@giffmana Most comprehensive Transformers slide deck I have encountered so far. Thanks for sharing!

[Lucas Beyer (bl16) @giffmana]

My Transformer tutorial slides are now available at https://t.co/aYfnVKPDjT

I'll append recordings to this thread as I get them.

If you want to use some of the slides for your lecture, you may, as long as you credit me.

If you'd like me to give the lecture: maybe; e-mail me.
