Hi. Thanks for the amazing paper and architecture.
I was trying to find out how many stacks in a generic model you used and I noticed in your paper:
"The original NBEATS configuration includes only one
generic stack with dozens of blocks, while our proposed model includes both the generic and
exogenous stacks, with the order determined via data-driven hyperparameter tuning. We
refer to this configuration as the NBEATSx-G model."
That confused me, because in the original NBEATS paper in a table listing N-BEATS-G hyperparameters (Table 18.) authors claim to have used 30 stacks with 1 block in each. Did you assume they had mismatched the numbers? To me, 30 blocks and 1 stack seems to be more reasonable as well.
Can you confirm that you used just 2 stacks (one generic, one exogenous)? Additionally, do you think it would make sense to add more stacks (idk what configuration would be best)?
