I am a noob at Machine Learning / Deep Learning, started learning recently. I stumbled upon Facebook's Infersent [0] and implemented this project. Infersent works really nice out of the box. For toy projects and experimentations, it is really fun to use it. The actual code which finds the closest match is less than 10 lines of Python.

I also have a demo here - http://35.200.165.252:9999/ I added some questions related to the Udacity's course I was doing. This was a side project for the course. Do note that this demo dataset is very small.
