sentdex

sentdex is a Python programming channel made by Harrison Kinsley. He is the co-author of the book “Neural Networks from Scratch in Python”.

The channel has around 1,000 videos covering Python for machine learning, data analysis, finance, robotics and game development. Many are multi-part series that build a project step by step. More recent videos look at new AI models and use them to control robots. The tone is relaxed and hands-on, with lots of live coding.

Some highlights include:

This first part of the Neural Networks from Scratch series codes a single artificial neuron in plain Python.

The second part builds that neuron into a full layer, the basic building block of a neural network.

This video shows a neural network trained to generate a playable driving scene, showing what AI models can learn.

The channel has over 1.4 million subscribers.

AI and machine learning now appear across engineering, from predicting faults in machines to controlling robots. sentdex shows how these systems work under the surface, rather than treating them as magic. It suits students heading towards computer science, software engineering or robotics who are comfortable with some coding. The Neural Networks from Scratch series is the best starting point, as it explains the maths alongside the code. Students with GCSE level maths and some Python can follow the early parts.
