In this first part I cover the following Machine Learning Algorithms. The code includes the implementation in both R and Python. While coding in R and Python Regresion 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 squared computation in R is computed 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. How to plot simple linear regression in r R squared is computed in each case.

This is what is meant by a linear relationship after performing feature scaling. It can be seen the model fit is much better after hiw scaling. Normalization refers to.
