Description

I have a lot of project where I am trying to predict multiple targets at once. Atom has a bunch of nice features that I'd like to use, but I'm not sure its worth it if I have to build a separate model for each target dimension

This would be a nice extra feature indeed. Since this is a lot of work, I will consider adding this to the release after the next one. The next release is almost finished and will be out soon. After that, I'll do some digging to see how the code could be refactored to support multi-target models. I'll keep you updated in this page.

Great! I would love to contribute if I can. I've been struggling for a long time to find a package that works for my DL workflow and this package is the closest I've come. Sklearn pipelines are cool but they don't handle the validation data that well, and don't have a lot of the tooling you've put in.

Hi. Now that 4.14 has been released I was looking at the features for next release. I think it's going to be a big one (probably v5.0.0) so this seems as good a moment as any to implement the multioutput support. I added a list of things that need to be done. Feel free to pick up any of them or add your own if you think I forgot one.

Code

  • Refactor _prepare_input in basetransformer.py to accept multidim y
  • Refactor models to use classifier/regressor chain if multioutput
  • Check all transformers and adapt to multioutput where needed
  • Refactor the way metrics are calculated
  • Refactor the evaluate method
  • Add multioutput support class attribute to models
  • Add multioutput support to get_available_models

Documentation

  • Add multioutput section to user guide
  • Add multioutput example
  • Add multioutput support banner to models in API
