Validation, Overfitting, Underfitting, Overfitting Underfitting, Machine Learning.
we refer to as overfitting. So generally before implementing any model, we split our data into a training dataset and a test dataset. As in our example instead of fitting the model on 3 years, we will split the data into 2.5 years (Training dataset) and 0.5 years (Test dataset). Now we will fit the
