MachineX: What is K-Fold Cross Validation?

March 31, 2019March 31, 2019ML, AI and Data Engineeringk-fold cross validation, machine, Machine Learning, MachineX, validation

Reading Time: 3 minutes In this blog, we are going to explore and learn about K-Fold Cross Validation. K-Fold Cross Validation is a statistical method to evaluate a Machine Learning model’s performance. So, to understand what K-Fold Cross Validation is, we first need to understand what evaluating a model means, and why do we need to do that.
