To make it clear, I didn't write this code/paper, I am like you - using it.
In the open source community it is not always easy to understand each other.
I would suggest to be kinder in order to get assistance
from patchtst.
For a single step into the future, would that help
parser.add_argument('--target_points', type=int, default=1, help='forecast horizon')
The current masking in the code is random
Do you have a casual mask pytorch implementation you are considering?
from patchtst.
This does not address my question.
I was talking about run time issues
from patchtst.
Training time can be solved in many different ways - multi-gpu, larger batch size, faster data-loader...
Why do you think that causal mask is your main bottle neck?
from patchtst.
Please read the question
from patchtst.
When you have a window size of H and a causal mask you can predict H tokens in a single pass.
from patchtst.
Indeed the methods is patch based, it might to be the best fit for predicting a single data point
You might want to to use only the pre-training with patch to create embedding.
For the second stage (fine-tunning) you can have a very simple regression from embedding predicting a single time step (1 layer NN without patches)
from patchtst.
I would suggest to wait for the authors for a response.
Thank you for replying.

Thanks for asking @Eliav2479 and sorry for the late reply. Unfortunately we do not understand your question very well so we would appreciate if you could explain more of your concern. We basically agree with the solution that @ikvision proposed if you want to apply it to multiple-step prediction. Or you would just directly do multiple-step forecasting (DMS rather than IMS in this paper https://arxiv.org/pdf/2205.13504.pdf). The input is X1,...,Xt and output is Xt+1,..,Xt+T, which is done in one pass.

any estimate on how long it will take to run supervised and self-supervised learning based on default model and params.
from patchtst.
It varies on different datasets, epochs, GPU... thus it would be hard to answer. The fastest one may take half an hour while the largest model takes a day. @DIKSHAAGARWAL2015
