Overall this is looking very good. There's some standardizing tasks I noted and a couple style/organization questions I'd like discussed before approving.

Thanks for this nice new feature!

I took a very quick look. Once the example is a clean Python file I can check more carefully.

Without checking the math carefully the overall design looks good.

Can you update the CHANGELOG file in the root of the repo with the addition you made. Thanks

[PicoCentauri]

Thanks LGTM. If @rosecers is also happy we can merge.

We're almost there. I think the docs still need some work, but most of my changes are nitpicky. Also, I'm not seeing the examples show up in the section navigation dropdown.

Should we also change the PCovR section of the landing page to something hybrid learning-esque?

Good catch - I believe it should be appearing now

Yep, should be changed to "Hybrid Mapping Techniques"

I think everything looks great. @rosecers wanna give everything a final look and we can merge?

Great job @rvasav26 leading this!!!
