Can I get sample code for this keynote？

I am a student from a non-English speaking country. I would like to get the sample code from the "Make apps smarter with Natural Language" keynote on dynamic word embeddings and custom sentence embeddings. I can't find relevant examples on google to keep learning about it. I hope the developer community can share the full text of the sample code for the Nosh app and Merch app in the video. Thanks Vivek and Doug.
