radio frequency confinement

Aiming at the problem of too high dimension of sample data leading to too much SVM studies in the researches of fault diagnose,This paper proposes a new SVM fault diagnose method based on DCT,using the "energy compaction"and"high frequency suppression"features of DCT,which used in the process of image compression.

针对故障诊断研究中,样本数据维数过高导致故障模式分类时SVM学习强度太大的问题,利用DCT方法在降噪处理时体现出"能量集中"和"高频抑制"的特性,提出一种基于DCT的SVM故障诊断方法。
