(Master thesis / Masteroppgave, 2019)Recovering signals from undersampled measurements is a well-studied topic in mathematics. During the last decade, many attempts have been made to solve this problem using machine learning, with resulting reconstruction ...
-
(Master thesis / Masteroppgave, 2013)The purpose of this thesis is to perform some mathematical analysis and study numerical solutions of different models describing (different aspects of) axonal transport. We will explain our numerical results using mathematical ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2020)The tetrachoric correlation is a popular measure of association for binary data and estimates the correlation of an underlying normal latent vector. However, when the underlying vector is not normal, the tetrachoric ...
-
(Research report / Forskningsrapport, 2006)We study a stochastic control problem where the state process is described by a stochastic differential equation driven by a Brownian motion and a Poisson random measure, being affine in both the state and the control. The ...
-
(Master thesis / Masteroppgave, 2022)In this thesis we wish to explore and develop Solvency II-compliant computational tools that will provide arguments for the insurance company to employ internal models. Applying these tools we will replace some of the ...

(Research report / Forskningsrapport, 2006)There exist many methods for survival prediction from high-dimensional genomic data. Most of them combine the Cox proportional hazards model with some dimension reduction estimation technique, like partial least squares ...
-
(Report / Rapport / SubmittedVersion, 2018)For large multicomponent systems it is typically too costly to monitor the entire system constantly. In the present paper we consider a case where a component is unobserved in a time interval [0, T]. Here T is a stochastic ...

(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2012)The single auction equilibrium of Kyle’s (1985) is studied, in which noise traders may be partially informed, or alternatively they can be manipulated. Unlike Kyle’s assumption that the quantity traded by the noise traders ...
-
(Journal article / Tidsskriftartikkel / SubmittedVersion, 2020)In many statistical regression and prediction problems, it is reasonable to assume monotone relationships between certain predictor variables and the outcome. Genomic effects on phenotypes are, for instance, often assumed ...

-
(Research report / Forskningsrapport, 2013)Sequential Monte Carlo (SMC) methods are one of the most important computational tool to deal with intractability in complex statistical models. In those techniques, the distribution of interest is approximated by a set ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)We introduce a weighted particle representation for the solution of the filtering problem based on a suitably chosen variation of the classical de Finetti theorem. This representation has important theoretical and numerical ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)In a previous work, we gave a construction of (not necessarily realisable) oriented matroids from a triangulation of a product of two simplices. In this follow-up paper, we use a combinatorial analogue of Viro's patchworking ...
