Decision Trees
In this article we will learn about what is a Decision Tree? How it works? Why Decision Tree Overfitts & How can we resolve it?
Want to Save and Reuse a model later?
In machine learning, training a model and testing it is definitely not an end. Should we run this source code of training, tuning everything again to do predictions in future? No Need!!! We can save and reuse the same model…

Linear Regression — Part IV — Chance of Admission Prediction
Ever thought about doing magic or predict future? Here is the guide! lol! In this article lets go programming with sklearn package to explore Linear Regression and learn how to do prediction with Linear Regression. We have seen enough theories…
Linear Regression — Part III — R Squared
R Squared is one of the metrics by which we can find the accuracy of a model that we create. R squared metrics works only if the regression model is linear. SSE — Sum of Squares of Residuals (Errors) SSR is the sum…
