I have a model which is trained on stock data of one company and I want to retrain that model again on stock data of another company? Is it possible using PatchTST & if yes, please guide me how to do it.

@vivekugale9887 I adopted PatchTST on my dataset, most of the work is adding a dataloader.
- You would need to create a new class of type Dataset.
- Implement a read_data method like
- implement a getitem method like
- Add your new class to the data factory

Hi @ikvision Thanks very much for answering this in details! Besides I would like to address a few more thoughts:
- Make your dataset csv in the same format and location of the sample datasets as described in readme file.
- For your setting I supposed that it is similar to transfer learning which is in table 5 of the paper. PatchTST can do it, and what you need to do is a 2-step process: self-supervised training on one dataset and fine-tune on the other one.
- Although it is doable, we do not recommend going with financial dataset at this time point because of the reason we mentioned in appendix A.1.1.

hi @ikvision , thank you for the quick reply. I am yet to try what you suggested to me. While searching for the incremental learning, I came across this notebook and am using the way it has mentioned the incremental learning.
