Understanding Model Selection with Cross Validation
Introduction: In machine learning, model selection plays a crucial role in creating models that generalize well to new, unseen data. One common approach to model selection is through cross-validation, a resampling method that helps estimate the performance of a model on different subsets of the dataset. This blog post will explore the concepts of cross-validation…
