2.3.3. Test Dataset

In test set-1, the test subject (skier 4) performs only one of the techniques of one of the XC-skiing styles repeatedly on the flat course. It has 8 files (one file for each technique of the classical and skating styles) and resembles the training data. Thus, its preprocessing is performed analogously to the training data. Similarly, the test set-2 resembles the validation data and its preprocessing is performed analogously to the validation data. Thus, 8 tensors are obtained for test set-1 and 1 for the test set-2. Table 6 contains more information about the 2 types of test sets.
