说明：  支持向量数据描述（Support Vector Data Description，SVDD）是一种单值分类算法，能够实现目标样本和非目标样本的区分，通常应用于异常检测和故障检测等领域。(Support vector data description (SVDD) is a single valued classification algorithm, which can distinguish target samples from non target samples. It is usually used in anomaly detection and fault detection.)
