Gradient Descent - Simply Explained! ML for beginners with Code Example!
Показать описание
In this video, we will talk about Gradient Descent and how we can use it to update the weights and bias of our AI model. We will learn how to minimize the average loss of our model, and get a warm introduction to "epochs" and "learning rate"!
We will of course also see a working example of the math behind Gradient Descent, and learn how to implement it with code by using our superior Python skills! 🐍🐍🐍
Before we dive in, make sure you are proficient with the previous topics of my AI series - Perceptron, Weights, Input, Weighted Sum, Target, Prediction, Activation Function, Loss Function & Cross-Entropy Loss.
If you are 🆕 new 🆕 to these concepts, please watch my other tutorials first (links below):
