@lyabc0826 可以提供下您使用PNN时初始化模型时使用的参数吗

@lyabc0826 建议调低embedding_size这个参数试试(1,2,4)，另外为什么全部是连续特征呢？PNN其实并不是很适合处理大量连续特征，换言之，大量连续特征可以尝试使用普通的全连接神经网络。

谢谢。之所以全部是连续特征，是因为我们之前用xgboost，离散特征都是已经one-hot过了，为了在处理特征的时候简单，因此全部按照连续特征放进模型PNN里。再请问下，我们这种情况怎么处理比较好？用哪个模型比较适合？

@lyabc0826 deepctr的输入要求是直接将离散特征进行label encode 或者hash encode之后作为离散特征输入输入即可，对于本身就是连续型的特征可以作为连续特征使用。
建议您参考样例的处理方式对特征进行简单的预处理~
