摘要
针对信息不确定、不完备引起的识别证据动态变化、冲突悖论等问题,提出了一种基于证据一致性检验的目标属性序贯辨识改进方法。首先采用顺序滑动窗口构建时序证据体,再通过证据一致性检验,快速定位冲突证据并动态重构出一致性证据体,最后利用证据理论合成获得目标序贯辨识结果。经仿真数据验证表明,该方法能有效积累时序证据能量、抑制冲突悖论,提高目标属性辨识的准确性和稳定性。
Aiming at the problems of dynamic change of identification evidence and conflict paradox caused by uncertain and incomplete information,an improved sequential identification method of target attributes based on evidence consistency checking is proposed.First,the sequential sliding window is used to construct the time-sequence evidence body,then the conflict evidence is quickly located through the evidence consistency checking,and the consistent evidence body is dynamically reconstructed.Finally,the sequential identification result of the target is obtained by combining the evidence theory.The simulation results show that this method can effectively accumulate time-sequence evidence energy,restrain conflict paradox,and improve the accuracy and stabili⁃ty of target attribute identification.
