This course strips neural networks to their fundamental core: math and raw Python.

You'll dive into the inner workings of backpropagation, gradient descent, and the math that powers modern neural networks. No pre-built frameworks, no black boxes. Just you, the math, and your code.

Step-by-step, you’ll build neural networks by hand and implement them from scratch. From partial derivatives to weight updates, every concept is broken down and coded in Python (no libraries like PyTorch required!). If you're looking to truly understand how machine learning works—and prove it by building your own neural network—this course is your launchpad.

The course is broken down into three main sections:

Introduction
Start by understanding the goals of the course and why backpropagation is central to modern machine learning. This section sets expectations and explains how mastering the math will give you a competitive edge.

Foundational Concepts and Simple Neural Network Implementation
Get hands-on with the theory. Learn how neural networks process data, calculate losses, and update weights using gradient descent. You'll manually compute everything—forward pass, gradients, and backpropagation—before coding a working network in Python.

Advanced Neural Network Implementation
Scale up your skills. This section walks you through implementing a deeper neural network with non-linear activation functions. You'll use advanced backpropagation techniques to train more complex models and understand how real-world neural networks are built from the ground up.

What Else Should I Know?

By becoming a ZTM member you'll not only get access to all our bootcamp courses, bytes, and projects.

But you’ll also get to join our exclusive live online community classroom to learn alongside thousands of students, alumni, mentors, TAs and Instructors.

Most importantly, you'll be learning from an industry professional (Patrik) that has actual real-world experience as an AI & Machine Learning Engineer. He teaches you the exact strategies and techniques he uses in his role.

Finally, as with all ZTM courses, this course is a living thing. It will be constantly updated as the landscape changes so you can use it as your go-to guide for building Neural Networks now and throughout your career.
