The aim of this research is just to get one acquainted with theory of Neural Networks. 

I believe that understanding the inner workings of a Neural Network is important to any aspiring Data Scientist. 

In information technology (IT), a neural network is a system of hardware and/or software patterned after the operation of neurons in the human brain. Neural networks -- also called artificial neural networks -- are a variety of deep learning technology, which also falls under the umbrella of artificial intelligence, or AI.
