Overview of Noisy Student Training 1. Self-training是最简单的半监督方法之一，其主要思想是找到一种方法，用未标记的数据集来扩充已标记的数据集。 算法流程如下： （1）首先，利用已标记的数据来训练一个好的模型，然后使用这个模型对未标记的数据进行标记。 （2）然后，进行伪标签的生成，因为我们知道，已训练好的模型对未标记数据的所有预测都不可能都是好的，因此对于经典的Self-training，通常是使用分数阈值过滤部分预测，以选择出未标记数据的预测标签的一个子集。 （3）其次，将生成的伪标签与原始的标记数据相结合，并在合并后数据上进行联合训练。 （4）整个过程可以重复n次，直到达到收敛。 What is Noisy Student? .
