Split the dataset into K equal partitions (or "folds") So if k = 5 and dataset has 150 observations. Each of the 5 folds would have 30 observations. Use fold 1 as the testing set and the union of the other folds as the training set. sunny side up brick nj
K-fold cross-validation with validation and test set
WebNov 26, 2024 · The answer is Cross Validation. A key challenge with overfitting, and with machine learning in general, is that we can’t know how well our model will perform on new data until we actually test it. ...
