Hi, thank you for your work! I have some questions about it.

1. You don't use the validation set, do you? So the experiment only has two parts: training and testing, is it?
2. Why the 'self.input_P_cor' and 'self.input_N_cor' in 'test_model' is '[0,0]', rather than feed it the same as ' train_model'?

I am looking forward to your reply! Thank you so much!

您好！从您的数据处理程序看，您的数据应该没有完全提供啊，打开数据也都是用户id和对应的项目id,没有评分一栏的数据。这样的话，用不上啊。
