ParaDime: A Framework for Parametric Dimensionality Reduction. [PDF]

Comput Graph Forum, 2023
Abstract ParaDime is a framework for parametric dimensionality reduction (DR). In parametric DR, neural networks are trained to embed high‐dimensional data items in a low‐dimensional space while minimizing an objective function. ParaDime builds on the idea that the objective functions of several modern DR techniques result from transformed inter‐item ...

Gone With the Wind: Exploring a Vanished Rock Dove, <i>Columba livia</i>, Hybrid Zone in the Sahara Desert. [PDF]

Ecol Evol
In this study, we tested the hypothesis of the existence of a hybrid zone between two differentiated rock dove lineages, which may contribute significantly to their divergence. By analyzing newly generated genomic data from previously unsampled African rock dove populations, along with publicly available rock dove genomes, we provide evidence for the ...

Predicting patient-reported quality of vision through multifocal optics. [PDF]

Ophthalmic Physiol Opt
Abstract Purpose To explore the agreement between computationally modelled point‐spread functions (PSFs) and multifocal soft contact lens wearers' descriptions of image quality. Methods In Phase 1, participants were fitted with a single vision soft contact lens (SCL) in the left eye, and four different multifocal (MF) SCLs in the right eye in ...

Perception of political influence within the general population of the United Kingdom

International Social Science Journal, Volume 73, Issue 249, Page 771-787, September 2023., 2023
Abstract When reflecting upon politics, people express judgements about the political influence exerted by different institutions. However, the nature of these judgements remains to be studied by scholars. The paper explores this with a focus on the United Kingdom.

Development of intraindividual value structures in middle childhood: A multicultural and longitudinal investigation

Journal of Personality, Volume 91, Issue 2, Page 482-496, April 2023., 2023
Abstract Objective We examined changes in value interrelations during middle childhood. In line with the Personal Values Theory, we expected a value system, with individuals similarly valuing related motivations, and setting priorities between conflicting motivations.

Localization in wireless sensor networks with gradient descent [PDF]

, 2011
In this article, we present two distance-based sensor network localization algorithms. The location of the sensors is unknown initially and we can estimate the relative locations of sensors by using knowledge of inter-sensor distance measurements ...

Subspace Least Squares Multidimensional Scaling

, 2017
Multidimensional Scaling (MDS) is one of the most popular methods for dimensionality reduction and visualization of high dimensional data. Apart from these tasks, it also found applications in the field of geometry processing for the analysis and ...

A comparison of two techniques for bibliometric mapping: Multidimensional scaling and VOS [PDF]

, 2010
VOS is a new mapping technique that can serve as an alternative to the well-known technique of multidimensional scaling. We present an extensive comparison between the use of multidimensional scaling and the use of VOS for constructing bibliometric maps.
