As far as regression models are concerned, there is a certain degree of level of correlation between the independent and dependent variables in the dataset that let us predict the dependent variable. In statistics, this correlation can be explained using R Squared and Adjusted R Squared. In other words, R Squared and Adjusted R…

There is nothing more powerful than a beautiful visualization. The effect of an intuitive visualization is far more satisfying than looking at a large table of data. In a previous article, we learned to plot graphs and create beautiful visualizations on-the-go with the Pandas built-in library. Pandas plot is a very handy feature when it…

In Machine Learning context, there are typically two kinds of learners or algorithms, ones that learn well the correlations and gives out strong predictions and the ones which are lazy and gives out average predictions that are slightly better than random selection or guessing. The algorithms that fall into the former category are referred to…
