“…As for the classifier design, some advanced classifiers such as support vector machine (SVM) [8], sparse representation [7,[9][10][11], and convolutional neural networks (CNN) [1,5,8] have been employed. Algorithms based on CNN [1,5,8] or other deep learning [3] have been enriched enormously. However, due to the special complexity of SAR images and shortage of data amount, these algorithms usually suffer from overfitting and local minima [2].…”
