## Finding patterns in Predictor Variables

Finding correlated variables is very important in order to remove multicollinearity in multiple regression models.Once you know the correlated variables you can choose few from them or may be just one from them.It depends on correlation value and other factors.Let’s begin to visualize the correlation in variables in a nice plot.Open your RStudio and begin […]

## Applications of Machine Learning

Machine learning and Artificial Intelligence is future of our world. Machine learning enables us to crunch big data (Talking of Petabytes of data ???.. Yes). Machine learning is the subfield of computer science that “gives computers the ability to learn without being explicitly programmed” (Arthur Samuel, 1959). You can think of your brain.How does that […]
