Linear Regression Machine Learning Algorithm

In this ML course tutorial, we are going to learn the “Linear Regression Machine Learning Algorithm in detail. we covered Simple Linear regression and Multiple Linear regression supervised regression learning algorithm by practical and theoretical intuition.
