The use of HSI images of EWs improved the overfitting phenomenon of KNN in experiment 3.1 for both statistic or network features with the result of ACC T = 100% and above 90% ACC P. For statistic features ... WebbA severe overfitting phenomenon of CNNs is that they activate completely different regions when distinguishing objects. For example, when distinguishing between dogs and cats, it is reasonable for the face region to be activated; however, if the background is activated, it means that the CNN failed to extract meaningful features.
