摘要
针对支持向量机在故障诊断中不能区别不同误判所造成损失不同的缺点,提出并应用了可变风险支持向量机,对最优分类面进行重新设计,使之更符合实际情况,并在柴油机故障诊断中取得了很好的效果。
To the drawbacks of the support vector machines can not distinguish the different loss by different miscarriage of justice, the vario-risk support vector machines is proposed, redesigned the optimum classified face,to make it be true of actual condition. It is applied in the fault diagnosis of the diesel engine successfully.
