One of the most essential concepts to be clarified before embarking on the journey of machine learning is linear regression. It is a simple concept both mathematically and to visualize practically. However still when I came across below video I thought a 5th grade kid could also understand linear regression. :)
So here is the video:
Introduction to Linear Regression
What is regression?
Regression: Modelling target value using independent predictors. Helps in forecasting and finding out cause and effect relationship between variables. Regression techniques differ based on the types of relationship between dependent and independent variable and the number of independent variables.
Linear regression: The number of independent variables is one and there is a linear relationship between the independent(x) and dependent(y) variable.
