WebDec 24, 2024 · Cross-Validation has two main steps: splitting the data into subsets (called folds) and rotating the training and validation among them. The splitting technique commonly has the following properties: Each fold has approximately the same size. Data can be randomly selected in each fold or stratified. WebMar 22, 2024 · Note: Data ranges and number of data points for all data, data range to be used as training data for leave-one-out cross-validation (LOOCV) and twofold cross-validation (CV), and the dose distance from the training data to the test dose point, were tabulated. Of note, the test dose is numerically identical to the all data dose range, as the ...
