质量，目的就是为了把这些单词给塞进去，那我们就一起看看GPT到底给出了啥吧。

首先是重点的单词，GPT整理了20多个重点的词汇，我依然按照自己喜欢的方式让GPT解释了这些词汇，并且给出了例句。

最后是GPT劣化后的范文。

The decision of where to raise children has significant implications for their development and well-being. While some people advocate for the opportunities and advantages provided by big cities, others argue that small towns and rural areas offer a more nurturing environment for children. This essay will analyze and evaluate the advantages of each perspective, synthesizing the various notions and theoretical concepts, and ultimately determining the ideal environment for children.

Big cities offer a diverse range of experiences for children, enabling them to comprehend the complexities of modern life. These urban environments often boast well-funded schools, which facilitate access to the latest technology and innovative teaching methods. Empirical evidence substantiates the claim that city schools may be more effective in preparing students for their futures. For instance, research conducted by the National Center for Education Statistics found a positive correlation between urbanicity and academic achievement in the United States. Furthermore, cities offer a wide array of extracurricular activities, fostering the development of children's interests and talents.

However, the fast-paced lifestyle in big cities can be detrimental to children's well-being. Constant exposure to noise, pollution, and stress may undermine their physical and mental health. Additionally, the prevalence of crime and safety concerns can contradict the nurturing environment essential for children's growth. Parents must carefully evaluate the potential hazards associated with urban living, weighing the benefits against the potential drawbacks.

Despite the theoretical advantages of city living, small towns and rural areas offer a more peaceful and coherent environment for children. The strong sense of community in these areas can help develop children's social skills and emotional intelligence. The slower pace of life allows children to spend more time outdoors, engaging with nature, and participating in physical activities. This hands-on experience can lead to a deeper comprehension of the world around them, fostering a sense of curiosity and wonder.

One primary advantage of small-town life is the close-knit community that often exists in these environments. Children growing up in small towns have the opportunity to form strong bonds with their neighbors, teachers, and peers, leading to a sense of belonging and security. This supportive network can be particularly beneficial during challenging times, providing a safety net for families in need.

Nonetheless, small towns and rural areas often lack the resources available in big cities. Educational facilities in these regions might not have the necessary funding and infrastructure to provide the same quality of education as their urban counterparts. Moreover, the scarcity of cultural institutions and events can restrict children's exposure to diverse perspectives and experiences.

In the quest to determine the ideal environment for children, it is important to consider the relevance of each factor in their development. While access to quality education and diverse experiences is crucial, so too is the need for a supportive and nurturing community. Parents must weigh the potential benefits and drawbacks of each environment, bearing in mind their unique circumstances and priorities.

To make an informed decision, parents can cite examples from their own experiences, as well as the experiences of others. This process may involve examining case studies, interviewing families who have raised children in various environments, and even simulating potential scenarios. By gathering a wide range of perspectives and evidence, parents can better understand the implications of their choices and make a decision that aligns with their values and objectives.

In conclusion, both big cities and small towns offer advantages and disadvantages for raising children. Cities provide a wealth of resources and opportunities, while small towns offer a more supportive and tranquil environment. The ideal setting for children is one that balances the benefits of both worlds, perhaps a small city or suburban area, where children can access resources and opportunities while still enjoying the support and serenity of a close-knit community. Parents must carefully scrutinize the various factors at play and determine the best course of action based on their individual circumstances and goals. Ultimately, the well-being and success of children depend on the choices made by their caregivers, who must carefully consider the implications of each environment and make informed decisions that best suit their children's needs.

To ensure that children can thrive in their chosen environment, parents must be aware of the ambiguities and discrepancies that may arise in each setting. This awareness can help them navigate the complexities and challenges of raising children in different environments. A proactive approach to addressing potential issues, such as ensuring access to quality education, fostering connections within the community, and promoting a healthy balance between work and leisure, can significantly impact children's development and happiness.

Ultimately, the choice between raising children in a big city or a small town depends on the specific objectives and values of each family. By considering the various factors involved, parents can make informed decisions that promote their children's well-being and personal growth. In the end, the most important factor is the love, care, and attention provided by parents and caregivers, as this will have the most profound and lasting impact on a child's life, regardless of the environment in which they grow up.

以上就是我们今天这期播客的内容，感谢大家的收听，我们下期节目再见。

友情提示：本期内容比较硬核，超长，主要目的也是为了自己整理对于GPT的理解，希望对大家也有帮助。

Hello，大家好，欢迎收听我们的播客！很高兴地告诉大家，这已经是近一周内我更新的第三期播客了！之所以能如此高效地制作播客，当然要归功于GPT模型。它在很大程度上简化了我们制作播客内容、进行知识储备、消化和整理的过程。今天，我们要谈论的内容主要是关于个人知识库整理的一些想法，这些想法源于我和ChatGPT在对话过程中的探讨。正好，身边的一些朋友也在问我关于GPT使用的技术细节，特别是如何然GPT能够基于给定的上下来进行问题的理解，例如我们需要GPT针对于一个特定的pdf文档来进行理解让后尝试回到我提出来的问题等等。于是，我就和ChatGPT进行了一番深入的沟通，一起来看看它是如何帮助我们解答这些问题的。所以，大家不要惊讶，接下来我们要谈论的内容都是在我的引导下，由GPT完整生成的。当然，这段开场白也是如此。

在这个瞬息万变的社会中，知识的积累和管理越来越受到重视。为了随时随地找到和学习相关信息，拥有个人知识库变得至关重要。传统上，我们通过整理书籍、笔记和文件来搭建知识库，但这需要我们投入大量时间和精力进行分类、归档和查找。而现在，随着技术的进步，我们有了更高效的方法来解决这个问题。

近年来，Notion这样的数字化笔记应用受到了很多人的喜爱。它提供了一个统一的平台，让我们可以轻松地创建、组织和共享各种类型的内容。通过使用Notion，我们可以构建一个简单而易于维护的知识库。然而，Notion的功能主要还是集中在对文本内容的组织和管理，对于知识的自动提取和推荐方面并没有过多涉及。

而GPT（生成预训练变压器）等自然语言处理（NLP）技术为我们提供了一种更加智能化的方式来构建、维护和扩展知识库。借助这些技术，我们可以迅速将文本资料转换成数字化格式，方便进行检索、分类和分析。更重要的是，GPT等NLP技术可以帮助我们自动提取文本中的知识点，并根据我们的需求智能地推荐新的知识内容。

因此，与Notion等传统数字化笔记应用相比，使用GPT等NLP技术构建知识库具有更强的智能性和灵活性。这种方法为我们的知识积累和管理带来了前所未有的便利，让我们能够更好地利用知识，丰富我们的生活。

所以下面我们就来一期了解下，如果我们想要使用GPT的技术来实现个人知识库的话，我们需要做些什么呢？不过在了解具体的实现方法之前，我们先来了解一下GPT的基本原理。这里就涉及到了两个非常关键的技术名词，Transformer和Embedding。这两个名词在GPT的技术实现中起到了非常重要的作用，所以我们先来了解一下这两个名词的含义。

我们都知道，计算机只能处理数字，而不能直接处理文字。因此，我们需要将文字转换成计算机可以处理的数字格式，这就是文本嵌入（embedding）的作用。文本嵌入是一种将文本表示成数值格式的技术。简单来说，文本嵌入就是将一段文字或词汇转换成计算机可以处理的数字形式。这样做的目的是让计算机更容易地理解和处理这些文本数据。举个例子，如果我们有一个句子：“我喜欢吃苹果。”，我们可以使用文本嵌入技术将这个句子转换成一串数字，以便计算机能够处理这个句子。

数值向量是一个包含一组数字的列表，通常用来表示某个对象的特征。在文本嵌入的上下文中，数值向量通常用来表示一个词或短语的特征。比如说，我们可以将“苹果”这个词表示为一个数值向量：[0.5, 0.8, -0.3]，这个向量可能表示了这个词在某个特定空间中的位置。这样一来，我们就可以通过比较不同词的数值向量来衡量它们之间的相似度。这种方法使得我们可以在计算机中更有效地处理和分析文本数据。

用更为通俗的语言来解释就是，当然也许不是那么的严谨，在文本向量化（embedding）的过程中，我们将句子中的 词语转换成数值向量（空间坐标），这些向量通常位于高维空间中。这样一来，相似的词语或句子在空间中的距离会更近，而不相似的词语或句子距离会远一些。

换句话说，向量化后的文本可以通过计算向量之间的距离（如余弦相似度）来衡量其相似度或相关性。距离较近的文本在语义上更相似，因此我们可以认为它们具有较高的相关性。这种表示方法使得我们能够更有效地进行文本比较、分类和聚类等任务。所以你理解了第一个重要的概念embedding（文本嵌入）。

所以我们可以将文本嵌入（embedding）理解为将文本转换成计算机可以处理的数字格式的过程。而Transformer则是一种用于文本嵌入的算法。它是一种基于注意力机制（Attention Mechanism）的神经网络架构，可以将文本转换成数值向量。Transformer的结构我也找了一张图(the-annotated-transformer_14_0.png (380×560) (harvard.edu))，放到了文稿中，大家可以在文稿中查看。不过相信这样，到底什么是Transformer，大家应该还是不太容易理解的，所以我也尝试用更为通俗的语言来解释一下Transformer。

Transformer 模型通过注意力机制实现对与当前任务相关的重要部分的信息的关注。注意力机制的关键思想是为文本中的每个词分配一个权重，这个权重表示当前词对于整个句子或文本的重要性。在处理文本时，模型会根据这些权重来关注那些重要的词汇，而忽略掉不太重要的信息。

为了实现这一点，Transformer 模型采用了一种称为自注意力（self-attention）的技术。自注意力机制允许模型计算每个词与其他所有词之间的关系，从而确定哪些词对于理解整个文本最为关键。具体来说，自注意力机制会为每个词生成一个查询（query）、键（key）和值（value）的向量表示。接下来，模型会计算每个词的查询向量与其他所有词的键向量之间的相似度。这个相似度值就是注意力权重。

这些权重然后与对应的值向量相乘，最后将结果相加，得到一个新的表示当前词的向量。这个新向量捕捉到了与当前词最为相关的信息，从而使模型能够关注与当前任务相关的重要部分。

通过自注意力机制，Transformer 模型可以在处理文本时灵活地关注到重要的信息，从而提高对文本的理解和表示能力。

这样说你是不是还是不太理解Transformer，有点似懂非懂的意思。没关系，我再举个例子，你看看下面这个例子，你是不是就能理解Transformer了。

想象你正在参加一个聚会，你的目标是了解关于某个特定话题（比如电影）的讨论。在房间里，有很多人在同时谈话，每个人都在说一些不同的话题。这时，你需要一种方法来判断每个人的谈话内容是否与你关心的话题相关，以及它们之间的关联程度。

为了实现这个目标，你可以尝试以下策略：

你首先会倾听每个人的谈话，找出提到了电影的那些讨论。

对于那些提到了电影的讨论，你会进一步关注这些谈话内容中的细节，了解它们与电影话题的关联程度以及其他人对这个话题的看法。

基于这些信息，你会给每个讨论分配一个权重，表示它们与你关心的话题的相关程度。

最后，你会聚焦于那些权重较高的讨论，因为它们与你关心的话题更为相关。

Transformer 模型通过自注意力机制实现了类似的过程。在处理文本时，模型首先计算每个词与其他所有词之间的关系，然后为每个词分配一个权重。这些权重表示每个词与当前任务的关联程度。通过关注这些权重较高的词，模型可以集中处理与当前任务相关的重要信息。

在这个过程中，自注意力机制可以让模型更加高效地处理文本，因为它能够同时关注多个词汇，而不需要逐个处理。这就像你可以快速地关注到聚会中与电影相关的讨论，而不必逐个倾听每个人的谈话。

总之，Transformer 模型通过自注意力机制实现了对与当前任务相关的重要信息的关注。这种机制可以让模型同时关注多个词汇，并根据它们之间的关系来判断哪些词更加重要。这样，模型就可以更好地理解文本内容，从而提高其处理能力。

好了，到这里，这集播客中最重要的技术解释就完成了，理解了这两个关键的技术，你就可以更好地理解GPT模型了。你也可以很自豪的告诉别人，你对于GPT的理解已经超过了大多数的人了。当然更为重要的是基于这两个概念的理解，你就很容易在未来的工作乃至生活中更好的思考GPT如何更好的服务于你了。

OK，那让我们来看看如何思考使用GPT来解决你的问题吧。例如今天我们要讨论的个人知识库的构建。在本集播客的开始。我们已经提到了，对于个人知识库的构建，其实目前已经有一些比较成熟的应用了，例如Notion。它提供了一个统一的平台，让我们可以轻松地创建、组织和共享各种类型的内容。通过使用Notion，我们可以构建一个简单而易于维护的知识库。那GPT的加入会带来哪些明显的变化呢？首先就是文本嵌入技术的使用，也就是知识库的构建从传统的文本形式，转换成了embedding的模式。

1. 知识库的构建：文本嵌入（Embedding）

使用embedding的模式会带来很多显而易见的好处：

    a. 降低了知识库的维护成本。因为我们不需要再去关注文本的格式，只需要关注文本的内容即可。

    b. 知识的储备更容易被计算机理解。因为我们已经将文本转换为了数值向量，计算机可以很容易地对这些向量进行处理。特别是在进行下面的这些任务的时候，使用embedding之后能够带来更加明显的效果。

        文本分类：将文本分配到一个或多个类别中。例如，情感分析、主题分类等。通过将文本转换为嵌入向量，可以让模型捕捉到文本的语义信息，从而进行分类。

        序列标注：为输入序列中的每个元素（如单词或字）分配一个标签。比如在命名实体识别任务中，我们要找出句子里的人名、地名等，就需要给每个单词贴上“人名”、“地名”等标签；在词性标注任务中，我们要标注每个单词的词性，如名词、动词等。而嵌入在这里的作用就是帮助模型更好地理解单词和它周围的上下文，以及单词之间的关系。通过将文本转换为数值向量，我们可以让计算机更容易地处理和分析这些信息。这样一来，模型就能更准确地为每个单词分配合适的标签了。

        语义相似度：衡量两个文本或对象在语义上的相似程度。嵌入向量可以捕捉对象之间的关系和相似性，因此可以用来计算语义相似度。例如，文本匹配、文本重复检测等任务。

        文本生成：根据给定的上下文生成新的文本。例如，机器翻译、文本摘要等。嵌入向量可以帮助模型理解上下文信息，从而生成符合语义的文本。

        推荐系统：根据用户的历史行为和偏好推荐相关内容。嵌入向量可以表示用户和物品之间的关系，从而实现个性化推荐。例如，协同过滤、内容推荐等。

        聚类分析：将具有相似特征的对象分组在一起。嵌入向量可以捕捉对象之间的关系和相似性，因此可以用来进行聚类分析。例如，文本聚类、图像聚类等。这里多说一点，聚类分析和文本分类有一定的联系，但它们不完全是同一个概念。它们都是将数据分组的方法，但侧重点和过程有所不同。聚类分析是一种无监督学习方法，它试图将具有相似特征的对象自动分组在一起。在聚类过程中，我们并不知道每个对象应该属于哪个类别，而是通过计算对象之间的相似性来自动进行分组。文本聚类就是将相似的文本分到一起，形成一组“主题相近”的文本集合。

        而文本分类是一种监督学习方法，它需要预先定义好类别标签，然后通过训练数据学习如何将文本正确地分配到这些预定义的类别中。在训练过程中，我们知道每个文本的正确类别标签，通过这些标签来引导模型进行分类。

        总结一下，聚类分析和文本分类都是将数据分组的方法，但聚类是无监督学习方法，侧重于发现数据内在的结构和关系；文本分类是监督学习方法，侧重于根据预先定义好的类别将数据进行分类。

        信息检索：根据查询条件从大量文档中检索相关信息。嵌入向量可以用来表示查询条件和文档之间的相似性，从而提高检索效果。例如，搜索引擎、问答系统等。

所以非常明显使用embedding之后，我们的知识库从能力上已经摆脱了文本的束缚，可以更好地帮助我们完成各种任务。但是，我们还需要解决一个问题：如何正确的使用我们的知识库？这就延展到了我们要讨论的第二个点，语义搜索（semantic search）

2. 知识库的维护：语义搜索（Semantic Search）

传统意义的搜索，对于大家来说应该并不陌生。我们可以通过关键词来查找相应的内容。不过在使用了文本embedding之后，我们可以使用语义搜索来查找知识库中的内容。语义搜索是一种基于文本内容相似性的搜索技术。我们可以使用已经生成的嵌入向量来执行语义搜索。在这个过程中，我们首先对查询问题进行嵌入处理，然后计算查询问题嵌入向量与知识库中文档嵌入向量之间的相似度，最后返回与查询问题最相关的文档。这样搜素的结果就不再是关键词匹配的结果，而是与查询问题语义上最相关的文档。这样一来，我们就可以更准确地找到我们想要的内容了。我举个例子，例如我们有一个关于动物名称的列表，然后我们可以使用语义搜索来查找这个列表中与“狗”最相关的内容。这里的“狗”可以是动物名称，也可以是动物的别称，或者是动物的描述。只要这个词与动物相关，我们就可以通过语义搜索找到与它最相关的内容。例如我们可以说，哪种动物的叫声是“汪汪”。

3. 知识库的更新：自动分类与标签

在知识库的维护过程中，我们可能需要更新现有文档的分类和标签。我们可以通过训练一个基于文本嵌入的分类模型来实现自动分类和标签功能。这个过程不需要借助GPT模型，因为我们已经通过嵌入处理将文本转换为数值向量，可以直接进行分类任务。在前面的介绍中，其实我们已经提到了，经过embedding的处理之后，数值向量的内容是可以自动的形成一定程度聚合的，虽然系统并不知道这些向量的具体含义，但是它可以通过计算向量之间的相似度来判断这些向量是否属于同一类。因此，如果我们之前已经对于内容有了一定的分类，则新增内容的分类就会显得非常容易。我们只需要将新增内容的嵌入向量与已有的分类向量进行比较，然后将新增内容分配到与其最相似的分类中即可。这样一来，我们就可以自动地将新增内容进行分类了。不过，这样做显然不是最优雅的。那有什么更为先进的方案呢？答案是肯定的，我们可以使用GPT模型来生成分类标签。我们可以将分类标签看作是一个提示，然后使用GPT模型根据提示生成分类标签。这样一来，我们就可以自动地将新增内容进行分类了。

4. 知识库的扩展：使用GPT模型生成新知识

正如前面所提到的，现有的知识库工具主要关注知识的管理。但当知识库中不存在与查询问题高度相关的内容时，我们可以利用GPT模型生成新的知识。为了实现这个目的，我们需要将查询问题转换为一个便于GPT生成知识的提示。然后，我们可以使用GPT模型根据提示生成与问题相关的新知识。

例如，假设我们正在寻找关于太阳能电池板的信息，但我们的知识库中没有太多相关内容。这时，我们可以将查询问题转换为一个GPT友好的提示，如：“请详细介绍太阳能电池板的原理、优缺点以及应用领域。”通过这样的提示，GPT模型可以生成一篇关于太阳能电池板的详细介绍，从而为我们的知识库增加新知识。

再举一个例子，假设我们想了解如何使用Python编程语言处理大量数据。但是在我们的知识库中，没有关于这个主题的详细教程。我们可以将问题转换为一个提示，如：“请给出一个使用Python处理大量数据的简单教程，包括所需库、代码示例和注意事项。”GPT模型可以根据这个提示生成一篇简单的Python教程，帮助我们了解如何处理大量数据。

通过这种方式，我们可以不断地扩展知识库，让其更加丰富和全面。需要注意的是，在某些情况下，GPT生成的知识可能不够准确或者不完整。在将生成的内容纳入知识库之前，我们需要对其进行审核和修改，确保知识库中的信息是可靠和高质量的。

5. 模型的优化：Fine-tuning

为了获得更好的查询结果和体验，我们可以考虑对GPT模型进行Fine-tuning。Fine-tuning可以让模型更好地适应特定领域的任务和数据，从而提高模型在特定任务上的性能。在Fine-tuning过程中，我们需要收集与目标领域相关的数据，并用这些数据对模型进行训练。关于fine tune我们今天就先不去展开了，后面我会用一期播客来专门的说明，当然也是因为确实找到了一些合适的听力内容。

不过，我们还是简单讨论下如何确定是否需要对 GPT 模型进行特定领域的 fine-tune。我们知道 GPT 模型已经具备了很高的理解能力，但在某些情况下，fine-tune 并不一定能带来更好的效果。因此，在决定是否进行 fine-tune 之前，我们需要仔细评估。

首先，我们需要分析我们的目标领域。如果这个领域的知识与 GPT 模型的训练数据集有很大差距，那么进行 fine-tune 可能会带来更好的效果。此外，我们还需要考虑我们的任务类型和需求。对于一些特定的任务，例如情感分析或实体识别，fine-tune 可能会提高模型性能。

其次，我们可以通过在一些样本数据上测试 GPT 模型的性能来判断是否需要 fine-tune。如果 GPT 模型在这些样本数据上表现良好，那么我们可能不需要进行 fine-tune。反之，如果模型在这些样本上的性能不佳，我们就可以考虑进行 fine-tune 以提高模型在该特定领域的表现。

6. 总结

在本期播客中，我们系统地介绍了如何通过 GPT 相关模型构建个人知识库，以及维护、更新和扩展知识库的内容。我们讨论了文本嵌入、数值向量、GPT 模型的基本概念，并解释了如何将这些技术应用于个人知识库的构建和维护。

我们还讨论了如何使用 semantic search 在知识库中查找相关信息，以及如何通过 fine-tune GPT 模型以提高在特定领域的表现。最后，我们探讨了如何确定是否需要对 GPT 模型进行 fine-tune，以及如何在实际应用中做出决策。所以与其说我们是在讨论如何构建一个智能的知识库，其实更多的还是系统化的介绍了GPT的相关技术，以及如何将这些技术应用于实际的应用场景中。希望大家喜欢本期的内容，我也希望大家能够通过我的分享真正的了解到GPT模型以及相关的ChatGPT到是什么，好了，今天我们的内容就到这里，下期节目我们再见，可能会很快。

hello，大家好，欢迎收听今天的节目，首先我必须得说在GPT的帮助下，节目的产出速度确实会得到极大的提升，毕竟很多的内容整理和准备的过程都可以通过GPT的处理得到极大的精简，例如对于词汇的整理和分析的过程，还有就是能够生成支持多角色文本转语音所需要的SSML脚本。

相信大家在上一期的节目中应该能够非常明显的感受到文本转语音的痕迹，毕竟因为时间非常的仓促，同时为了实现多角色的转换，我使用了相对熟悉的google cloud text to speech服务，但可能因为我的操作不够熟练，导致了一些问题，例如在转换的过程中，会出现一些不自然的连贯，同时对于停顿的处理也较为生硬。所以这一次的节目中，我们尝试使用了微软的语音合成服务，也让大家体验下不同的语音合成服务带来的不同体验。

好了言归正传，作为一个帮助自己提升英语能力的项目，这次的音频内容其实是对上期中Emma所创建的EmpowerME项目的延续，当然所有的内容也都是GPT所生成的，说实话我还是很惊讶GPT编故事的能力的，同时我在文本的准备上也做了一些调整以更利于学习中参考，下面就让我们继续感受GPT扯淡的能力吧，哈哈。Emma的故事还在继续。。。

为了便于学习，我会将所有GPT生成的文本内容都放出来，这样便于对照。

hello 大家好，欢迎收听今天的节目，这一期的节目我们来尝试一些不一样的，算是对于未来播客模式的一种探索了。其实我的动机非常的简单，那就是能够按照我希望的方式来提升自己的英语水平，而目前最大的障碍对于我来说就是如何能够相对精准的提升我的工作词汇量，所以我想到了这样一个办法，寻找一个科技类的文章，让GPT能够进行适当的总结以确保我对于文章的核心理解是相对准确的，同时我需要GPT来帮我识别那些对于我的工作真正有帮助的词汇，GPT需要对这些词汇进行解释，并给出例句。我相信这是大家都能想到同时也一定是最为简单实用的方案了。

不过对于我而言，我一直遵循着学习英语从听开始的原则，因此想要学习这些词汇，单纯的依靠GPT的整理就先得不够了，我必须将他们转换成我所希望的真的能够帮助我学习的形式，就是通过GPT来帮助我生成一些文章，然后我再去听这些文章，这样就能够提升我的工作词汇量了。所以今天我们就来尝试一下。今天内容的开始其实是我在Medium上面看到了一个标题为“31 Business Ideas for 2023” 这样的一篇文章，我其实对于文章的内容是不博爱有什么太大的希望的，结果自然也没有太出乎意料，不过既然看了，就还是以此作为开始吧。所以呢，我就让GPT按照之前我们说的方式开始了工作，那么我们就来看看GPT生成的内容吧。

距离上一次的播客录制已经过去了157天，这100多天里面我其实也体验了不少非常有趣的东西，但就是提不起兴趣来和大家详细的说说，直到这样的一个东西出现了，那就也是价格高达4399的airpods max。所以今天我们就来一起聊聊苹果最新的airpods max。

首先必须得说4399的airpods max真的非常贵，而且他一定不是适合所有用户的，甚至可以说是只属于小众用户的，所以我并不推荐大家在没有想清楚之前去购买这样的产品，毕竟花费4399去购买一款冬季限定的耳罩只要是个正常人都应该觉得亏。也正因此，我在这里尝试把一些我体验的结论先告诉大家，算是帮大家省钱了。

其实已经有点记不太清楚停更几个星期了，因为总能找到理由让自己停止下去，但是这不是我希望的，所以即便是在周日晚上的11点，我也会再次的打开话筒录制这新的一期。在过去停更的几周里，我自己感觉发生了很多的变化，我生活中不可或缺的F1回归了，乐队夏天2的开播几乎快要成为了我再次停更的理由。但是我真的想和大家聊聊天，去分享我所感受到的生活的变化，也许你不会喜欢这一期的内容，他显得比较随意，但我真的用心了。

首先来名词解释一下，WWDC的全称是World Wide Developers Conference，翻译过来就是全球开发这个大会，所以从字面的意思上其实已经非常的清晰的传递出来的了，这就是一个面向开发者的大会。其实一致很困惑，不知道从什么时候开始作为一个普通消费者的我们开始如此的关注一场Apple举办的开发者大会了呢？

另外这次的大会上，苹果宣布Mac产品将会开始使用A系列的苹果自研芯片，那么使用苹果自己芯片的Mac会和目前使用Intel芯片的Mac有啥区别？特别是作为一个普通消费者，我需要在意这个吗？

Sitdownplz改版啦，从本期的节目起，我们在一起节目中除了固定话题的讨论沟通以外，还有两个定期的栏目《花农的一周》以及《每周一物》，希望大家喜欢。

微信最近增加了“拍一拍”的功能，大家觉得是否使用呢？微信这样的创新是否算是产品力的体现呢？我们作为一个和微信的用户，是充当了产品实验的小白鼠还是迎接了微信切实的解决我们的痛点呢？其实作为一个普通人我没什么资格去评价微信产品设计上面的取舍，但是作为一个用户我希望我们能够使用更好的产品，我希望大家能够对于产品的好坏有自己的判断能力和依据，我们为好产品买单，对坏产品say no。

欢迎大家关注SitDownPlz的微博：Plzsitdown。

借着智美的酒劲，我开始这期迟到的节目，至于原因，那就是因为我最近当起了园丁。之前的节目中提到了，我和老婆搬到了顺义，所以我们也拥有了一个属于我们自己的花园。其实在搬来之前，我们对于花园这个事情是没有什么概念的，同时自己在之前也从来没有种过什么植物，那是为什么对于种植物这件事情突然热情了起来了呢？我借用在微博上面看到的一句话来试着表达一下：“生活其实需要一点点条理带来的安全感，一点点专注带来的成就感，一点点新鲜带来的生机感。”

这么zuo的话我是说不出来的，只是引用一下罢了，当然折起节目中还有两首非常好听的歌曲，喜欢的话关注我们的微博：Plzsitdowm
