问题1:请问图中328行的x_mark = x_mark.repeat(N, 1, 1)有什么作用?
这里是为了处理channel independent操作,因为把输入X的channel维度的N移到了batch上,这里x_mark也需要重复N次对齐;
问题2:请问图中340行x_list = self.pre_enc(x_list) 有什么作用呀?
这里是针对x的输入进行周期趋势的分解,分别进行处理

请问您在建模过程中,channel independent是根据效果做出的选择吗?一般来说是0还是1呢?

请问这里的channel independent借鉴的是哪篇论文呢

通常针对具有复杂关系的多元变量,例如PEMS数据集等采用channel dependent;其余场景采用channel independent方案较好;具体可以参考这个论文https://arxiv.org/abs/2304.05206

好的,感谢。如果我想通过变量ABC来预测ABC+D的变化,由于输入没有D,是不是只能选择channel dependent了?

你好,如果是协变量预测(如上所述,用变量ABC来预测ABC+D的)确实是需要选择channel dependent
