Should we also add Time-LLM? HINT?

[cchallu]

Thanks for this! We should wait a few days; we are adding the iTransformer and MLPMultivariate. Can you also add them once they are in the main branch?

[jmoralez]

I think we can move forward with this now and add BiTCN (#958).

[candalfigomoro]

Added more models:

• iTransformer
• MLPMultivariate
• BiTCN
• Time-LLM

Not sure about what to do with HINT, since it basically wraps other models.

TiDE can also be added when merged.

[jmoralez]

We just merged DeepNPTS (#990)

Thanks @candalfigomoro! Small comments:

• Probabilistic forecasts are not supported for multivariate models.
• Missing TSMixerx

[candalfigomoro]

@elephaint I think HINT is the only missing one. It's a little bit special. It should be multivariate but probabilistic forecast (!), no point forecast, yes Auto, exog depends on the base model. Structure also depends on the base model.

LGTM, thanks!

Agree, that's a bit an odd one. I'm playing with more of these types of weird ones, so it's still on my list. I think maybe a 'meta-model' category would make sense sometime.
