Google open-source TensorFlow

Recently, when I was attending AINL-ISMW FRUCT 2015 conference, I found out that Google open-sourced TensorFlow. That is cool, but may provoke some questions. Here, I try to answer some of them. It is definitely not the same as, say, cloud-based machine-learning service (like, for example, Azure ML is). It is a machine-learning library using data flow graphs to build models. The main purpose of the library is to create models to solve various NLP and image recognition tasks.
