A machine learning dataset is divided into training, validation, and test sets. Machine learning typically uses these datasets to teach algorithms how to recognize patterns in the data.... The test set is the final collection of unknown-good data against which [one] can measure the performance and make adjustments.  2, fiche 1, Anglais, - test%20dataset

During training, the training dataset is used to train the model. Periodically, data from the validation dataset is fed through the model, and the loss is calculated... By comparing the training and validation loss(and accuracy, or whichever other metrics are available) over time, you can see whether the model is overfitting.  3, fiche 2, Anglais, - validation%20dataset

The RCM... involves a repetitive sampling of a training dataset in concert with cross validation to produce a user-specified number of predictions(classified maps) of spectral units. The RCM process provides a better classification result as the final map comprises a majority classification whereby each pixel is assigned the class that occurred most frequently over the user-specified number of repetitions and the spatial uncertainty of the process is captured by a variability map(cross validation process).  2, fiche 3, Anglais, - robust%20classification%20method
