** The quickest way to understanding (and programming) neural networks using Python **

This course is for everyone who wants to learn how neural networks work by hands-on programming!

Everybody is talking about neural networks but they are hard to understand without setting one up yourself. Luckily, the mathematics and programming skills (python) required are on a basic levelso we can progam 3 neural networks in just over 3 hours. Do not waste your time! This course is optimized to give you the deepest insight into this fascinating topic in the shortest amount of time possible.

The focus is fully on learning-by-doing and I only introduce new concepts once they are needed.

What you will learn

After a short introduction, the course is separated into three segments – 1 hour each:

1) Set-up the most simple neural network: Calculate the sum of two numbers.
You will learn about:

Neural network architecture
Weights, input & output layer
Training & test data
Accuracy & error function
Feed-forward & back-propagation
Gradient descent

2) We modify this network: Determine the sign of the sum.
You will be introduced to:

Hidden layers
Activation function
Categorization

3) Our network can be applied to all sorts of problems, like image recognition: Determine hand-written digits!
After this cool and useful real-life application, I will give you an outlook:

How to improve the network
What other problems can be solved with neural networks?
How to use pre-trained networks without much effort

Why me?

My name is Börge Göbel and I am a postdoc working as a scientist in theoretical physics where neural networks are used a lot.
I have refined my advisor skills as a tutor of Bachelor, Master and PhD students in theoretical physics and have other successful courses here on Udemy.

“Excellent course! In a simple and understandable way explained everything about the functioning of neural networks under the hood.” – Srdan Markovic

I hope you are excited and I kindly welcome you to our course!

Frequently Asked Questions

How long do I have access to the course materials?

You can view and review the lecture materials indefinitely, like an on-demand channel.

Can I take my courses with me wherever I go?

Definitely! If you have an internet connection, courses on Udemy are available on any device at any time. If you don’t have an internet connection, some instructors also let their students download course lectures. That’s up to the instructor though, so make sure you get on their good side!
