Robust Identification of Target Genes and Outliers in Triple-negative Breast Cancer Data [PDF]

open access: yes, 2018
Correct classification of breast cancer sub-types is of high importance as it directly affects the therapeutic options. We focus on triple-negative breast cancer (TNBC) which has the worst prognosis among breast cancer types.

Multivariate Outlier Detection in Applied Data Analysis: Global, Local, Compositional and Cellwise Outliers [PDF]

open access: yesMathematical Geosciences, 2020
AbstractOutliers are encountered in all practical situations of data analysis, regardless of the discipline of application. However, the term outlier is not uniformly defined across all these fields since the differentiation between regular and irregular behaviour is naturally embedded in the subject area under consideration. Generalized approaches for

Robust principal component analysis for accurate outlier sample detection in RNA-Seq data

open access: yesBMC Bioinformatics, 2020
Background High throughput RNA sequencing is a powerful approach to study gene expression. Due to the complex multiple-steps protocols in data acquisition, extreme deviation of a sample from samples of the same treatment group may occur due to technical ...

Subgroup and outlier detection analysis [PDF]

open access: yesBMC Bioinformatics, 2013
Background High-dimensional biological data presents the opportunity to discover novel forms of biological heterogeneity, such as overexpression or suppression of expression of a particular gene in a subset of a cohort. This novel biological heterogeneity appears in the data as outliers or distinct subgroups.

Outlier Denoising Using a Novel Statistics-Based Mask Strategy for Compressive Sensing

open access: yesRemote Sensing, 2023
Denoising is always an important step in seismic processing, in order to produce high-quality data for subsequent imaging and inversion. Different types of noise can be suppressed using targeted denoising methods.

A taxonomy framework for unsupervised outlier detection techniques for multi-type data sets [PDF]

open access: yes, 2007
The term "outlier" can generally be defined as an observation that is significantly different from the other values in a data set. The outliers may be instances of error or indicate events.

Feature importance for machine learning redshifts applied to SDSS galaxies [PDF]

open access: yes, 2015
We present an analysis of importance feature selection applied to photometric redshift estimation using the machine learning architecture Decision Trees with the ensemble learning routine Adaboost (hereafter RDF).

Outlier-resilient complexity analysis of heartbeat dynamics [PDF]

open access: yesScientific Reports, 2015
AbstractComplexity in physiological outputs is believed to be a hallmark of healthy physiological control. How to accurately quantify the degree of complexity in physiological signals with outliers remains a major barrier for translating this novel concept of nonlinear dynamic theory to clinical practice.
