I recently had a lot of fun putting together a talk for mcubed london a new conference on artificial intelligence and machine learning.
They certainly ran a great conference.
My talk was about the concept of progressive complexity in machine learning, to produce a practical pipeline for different levels of complexity on different capacity systems, with differing bandwidth characteristics. In simple terms, you can do a lot more when you have a gpu in the cloud than you can on a raspberry pi.
There is even a video for those who want to make sense of the slides.
