Cascade and parallel combination (CPC) of adaptive filters for estimating heart rate during intensive physical exercise from photoplethysmographic signal

open access: yesHealthcare Technology Letters, 2018
Photoplethysmographic (PPG) signal is getting popularity for monitoring heart rate in wearable devices because of simplicity of construction and low cost of the sensor. The task becomes very difficult due to the presence of various motion artefacts.

Clustering algorithms: A comparative approach

open access: yesPLOS ONE, 2019
De nombreux systèmes du monde réel peuvent être étudiés en termes de tâches de reconnaissance de formes, de sorte qu'une bonne utilisation (et compréhension) des méthodes d'apprentissage automatique dans des applications pratiques devient essentielle. Bien que de nombreuses méthodes de classification aient été proposées, il n'y a pas de consensus sur ...

A visual workspace for constructing hybrid MDS algorithms and coordinating multiple views [PDF]

open access: yes, 2003
Data can be distinguished according to volume, variable types and distribution, and each of these characteristics imposes constraints upon the choice of applicable algorithms for their visualisation.

Solid Primary Retroperitoneal Masses in Adults: An Imaging Approach

open access: yesIndian Journal of Radiology and Imaging, 2022
Mass lesions in the retroperitoneal space may be primary or secondary. Primary retroperitoneal mass lesions are relatively uncommon as compared to pathology that arises secondarily from retroperitoneal organs. These may be solid or cystic lesions.

Algorithmic governance: A modes of governance approach [PDF]

open access: yesRegulation & Governance, 2020
AbstractThis article examines how modes of governance are reconfigured as a result of using algorithms in the governance process. We argue that deploying algorithmic systems creates a shift toward a special form of design‐based governance, with power exercisedex antevia choice architectures defined through protocols, requiring lower levels of ...

Star configuration points and plane curves [PDF]

open access: yes, 2011
2siLet ℓ1,...,ℓ1 be l lines in ℙ2 such that no three lines meet in a point. Let X(l) be the set of points {ℓi ∩ ℓj {divides} 1 ≤ i < j ≤ l} ⊆ ℙ2. We call X(l) a star configuration.

Fairness perceptions of algorithmic decision-making: A systematic review of the empirical literature

open access: yesBig Data & Society, 2022
Algorithmic decision-making increasingly shapes people's daily lives. Given that such autonomous systems can cause severe harm to individuals and social groups, fairness concerns have arisen. A human-centric approach demanded by scholars and policymakers

The splitting method and Poincare's theorem: (II) - matrix, polynomial and language [PDF]

open access: yesComputer Science Journal of Moldova, 2003
This paper is the continuation of the paper which appeared in the previous issue: we revisited Poincare's theorem in the light of the splitting method which was introduced by the author in [5], especially in the geometric aspect of the question. This
