Fluctuation-based outlier detection [PDF]

open access: yesScientific Reports, 2023
Outlier detection is an important topic in machine learning and has been used in a wide range of applications. Outliers are objects that are few in number and deviate from the majority of objects.

A novel subspace outlier detection method by entropy-based clustering algorithm [PDF]

open access: yesScientific Reports, 2023
Subspace outlier detection has emerged as a practical approach for outlier detection. Classical full space outlier detection methods become ineffective in high dimensional data due to the “curse of dimensionality”. Subspace outlier detection methods have

A Survey of Outlier Detection Methodologies [PDF]

open access: yesArtificial Intelligence Review, 2004
Outlier detection has been used for centuries to detect and, where appropriate, remove anomalous observations from data. Outliers arise due to mechanical faults, changes in system behaviour, fraudulent behaviour, human error, instrument error or simply ...

Outlier Detection in Mendelian Randomization. [PDF]

open access: yesStat Med
ABSTRACT Mendelian randomization (MR) uses genetic variants as instrumental variables to infer causal effects of exposures on an outcome. One key assumption of MR is that the genetic variants used as instrumental variables are independent of the outcome conditional on the risk factor and unobserved confounders.

An Ensemble Outlier Detection Method Based on Information Entropy-Weighted Subspaces for High-Dimensional Data [PDF]

open access: yesEntropy, 2023
Outlier detection is an important task in the field of data mining and a highly active area of research in machine learning. In industrial automation, datasets are often high-dimensional, meaning an effort to study all dimensions directly leads to data ...

Online Bivariate Outlier Detection in Final Test Using Kernel Density Estimation [PDF]

open access: yes, 2011
In parametric IC testing, outlier detection is applied to filter out potential unreliable devices. Most outlier detection methods are used in an offline setting and hence are not applicable to Final Test, where immediate pass/fail decisions are required.
