On the effect of positional encodings in Transformer models for time series forecasting
(Master thesis, 2021)Denne oppgaven undersøker effekten posisjons-koding (positional encoding) har på prediksjon av tidsrekker med Transformer modeller. Prediksjon av tidsrekker er et viktig problem med mange bruksområder. Nøyaktige prediksjoner ... -
On the feasability of automatic segmentation with active contour models in image databases for shape extraction
(Master thesis, 2005)In this thesis the image segmentation system EDISON, was tested against an automatic version snake, which is an algorithm active contour models. The algorithms were tested against each to see if an automatic snake algorithm ... -
On the improvement of 2D quality assessment metrics for omnidirectional images
(Peer reviewed; Journal article, 2020)Subjective quality assessment remains the most reliable way to evaluate image quality while being tedious and money consuming. Therefore, objective quality evaluation ensures a trade-off by providing a computational approach ... -
On the Nature of Perceptual Translucency
(Journal article, 2020)Translucency is an appearance attribute used to characterize materials with some degree of subsurface light transport. Although translucency as a radiative transfer inside the medium is relatively well understood, translucency ... -
On the Quantification of Visual Texture Complexity
(Peer reviewed; Journal article, 2022)Complexity is one of the major attributes of the visual perception of texture. However, very little is known about how humans visually interpret texture complexity. A psychophysical experiment was conducted to visually ... -
On the Relation Between ROC and CMC
(Journal article; Peer reviewed, 2023)We formulate a compact relation between the probabilistic Receiver Operating Characteristic (ROC) and the probabilistic Cumulative Match Characteristic (CMC) that predicts every entry of the probabilistic CMC as a functional ... -
On the Social Shaping Dimensions of Smart Sustainable Cities: A Study in Science, Technology, and Society
(Journal article; Peer reviewed, 2017)Situated within science of science, this study analyzes the nature, practice, and impact of ICT of the new wave of computing for urban sustainability as a form of science and technology (S&T) within the defining context ... -
On the Sustainability of Smart and Smarter Cities in the Era of Big Data: An Interdisciplinary and Transdisciplinary Literature Review
(Journal article; Peer reviewed, 2019)There has recently been a conscious push for cities across the globe to be smart and even smarter and thus more sustainable by developing and implementing big data technologies and their applications across various urban ... -
On the Usage of Metaheuristic Optimization in Cryptanalysis
(Master thesis, 2021)Denne oppgaven utforsker muligheten for å løse kryptografiske dekrypsjonsproblemer med optimaliseringsalgoritmer, ved å gjøre krypteringstekst til løsbare optimaliseringsproblemer, og deretter løse dem med et C++ rammeverk. -
On the Use of a Convolutional Neural Network to Predict Perceptual Quality of Images without Reference for Different Viewing Distances
(Chapter, 2019)A plethora of image quality metrics have been proposed in the literature. These metrics aims to estimate the perceptual image quality automatically. One important key aspect that the perceived quality is dependent on is ... -
On the Use of Air Quality Microsensors for Supporting Decision Makers
(Chapter, 2020)In this poster we present how a network of Internet-of-things (IoT) devices facilitated through machine learning can improve decision making. Our application domain is air quality in the municipality of Trondheim. Ambient ... -
On those ordinary differential equations that are solved exactly by the improved Euler method
(Journal article; Peer reviewed, 2013)As a numerical method for solving ordinary differential equations y'=f(x,y), the improved Euler method is not assumed to give exact solutions. In this paper we classify all cases where this method gives the exact solution ... -
On Traczyk’s BCK-sequences
(Peer reviewed; Journal article, 2022)BCK-sequences and n-commutative BCK-algebras were introduced by T. Traczyk, together with two related problems. The first one, whether BCK-sequences are always prolongable. The second one, if the class of all n-commutative ... -
On Validation and Predictability of Digital Badges’ Influence on Individual Users
(Journal article; Peer reviewed, 2018)Badges are a common, and sometimes the only, method of incentivizing users to perform certain actions on online sites. However, due to many competing factors influencing user temporal dynamics, it is difficult to determine ... -
