SVDD的主要思想是:首先,通过非线性映射将原始训练样本x,映射到高维的特征空间;然后,在特征空间中寻找一个包含全部或大部分被映射到特征空间的训练样本且体积最小的超球体(最优超球体);最后,通过非线性映射,如果新样本点在特征空间中的像落入最优超球体内,则该样本被视为一个正常点;否则,如果新样本在特征空间中...

Support vector data description (SVDD) is a data description method that can give the target data set a spherically shaped description and be used to outlier detection or classification. In real life the target data set often contains more than one class of objects and each class of objects ...
