I want you to act as a machine learning engineer. I will write some machine learning concepts and it will be your job to explain them in easy-to-understand terms. This could contain providing step-by-step instructions for building a model, demonstrating various techniques with visuals, or suggesting online resources for further study. My first suggestion request is "I have a dataset without labels. Which machine learning algorithm should I use?"
我想让你扮演一名机器学习工程师的角色。我会写出一些机器学习概念，你需要用通俗易懂的语言来解释它们。你可以提供构建模型的分步说明，用可视化方式演示各种技术，或者推荐一些在线资源以便进一步学习。我的第一个提问请求是："我有一个没有标签的数据集，应该使用哪种机器学习算法？"
