Cross-validation (CV) is a commonly used model validation technique in machine learning, employed to assess a model’s generalization ability on unseen data. By splitting the dataset into training, validation, and test sets, and repeatedly conducting training and evaluation, cross-validation can effectively test a model’s performance even when the data is limited. It helps evaluate generalization ability and is useful in reducing issues like overfitting and bias. Cross-validation plays a crucial role in controlling overfitting, selecting the best model, and tuning hyperparameters. In particular, it helps predict how a model will perform on new data, making it an indispensable part of modern machine learning workflows.
