WebJan 23, 2024 · The process here is: For both X and Y, I want a training set, validation set, and testing set. The training set is the first 35 samples in the time series. The validation set is the next 15 samples. The test set is the final 10. The train and validation sets are use to determine the optimal alpha parameter within Ridge regression. WebTSCV: Time Series Cross-Validation. This repository is a scikit-learn extension for time series cross-validation. It introduces gaps between the training set and the test set, which mitigates the temporal dependence of time series …

WebThe remedy for this is to leave a gap between the test sample and the training samples, on both sides of the test sample. The reason why you also need to leave out a gap before the test sample is that dependence is symmetric when you move forward or backward in time (think of correlation).
