A critical overview of outlier detection methods

A Smiti - Computer Science Review, 2020 - Elsevier
One of the opening steps towards obtaining a reasoned analysis is the detection of outlaying
observations. Even if outliers are often considered as a miscalculation or noise, they may …

Anomaly detection by robust statistics

PJ Rousseeuw, M Hubert - Wiley Interdisciplinary Reviews …, 2018 - Wiley Online Library
Real data often contain anomalous cases, also known as outliers. These may spoil the
resulting analysis but they may also contain valuable information. In either case, the ability to …

Learning with bad training data via iterative trimmed loss minimization

Y Shen, S Sanghavi - International conference on machine …, 2019 - proceedings.mlr.press
In this paper, we study a simple and generic framework to tackle the problem of learning
model parameters when a fraction of the training samples are corrupted. Our approach is …

Structure and kinematics of early-type galaxies from integral field spectroscopy

M Cappellari - Annual review of astronomy and astrophysics, 2016 - annualreviews.org
Observations of galaxy isophotes, long-slit kinematics, and high-resolution photometry
suggested a possible dichotomy between two distinct classes of elliptical galaxies. But these …

Do individual auditors affect audit quality? Evidence from archival data

FA Gul, D Wu, Z Yang - The Accounting Review, 2013 - publications.aaahq.org
We examine whether and how individual auditors affect audit outcomes using a large set of
archival Chinese data. We analyze approximately 800 individual auditors and find that they …
