Conclusion

Congratulations. You can successfully create a full-fledged Neural Network architecture. The network has many activation functions, can input 2-dimensional data with any shape, and can be as deep or as wide as you need.

I understand that all of the code and the mathematical backgrounds are tough for you. In real life, you do not have to do any of these at all. In the next lesson, we will learn TensorFlow. Then you will realize how easy it is to create and train a deep learning model within as small as 10 lines of code.
