Machine learning models

Hi! I’m new to Rasa. I am a machine learning engineer and want to understand and maybe contribute to the NLU part. Where can I find documentation about the models used and all the technical details about the NLP/NLU part ?

Thank you,

You have a good start in the documentation -

Perhaps also look through the code at GIthub - It will give you structure on how rasa is built.
