汉默博士仔细检查了《香蕉男孩》的分段图像，意识到裂纹图案意味着墨水的存在。

Mr Nader used a different approach, starting with " unsupervised pretraining" on the segmented images, asking a machine-learning system to find whatever patterns it could, with no external hints.

纳德先生使用了一种不同的方法，从对分割图像进行“无监督预训练”开始，要求机器学习系统在没有外部提示的情况下找到它能找到的任何模式。
