Most effective data science driven engines are written in python. And with most machine learning and Ai related are constructed with python therefore there is a way of integrating tensor flow in python to other Web platforms like nodejs or ruby on rails.
You haven't written a description for this talk yet. Having just a title is a great place to start, but you probably don't want to submit your talk to an event without any sort of description. All you need to do is click the edit button and fill it in. Think of the great sense of accomplishment you'll feel when you're finished.
It essentially to have a basic understanding of Machine Learning, Neural networks, Keras API from tensor flow from Google. Nodejs will be a platform I will use to demo so that I run python scripts via node and see how powerful python as a language for machine learning
