چکیده انگلیسی
The proposed method is found to lower the false alarm rate, which is one of the basic problems for the one-class SVM. Experiments show the false alarm rate is decreased from 5% to 15% among different datasets, while the detection rate is increased from 5% to 10% in different datasets with two-layer structure. The memory usage for the two-layer structure is 20 to 50 times less than that of one-class SVM. The one-class SVM uses support vectors in labeling new instances, while the labeling of the two-layer structure depends on the number of GMMs. The experiments show that the two-layer structure is 20 to 50 times faster than the one-class SVM in labeling new instances. Moreover, the updating time of the two-layer structure is two to three times less than for a one-layer structure. This reduction is the result of using two-layer structure and ignoring redundant instances.
