Abnormal Signal Detection Method Based on Incomplete Data
Shi Ying-chuna · Jisuanji gongcheng · 2011
A new technique for the problem of incomplete data in abnormal signal detection system is proposed.Getting inspiration from the geometry,the new method compares the incomplete date with normal data,it presents a computation method of abnormal probability.With the abnormal probability,some abnormal signals can be detected directly,and the other incomplete data can be arranged.The algorithm decreases the workload and makes good use of calculation resources.Experimental result shows that when some parameters are lost,the method can get the reasonable abnormal probability of the incomplete data.
