Neural networks (NN), also called artificial neural networks (ANN) are a subset of learning algorithms within the machine learning field that are loosely based on the concept of biological neural networks. Andrey Bulezyuk, who is a German-based machine learning specialist with more than five years of experience, says that "neural networks are revolutionizing machine learning because they are capable of efficiently modeling sophisticated abstractions across an extensive range of disciplines and industries." There are several types of neural networks. In this project, we are going to create the feed-forward or perception neural networks. Training the feed-forward neurons often need back-propagation, which provides the network with corresponding set of inputs and outputs.
