about the best_beta、best_alpha

[XDS0rryMaker]

为什么best_beta、best_alpha的生成能够用到测试数据的pse_keys？超参数的生成不是应该和测试数据无关吗？

You can perceive beta and alpha as regular parameters rather than hyperparameters. The experiment only utilizes the features and pseudo labels of the test data, which is a prevalent approach in semi-supervised learning. Alternatively, you can also keep beta and alpha fixed; however, this might slightly compromise the results.
