(Research report / Forskningsrapport, 2001)We give a short introduction to some of the theory and methods involved in stochastic control with partial observation. As an illustration we use the stochastic maximum principle and the Kalman-Bucy filter to solve explicitly ...

(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2017)We show that the Cuntz splice induces stably isomorphic graph C∗-algebras. This result is a key step towards the recent complete classification of unital graph C∗-algebras both with respect to K-theoretical classification ...

(Master thesis / Masteroppgave, 2017)The estimation of inverse covariance matrices plays a major role in portfolio optimization, for the global minimum variance portfolio in mean-variance analysis it is the only parameter used to determine the asset allocation. ...

(Doctoral thesis / Doktoravhandling, 2023)Most forms of dementia, including Alzheimer’s, are incurable and their causes are not properly understood. In recent years, it has been suggested that the cerebrospinal fluid, a water-like fluid that surrounds the brain, ...

(Master thesis / Masteroppgave, 2021)While neural networks have been demonstrated to be highly successful in mathematical and statistical modelling of a comprehensive selection of problems, their application to inverse problems is not without complications. ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)We study the reciprocal variety to the LSSM of catalecticant matrices associated with ternary quartics. With numerical tools, we obtain 85 to be its degree and 36 to be the ML-degree of the LSSM. We provide a geometric ...

Investigating molecular transport in the human brain from MRI with physics-informed neural networks (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Abstract In recent years, a plethora of methods combining neural networks and partial differential equations have been developed. A widely known example are physics-informed neural networks, which solve problems involving ...
