- In this case, the SVM had been trained on 100 images (50 healthy, 50 ill patients) acquired by Operator 1 and validated using independent sets of the same size of images obtained by Operator 1 or 2. The performance of the classifier is generally better with Operator 1 on data collected on device 1 (which originated the data) although there are variations in performance. Both operators used both devices to acquire data.
