Performance and Interpretability of Entity Matching with Deep Learning
(Doctoral theses at NTNU;2024:173, Doctoral thesis, 2024)Entity matching is the problem of identifying which records refer to the same real-world entity. It is a key data integration task and, despite decades of research, is still challenging. In recent years, deep learning has ... -
Performance evaluation of no-reference image quality metrics for face biometric images
(Journal article; Peer reviewed, 2018)The accuracy of face recognition systems is significantly affected by the quality of face sample images. The recent established standardization proposed several important aspects for the assessment of face sample quality. ... -
Performance Evaluation of No-Reference Image Quality Metrics for Visible Wavelength Iris Biometric Images
(Chapter, 2018)Image quality assessment plays an important role in iris recognition systems because the system performance is affected by low quality iris images. With the development of electronic color imaging, there are more and more ... -
Performance impact of porous media characteristics for lattice Boltzmann method
(Master thesis, 2020)Ettersom regnekraft er en begrenset ressurts er det et vedvarende behov for å forbedre ytelsen til både nye og eksisterende programmer. I denne oppgaven benytter vi metoder fra ytelsesmodellering og en stedfortreder-applikasjon ... -
Performance Modeling of a Finite Volume Method for the Shallow Water Equations
(Master thesis, 2022)Oppgaven omhandler en proxy-applikasjon for å beregne grunnvannsligningene gjennom den endelige volummetoden. Vannoverflaten er diskretisert gjennom en triangulering, der kystlinjen til Mehamn brukes til alle tester. ... -
Performance Modeling of a Load-Balanced FDM Wave Equation Solver on Heterogeneous Clusters
(Master thesis, 2023)I denne avhandlingen utvikles en skalerbar implementasjon av endelig differansemetode for å løse den todimensjonale bølgelikningen. Vi utvikler algoritmer som benytter lastbalansering i flere lag for å sikre at ... -
Performance Modeling of Adaptive Mesh Refinement for the Shallow Water Equations
(Master thesis, 2020)I denne avhandlinga studerer me ytings- og skalerings-karakteristikkar ved adaptivt raffinerte endelege differansar-løysingar av gruntvasslikningane. Gruntvasslikningane er eit sett med likningar som blir nytta til å ... -
Performance modeling of CFD application scalability using co-design methods
(Master thesis, 2018)In this thesis, we investigate the performance and scalability of two CFD proxy applications, based on the Lattice Boltzmann Method (LBM) and Smoothed Particle Hydrodynamics (SPH). Two variants of LBM, workshare and task, ... -
Performance Modeling of Finite Difference Shallow Water Equation Solvers with Variable Domain Geometry
(Master thesis, 2021)I denne oppgaven undersøker vi metoder som kan brukes til å redusere ubalansert beregningslast, som kan oppstå når man dekomponerer et todimensjonalt domene av endelige differanser med ujevn beregningskostnad. I dette ... -
Performance Modeling of Heterogeneous Systems
(Doktoravhandlinger ved NTNU, 1503-8181; 2012:344, Doctoral thesis, 2012)As the complexity of parallel computers grows, constraints posed by the construction of larger systems require both greater, and increasingly non-linear, parameter sets to model their behavior realistically. These heterogeneous ... -
Performance modeling of subdomain discretization techniques for SPH proxy applications
(Master thesis, 2021)In this study we investigate the performance of two cell-grid discretization schemes for a smoothed-particle hydrodynamics (SPH) proxy application that is applied to the two-dimensional dam-break problem. The Cell+Table ... -
Performance of machine learning models in estimation of ground reaction forces during balance exergaming
(Peer reviewed; Journal article, 2022)Background Balance training exercise games (exergames) are a promising tool for reducing fall risk in elderly. Exergames can be used for in-home guided exercise, which greatly increases availability and facilitates ... -
