Scalable approximate FRNN-OWA classification [PDF]

open access: yes, 2020
Fuzzy Rough Nearest Neighbour classification with Ordered Weighted Averaging operators (FRNN-OWA) is an algorithm that classifies unseen instances according to their membership in the fuzzy upper and lower approximations of the decision classes. Previous

Chronic back pain sub-grouped via psychosocial, brain and physical factors using machine learning

open access: yesScientific Reports, 2022
Chronic back pain (CBP) is heterogenous and identifying sub-groups could improve clinical decision making. Machine learning can build upon prior sub-grouping approaches by using a data-driven approach to overcome clinician subjectivity, however, only ...

One-class classifiers based on entropic spanning graphs [PDF]

open access: yes, 2016
One-class classifiers offer valuable tools to assess the presence of outliers in data. In this paper, we propose a design methodology for one-class classifiers based on entropic spanning graphs.

Passively mode-locked laser using an entirely centred erbium-doped fiber [PDF]

open access: yes, 2015
This paper describes the setup and experimental results for an entirely centred erbium-doped fiber laser with passively mode-locked output. The gain medium of the ring laser cavity configuration comprises a 3 m length of two-core optical fiber, wherein ...

Localised edge‐region‐based active contour for medical image segmentation

open access: yesIET Image Processing, 2021
Segmenting the region of interest (ROI) from medical images is a fundamental but challenging task due to the illumination change and imaging devices. Although many models based on the local region‐based active contour model (LR‐ACM) are proposed to deal ...

An Integrated Index for the Identification of Focal Electroencephalogram Signals Using Discrete Wavelet Transform and Entropy Measures

open access: yesEntropy, 2015
The dynamics of brain area influenced by focal epilepsy can be studied using focal and non-focal electroencephalogram (EEG) signals. This paper presents a new method to detect focal and non-focal EEG signals based on an integrated index, termed the focal

On Performance Analysis of a Neutrosophic Bipolar Fuzzy and Texture-Based Model for COVID-19 Detection from Chest X-Rays [PDF]

open access: yesNeutrosophic Sets and Systems
This study proposes a novel hybrid framework for rapid and accurate COVID-19 detection from chest X-ray images by integrating Neutrosophic Bipolar Fuzzy Sets (NBFS) with texture-based feature anal ysis.

M-CGH: Analysing microarray-based CGH experiments

open access: yesBMC Bioinformatics, 2004
Background Microarray-based comparative genomic hybridisation (array CGH) is a technique by which variation in relative copy numbers between two genomes can be analysed by competitive hybridisation to DNA microarrays.
