Outlier Detection

196 papers with code • 11 benchmarks • 11 datasets

Outlier Detection is a task of identifying a subset of a given data set which are considered anomalous in that they are unusual from other instances. It is one of the core data mining tasks and is central to many applications. In the security field, it can be used to identify potentially threatening users, in the manufacturing field it can be used to identify parts that are likely to fail.

Learning Representations of Ultrahigh-dimensional Data for Random Distance-based Outlier Detection

xuhongzuo/DeepOD 13 Jun 2018

However, existing unsupervised representation learning methods mainly focus on preserving the data regularity information and learning the representations independently of subsequent outlier detection methods, which can result in suboptimal and unstable performance of detecting irregularities (i. e., outliers).
