WebOct 8, 2024 · The performance was assessed via nested cross-validation (CV) and cross-site CV. Accuracies ranged from 50% to 70% for surfaced-based features; from 50% to 63% for GMV; and from 51% to 68% for VBCT. The best accuracies (70%) were achieved when DL was applied to surface-based features; however, these models generalized poorly to other … WebScikit-learn TimeSeriesSplit. TimeSeriesSplit doesn't implement true time series split. Instead, it assumes that the data contains a single series with evenly spaced observations ordered by the timestamp. With that data it partitions the first n observations into the train set and the remaining test_size into the test set. WebJan 31, 2024 · Time series CV; Hold-out cross-validation.
