Weban alternative method of cross-validation, which we dub 'h-block cross-validation', that can handle general forms of dependence. The idea is a simple one. Rather than remove the single case (Xi, . . ., Xi+k) when calculating the ith least-squares estimate, remove as well a block of h cases from either side of it. WebHere is a visualization of cross-validation behavior for uneven groups: 3.1.2.3.3. Leave One Group Out¶ LeaveOneGroupOut is a cross-validation scheme where each split holds out samples belonging to one specific group. Group information is provided via an array that encodes the group of each sample.

WebJul 11, 2024 · The 10-fold cross-validation of the model was performed on the training set, and the data from the three remaining patients were used for the blindfold validation. The reported blindfold validation performance was even higher than in the 10-fold validation (accuracy 99.77% vs. 98.51%), which can be due to the small size of the validation set.
