Ensembles of Quantifiers
… en la distribución y las propiedades de los ensembles, como es la diversidad, que ayuda a obtener mejores meta-modelos. La diversidad se puede introducir generando una muestra de entrenamiento distinta para cada modelo. Este punto conecta la cuantificación con los ensembles. Siguiendo esa …

Beta-ensembles with covariance
… for the [beta]-Wishart and [beta]-MANOVA ensembles with diagonal covariance. These generalize the [beta]-ensembles of Dumitriu-Edelman, Lippert, Killip-Nenciu, Forrester-Rains, and Edelman-Sutton, as well as the classical [beta] = 1, 2,4 ensembles of James, Li-Xue, and Constantine. …

Optimal Control of Inhomogeneous Ensembles
This dissertation is concerned with formulating the problem and developing methods for the synthesis of optimal, open-loop inputs for large numbers of identically structured dynamical systems that exhibit variation in the values of characteristic parameters across the collection, or ensemble. Our …

Approaches to ensembles of universes
… them focusing on different aspects relating to ensembles of universes and causally disconnected regions. In the first part I investigate possible measures over the space of FLRW models. In the second part I examine the behaviour of such transition regions for spherically symmetric space-times. …

Eigenvalue statistics for beta-ensembles
… originating in physics (the "Gaussian" ensembles) and the Laguerre distributions of statistics (the "Wishart" matrices). One of our main contributions is the construction of tridiagonal matrix models for the general (β > 0) 0 β-Hermite and (β > 0, a > β(m - 1)/2) β-Laguerre ensembles of …

Unstable Communities in Network Ensembles
Ensembles of graphs arise naturally in many applications, for example, the temporal evolution of social contacts or computer communications, tissue-specific protein interaction networks, annual citation or co-authorship networks in a field, or a family of high-likelihood Bayesian networks inferred …

Synchronization in ensembles of nonisochronous oscillators
… Synchronisationsphaenomene, die in grossen Ensembles von interagierenden Oszillatoren auftauchen. Im speziellen werden die Effekte von Nicht-Isochronizitaet (die Abhaengigkeit der Frequenz von der Amplitude des Oszillators) auf den makroskopischen Uebergang zur Synchronisation im Detail …

Using Ensembles for Web Effort Estimation
… estimation techniques can be combined to create ensembles that consistently performed well when used for general software effort estimation. This motivated us to replicate this study using Web project data from the Tukutuku dataset. Our results confirmed that such ensembles are also effective in …

Fast human detection with cascaded ensembles
Detecting people in images is a challenging task because of the variability in clothing and illumination conditions, and the wide range of poses that people can adopt. To discriminate the human shape clearly, Dalal and Triggs [1] proposed a gradient based, robust feature set that yielded excellent …

Pitman estimation for ensembles and mixtures
… (MRE) estimation of a location scalar μ in ensembles and mixtures of translation families having structured dispersion matrices Σ. The principal focus is the preservation of Pitman's solutions across classes of distributions. To these ends the cone S<sub>n</sub>⁺ of positive definite …

Time Series classification through transformation and ensembles
… on variable intervals and creating tree-based ensembles with summary measures. We wish to answer a specific research question: given a new TSC problem without any prior, specialised knowledge, what is the best way to approach the problem? Our thesis is that the best methodology is to first …

Cellular Ensembles in Alveolar Homeostasis and Repair
<p>Lung epithelium, the lining that covers the inner surface of the respiratory tract, is directly exposed to the environment and thus susceptible to airborne toxins, irritants, and pathogen-induced damages. In adult mammalian lungs, epithelial cells are generally quiescent but can respond rapidly …

Light scattering: from ensembles to single particles
Light scattering enables the interrogation of nanoscale systems with minimal perturbation to their dynamics. However, this advantage of optical techniques is partially offset by requiring complex inference procedures to accurately estimate physical quantities of interest from features extracted by …

Transport methods and universality for [beta]-ensembles
… global properties of the eigenvalues of [beta]-ensembles. A lot of attention has been drawn recently on the universal properties of [beta]-ensembles, and how their local statistics relate to those of Gaussian ensembles. We use transport methods to prove universality of the eigenvalue gaps in the …

Quantum nonlinear optics using cold atomic ensembles
… be mediated by matter, in our case cold atomic ensembles, which provide a nonlinear medium. In conventional nonlinear media, the nonlinearities are negligibly weak at intensities corresponding to single photons and nonlinear optics at the few-photon level is a long-standing goal of optical and …

Contributions to Ensembles of Models for Predictive Toxicology Applications. On the Representation, Comparison and Combination of Models in Ensembles.
… this thesis, contributions are proposed towards ensembles of models with a focus on model representation, comparison and usage. Predictive Toxicology was chosen as an application field to demonstrate the proposed approach to represent predictive models linked to data for DMG. Further analysing …

Female Ensembles: Lesbian Neo-Victorian Fiction, 1998-2023
Female Ensembles is a study of lesbian historical fiction set in the nineteenth century. This project takes a reparative approach as Eve Sedgwick defines it (1997) to lesbian literary history through neo-Victorian novels, short fiction, and film from the last twenty-five years. Chapter one argues …
