A Unified Subspace Outlier Ensemble Framework for Outlier Detection in High Dimensional Spaces
Zengyou He, Xiaofei Xu, Shengchun Deng
The task of outlier detection is to find small groups of data objects that are exceptional when compared with rest large amount of data. Detection of such outliers is important for…
An Optimization Model for Outlier Detection in Categorical Data
