Hi @stillwaterman , thanks for your attention! Yes your understanding is correct.
The two folders here are both the latest versions of PatchTST. PatchTST_supervised is developed based on some previous papers like Informer, Autoformer, FEDformer, DLinear... we here use the same codebase to make a fair comparison. PatchTST_self_supervised is developed based on tsai repo, which is another popular codebase of building time series ai models.
Thanks for your immediate reply, I understand!
Hi, I got a question about the head of self-supervised PatchTST. In my opinion, self-supervised PatchTST use a D × P linear layer(self.create_pretrain_head or PretrainHead) to do the pretrain process,then remove this head and attach a PredictionHead(Flatten_Head) to do end-to-end finetune or linear probing, am I right? By the way, there are two versions of PatchTST in PatchTST_self_supervised and PatchTST_supervised, which one is the lastest version?
