一旦你定义并理解了你的问题，并且消除了其中的潜在偏差来源，下一步就是构建和准
备你将在系统中使用的数据。同样，这也是一种可能无意中引入偏见的方式。
AI 中的偏差通常仅归因于用于训练模型的数据。虽然数据通常是主要的嫌疑来
源，但它并不是唯一的嫌疑。偏差可以通过特征工程、迁移学习和无数其他方式
蔓延。你经常会修复你的数据来消除偏见，但不能简单地清理数据并宣布胜利。
在创建系统时请记住这一点。我们将在本章中重点关注数据，因为这是通用工
具可以使用的地方，但同样，请尽量避免偏差仅是通过数据引入的心态！

避免数据中的偏差
并非所有数据偏差都很容易发现。我曾经参加过一次学生竞赛，参赛者使用生成对抗网
络（GAN）进行图像生成，根据面部的上半部来预测下半部的样子。那是在 COVID-19
大流行之前，但日本仍然是流感季节，许多人会戴上口罩来保护自己和他人。
这个想法是看看人们是否可以预测口罩下面的脸。对于这项任务，他们需要访问面部
数据，因此他们使用了带有年龄和性别标签的面部图像 IMDb 数据集（

）。那么问题来了，鉴于来源是 IMDb，这个数据集中的绝大多数人脸都不是日本
人。因此，他们的模型在预测我的脸时做得很好，但预测他们自己的就不好了。在没有
足够的数据覆盖率的情况下急于获得 ML 解决方案，学生们产生了一个有偏见的解决方
