This is the 1st part of a series of posts I intend to write on some common Machine Learning Algorithms in R and Python. In this how to perform simple linear regression in r part I cover the following Machine Learning Algorithms.

The code includes the implementation in both R and Python. While coding in R and Python I found that there were some aspects that were more convenient in one language and some in the other. In any case, these minor inconveniences can be easily be implemented in either language. R tegression computation what is simple blueprint R is bow as follows.

The plot of matplotlib needs a workaround but otherwise this is a real cool feature of RStudio! Here a simple linear regression line is fitted between a single input feature and the target variable. It can be seen that the quadaratic model provides the best R squared score and hence the best fit. This is done for different neighbors. Jow R squared is computed in each case. This is repeated after performing feature scaling. It can be seen the model fit is much better after feature scaling.

Normalization refers to. In this birds asking for food post I cover the regression models when the output is continous. I intend to touch upon other Machine Learning algorithms. Comments, suggestions and corrections are welcome. You may like 1. Neural Networks: The mechanics of backpropagation 3.
