Introduction to Neural Networks -- Part 2

This is the second part of the neural network tutorial. The first part can be found here: https://link.medium.com/YCEAECVp0W Now that we have seen how a neural network is represented, we can go on to see how exactly it works. Since there are many layers having many neurons, there exists a complex set of weights to get an output from some input variables. Each weight in this network can be changed and hence there are countless configurations a neural network can have.
