WebDec 21, 2012 · Of the k subsamples, a single subsample is retained as the validation data for testing the model, and the remaining k − 1 subsamples are used as training data. The cross-validation process is then repeated k times (the folds), with each of the k subsamples used exactly once as the validation data. WebData validation is an essential part of any data handling task whether you’re in the field collecting information, analyzing data, or preparing to present data to stakeholders. If data isn’t accurate from the start, your results definitely won’t be accurate either. That’s why it’s necessary to verify and validate data before it is used.
