Neural Network from Scratch in Python
What is a neural network and how does it remember things and make decisions? That’s what we examine in this video. We will explore the basic math behind the inner workings of a feed-forward neural net and I try to explain it as easily as possible. This is supposed to be a neural nets for dummies video. 🙂 And along the way, we will together implement our own neural net in Python from scratch.
If you are interested in deep learning, machine learning, ai or data science, this video might be a good start in the world of artificial neural networks for you!
