Machine learning is one of the fastest growing fields, and we cannot emphasize enough about its importance. This course aims to teach one of the fundamental concepts of machine learning, i.e., Neural Network. You will learn the basic concepts of building a model as well as the mathematical explanation behind Neural Network and based on that; you will build one from scratch (in Python). You will also learn how to train and optimize your network to achieve a better result.

Make Your Own Neural Network in Python

## Test the network

Now that we’ve trained the network, at least on a small subset of 100 records, we want to test how well that worked. We'll do this against the second dataset, the training dataset. 

First we need to get the test records, and the Python code we'll use is very similar to what we used to get the training data:
