cross validation in machine learning | hyper parameter optimization Part 3
what is cross-validation, and why should you care about it?
In the realm of data-driven decision-making, it's important to recognize the challenges that arise when working with limited data. One such challenge is the dilemma of partitioning data into training and validation sets, which can significantly impact the outcomes and generalization of machine learning models. The results can even be influenced by the random selection of these sets, leading to potential bias.
However, there's a powerful solution to this problem known as cross-validation, often abbreviated as CV. Cross-validation redefines how we approach model training and validation, allowing us to harness the full potential of our data without the constraints of arbitrary set selections.
In the following minutes, we'll break it down into simple terms and show you how this technique can used for hyper parameter tuning and model evaluation & selection.
