What is Cross Validation in Machine learning? Types of Cross Validation
WebApr 13, 2024 · Cross-validation is a statistical method for evaluating the performance of machine learning models. It involves splitting the dataset into two parts: a training set and a validation set. The model is trained on the training set, and its performance is evaluated on the validation set. WebJun 27, 2014 · If you have an adequate number of samples and want to use all the data, then k-fold cross-validation is the way to go. Having ~1,500 seems like a lot but whether it is adequate for k-fold cross-validation also depends on the dimensionality of the data (number of attributes and number of attribute values). china pediatric isolation gowns manufacturers
