Adversarial Subspace Generation for Outlier Detection in High-Dimensional Data

Jose Cribeiro-Ramallo, Federico Matteucci, Paul Enciu +4

Outlier detection in high-dimensional tabular data is challenging since data is often distributed across multiple lower-dimensional subspaces -- a phenomenon known as the Multiple…
