Graph-based Selective Outlier Ensembles

2018-04-17 · Hamed Sarvari, Carlotta Domeniconi, Giovanni Stilo

An ensemble technique is characterized by the mechanism that generates the components and by the mechanism that combines them. A common way to achieve the consensus is to enable each component to equally participate in t…
