Awesome, thanks for this! For the thumbnails, it might be better to use the tensor diagrams of the NNs, such as the one from the screenshot, instead of the message passing equations (that you currently have in the .png). What do you think?

1. I'm scared that the equations would not look as good as thumbnails.
2. We already have the equations in the docstrings of the methods.

Tensor diagrams can be found here: https://arxiv.org/pdf/2304.10031.pdf

I heartily agree, I just wanted to have something to test if the code works. I will update the images by EOD with the diagrams.

[ninamiolane]

Awesome, thanks for the quick answer! I can share the .svg or the .pdf of the figure with the tensor diagrams via email, if you want to be able to screenshot the diagrams easily.

[devendragovil]

Oh yeah, that would be awesome. You can mail me at govildev@gmail.com. Thanks a lot!

@devendragovil I'm converting to drafty for now, I'll let you mark it ready for review when you'd like a review. Thanks for everything!
