Adapt the backbone model in example.py for univariate and multivariate time series forecasting (Informer datasets)

[Giua25]

I am interested in time series forecasting and I would like to use S4D as in example.py to run it in external repositories.
How should the S4Model class in example.py be modified in order to correctly process time series datasets such as ETTh, if this is possible?

Thank you for any help.
