Working principle of multitraining and prediction ( means that the first six datasets were used for prediction validation, and the rest of the data were used as the training model; means that the second six datasets were used for prediction validation, and the rest of the data were used as the training model; …, means that the last six datasets were used for prediction validation, and the rest of the data were used as the training model).
