许多行业专家认为，无人监督学习人工智能的下一个前沿，这可能是人工智能研究的关键，即所谓的一般人工智能。
由于世界上大多数数据都没有标记，因此无法应用传统的监督学习;这就是无监督学习的用武之地。
无监督学习可以应用于未标记的数据集，以发现埋藏在数据深处的有意义的模式，人类几乎不可能发现这些模式。
作者AnkurPatel使用两个简单的，生产就绪的Python框架-scikit-learn和使用Keras的TensorFlow，提供了有关如何应用无监督学习的实用知识。
通过提供实际操作示例和代码，您将识别难以发现的数据模式，获得更深入的业务洞察力，检测异常，执行自动特征工程和选择，以及生成合成数据集。
您只需要编程和一些机器学习经验即可开始使用。

在日常工作中，钉钉打卡成了我生活中不可或缺的一部分。然而，有时候这个看似简单的任务却给我带来了不少烦恼。 每天早晚，我总是得牢记打开钉钉应用，点击"工作台"，再找到"考勤打卡"进行签到。有时候因为工作忙碌，会忘记打卡，导致考勤异常，影响当月的工作评价。而且，由于我使用的是苹果手机，有时候系统更新后，钉钉的某些功能会出现异常，使得打卡变得更加麻烦。 另外，我的家人使用的是安卓手机，他们也经常抱怨钉钉打卡的繁琐。尤其是对于那些不太熟悉手机操作的长辈来说，每次打卡都是一次挑战。他们总是担心自己会操作失误，导致打卡失败。 为了解决这些烦恼，我开始思考是否可以通过编写一个全自动化脚本来实现钉钉打卡。经过一段时间的摸索和学习，我终于成功编写出了一个适用于苹果和安卓系统的钉钉打卡脚本。
