Outliers May Not Be Automatically Removed

open access: yesJournal of Experimental Psychology: General, 2022
Researchers often remove outliers when comparing groups. It is well documented that the common practice of removing outliers within groups leads to inflated type I error rates. However, it was recently argued by André that if outliers are instead removed across groups, type I error rates are not inflated. The same study discusses that removing outliers

An integrated approach for identifying wrongly labelled samples when performing classification in microarray data. [PDF]

open access: yesPLoS ONE, 2012
Using hybrid approach for gene selection and classification is common as results obtained are generally better than performing the two tasks independently.

A Geometric Estimation Technique Based on Adaptive M-Estimators: Algorithm and Applications

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021
Robust fitting is a basic technique and has been widely applied in photogrammetry and remote sensing, such as geometric correction. As known, typical robust estimators (include M-estimators, S-estimators, MM-estimators, etc.) often fail when outlier rate

SUPERVISED OUTLIER DETECTION IN LARGE-SCALE MVS POINT CLOUDS FOR 3D CITY MODELING APPLICATIONS [PDF]

open access: yesISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2018
We propose to use a discriminative classifier for outlier detection in large-scale point clouds of cities generated via multi-view stereo (MVS) from densely acquired images.

Geometric Cover with Outliers Removal.

open access: yes, 2021
We study the problem of partial geometric cover, which asks to find the minimum number of geometric objects (unit squares and unit disks in this work) that cover at least (n-t) of n given planar points, where 0 ≤ t ≤ n/2. When t = 0, the problem is the classical geometric cover problem, for which many existing works adopt a general framework called the

A Multi-Frame Superposition Detection Method for Dim-Weak Point Targets Based on Optimized Clustering Algorithm

open access: yesRemote Sensing, 2023
Long-range surveillance and early warning of space targets are significant factors in space security. Under remote observation conditions, the energy performance of the target is weak and subject to environmental and imaging process contamination.
