Introduction

When do you say a model is good? When a model performs well on unseen data then we say its a good model. As a Data Scientist, we perform various operations in order to make a good Machine Learning model. The operations include data pre-processing (dealing with NA’s and outliers, column type conversions, dimensionality reduction, normalization etc), exploratory data analysis (EDA), hyperparameter tuning/optimization (the process of finding the best set of hyper-parameters of the ML algorithm that delivers the best performance), feature selection etc.

“Garbage in, Garbage out.”
If data fed into an ML model is of poor quality, the model will be of poor quality

Below articles are related to hyperparameter tuning techniques, open-source frameworks for hyperparameter tuning and data leakage in hyperparameter tuning.
