Nettet22. mai 2024 · The k-fold cross validation approach works as follows: 1. Randomly split the data into k “folds” or subsets (e.g. 5 or 10 subsets). 2. Train the model on all of the data, leaving out only one subset. 3. Use the model to make predictions on the data in the subset that was left out. 4.
