Neural Networks In Python From Scratch. Build step by step!

You will learn how to build Neural Networks with Python. Without the need for any library, you will see how a simple neural network from 4 lines of code, evolves into a artificial intelligence network that is able to recognize handwritten digits.

During this process, you will learn concepts like: Feed forward, Cost functions, Back propagation, Hidden layers, Linear regression, Gradient descent and Matrix multiplication. And all this with plain Python.

Target audience

Developers who especially benefit from this course, are:

• Developer who want to learn the mechanics of neural networks

• Developers who want to avoid using neural network libraries and frameworks

• Or developers who use frameworks but want to learn the meaning of the individual network parameters

Challenges

Many tutorials claim to start from scratch, but import external libraries or rapidly type in code and before executing even once, you are looking at 50 lines of code. When finally the code is run, you are totally lost and still stuck trying to understand line 3.

This causes many students to give up learning Neural Networks.
This course is different! It starts with the absolute beginning and each topic is a continuation of a previous example. This way, you will learn neural networks from the ground up, step by step.

What can you do after this course?

• You understand neural network concepts and ideas, like back propagation and gradient descent.

• You are able to build a neural network in any programming language of choice, without the help of frameworks and libraries.

• You understand how to better configure the network by plugging in different cost functions and adding hidden layers.

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!
