WebMay 21, 2024 · “In simple terms, Cross-Validation is a technique used to assess how well our Machine learning models perform on unseen data” According to Wikipedia, Cross-Validation is the process of assessing how the results of a statistical analysis will generalize to an independent data set.
WebJan 30, 2024 · Cross validation is a technique for assessing how the statistical analysis generalises to an independent data set.It is a technique for evaluating machine learning models by training several models on subsets of the available input data and evaluating them on the complementary subset of the data. WebCross validation, used to split training and testing data can be used as: from sklearn.model_selection import train_test_split. then if X is your feature and y is your label, you can get your train-test data as: X_train, X_test, y_train, y_test = train_test_split (X, y, …
