One class classification is a machine learning approach different from the traditional pattern recognition approach where two or more class samples are required . however in some real - life cases , we can hardly , even not , get the samples of some classes , or have to pay costly price to obtain the so - needed samples , such as in the case of machinery malfunction . and while in other cases , the sizes of samples among classes are imbalance , such as medical diagnosis
单类分类器是不同于传统模式识别的一种机器学习方法，传统模式识别方法一般需要多个类别的样本(至少两个) ，而在有些场合中，几乎无法获取多类的样本，或者获取其样本所需花费的代价非常高，比如：机器故障中我们不可能为了去获得故障样本而让机器特意产生故障；又有些场合的类别样本个数严重不平衡，比如医学上的疾病特征与非疾病特征的比例是严重不平衡的。
