关于QIKT损失函数的疑惑

[auakerman]

def train_one_step(self,data,process=True,return_all=False):
    outputs,data_new = self.predict_one_step(data,return_details=True,process=process)
    # all 
    loss_q_all = self.get_loss(outputs['y_question_all'],data_new['rshft'],data_new['sm'])
    loss_c_all = self.get_loss(outputs['y_concept_all'],data_new['rshft'],data_new['sm'])

作者你好，我看outputs中的y_question_all和y_concept_all好像是t时刻的预测值，而rshft是t+1时刻的真实值。 为什么要用这两个值做损失？请问是我哪里理解错误了吗

Do you understand now, I also have some doubts, whether this is related to time series forecasting
