Hi @Manuel. Yes, the time series are padded with zeros at the beginning

Thanks @Cristian (Nixtla)! If short sequences have exogenous variables (e.g. futr_exog), how are they handled? Do they get filled with zero as well?

all temporal variables are padded at the beginning of the time series
m
So, theoretically, instead of letting everything automatically pad with zero, might it be better to manually pad the time series with zero and create an exogenous binary variable such as "is_padding" to indicate to the model that that is a padding?
