Maybe you can check Hierarchical Forecasting? https://github.com/Nixtla/hierarchicalforecast

Thanks, but I'm not sure the focus of the Hierarchical Forecasting is to capture the interdependencies. Moreover, there's no hierarchy in the scenario I'm talking about. If you consider a product portfolio, I'm talking about multiple products (with interdependencies) but no categories, countries or other groupings.

Hi @Arthur, we added a graph multivariate model in Neuralforecast, the

stemgnn

model. We still dont have a specific tutorial for it, but the syntax is the same as other models.

Ok, thanks for the info Cristian!

If you have product names or descriptions you could use a llm(or really any method but llms are all the rage) to generate embeddings and pass that to MLForecast, alternatively you could generate time series features and pass that as well. Probably won’t give you too much over stat but you could give it a shot.

I was mostly curious if there was a simple way to explore training on multiple series as Darts provides: https://unit8co.github.io/darts/examples/01-multi-time-series-and-covariates.html#Training-on-Both-Air-Traffic-and-Milk-Series
