For those interested, I recently wrote a guide on using neural networks for NLP[1].

I wrote the guide with the explicate goal of trying to help the people understand NLP (sentence classification) without the need to understand the math.

I cover word embeddings:

As well as FastText:

Hope someone finds it useful.
