A Local Density-Based Approach for Local Outlier Detection

open access: yes, 2016
This paper presents a simple but effective density-based outlier detection approach with the local kernel density estimation (KDE). A Relative Density-based Outlier Score (RDOS) is introduced to measure the local outlierness of objects, in which the ...

Critical Review for One‐Class Classification: Recent Advances and Reality Behind Them

open access: yesWIREs Data Mining and Knowledge Discovery, Volume 16, Issue 1, March 2026.
This review presents a new taxonomy to summarize one‐class classification (OCC) algorithms and their applications. The main argument is that OCC should not learn multiple classes. The paper highlights common violations of OCC involving multiple classes.

Apolipoprotein E Deficiency Impairs Human Microglial Proliferation Accompanied by Elevated Cellular Oxidative Stress

open access: yesJournal of Cellular and Molecular Medicine, Volume 30, Issue 6, March 2026.
ABSTRACT The APOE gene, which encodes Apolipoprotein E (ApoE), is the strongest genetic risk locus for Alzheimer's disease (AD). A substantial fraction of AD risk genes converges on pathways controlling lipid metabolism and immune regulation, in which microglia serve as a central integrative hub in the brain.

Towards Real-Time Detection and Tracking of Spatio-Temporal Features: Blob-Filaments in Fusion Plasma

open access: yes, 2016
A novel algorithm and implementation of real-time identification and tracking of blob-filaments in fusion reactor data is presented. Similar spatio-temporal features are important in many other applications, for example, ignition kernels in combustion ...

Deviation‐Guided Attention for Semi‐Supervised Anomaly Detection With Contrastive Regularisation

open access: yesCAAI Transactions on Intelligence Technology, Volume 11, Issue 1, Page 66-82, February 2026.
ABSTRACT Anomaly detection (AD) aims to identify abnormal patterns that deviate from normal behaviour, playing a critical role in applications such as industrial inspection, medical imaging and autonomous driving. However, AD often faces a scarcity of labelled data. To address this challenge, we propose a novel semi‐supervised anomaly detection method,

A Novel Wind Power Outlier Detection Method with Support Vector Machine Optimized by Improved Harris Hawk

open access: yesEnergies, 2023
The accurate detection of wind power outliers plays a crucial role in wind power forecasting, while the inherited strong randomness and high fluctuations bring great challenges to this issue.

The impact of Hnrnpl deficiency on transcriptional patterns of developing muscle cells

open access: yesFEBS Open Bio, Volume 16, Issue 1, Page 178-198, January 2026.
We performed nanopore whole‐transcriptome sequencing comparing RNA from Hnrnpl‐knockdown versus control C2C12 myoblasts to investigate the contributions of Hnrnpl to muscle development. Our results indicate that Hnrnpl regulates the expression of genes involved with Notch signaling and skeletal muscle, particularly splicing patterns of specific muscle ...

Noncausal AR‐ARCH Model and Its Applications to Financial Time Series

open access: yesInternational Journal of Finance &Economics, Volume 31, Issue 1, Page 1424-1443, January 2026.
ABSTRACT We extend the noncausal autoregressive models by introducing noncausality into the variance component, allowing the volatility to depend on future prices as well. We refer to this model as the noncausal AR‐ARCH model, and it enables us to account for shocks arising from market agents who possess more information and engage in forward‐looking ...
