Is there a Tornado in Alex's Blood Flow? A Case Study for Narrative Medical Visualization
(Journal article; Peer reviewed, 2022)Narrative visualization advantageously combines storytelling with new media formats and techniques, like interactivity, to create improved learning experiences. In medicine, it has the potential to improve patient understanding ... -
IsoTrotter: Visually Guided Empirical Modelling of Atmospheric Convection
(Journal article; Peer reviewed, 2020)Empirical models, fitted to data from observations, are often used in natural sciences to describe physical behaviour and support discoveries. However, with more complex models, the regression of parameters quickly becomes ... -

JASPAR 2014: An extensively expanded and updated open-access database of transcription factor binding profiles
(Peer reviewed; Journal article, 2014-01)JASPAR (http://jaspar.genereg.net) is the largest open-access database of matrix-based nucleotide profiles describing the binding preference of transcription factors from multiple species. The fifth major release greatly ... -

Kernel(s) for Problems with No Kernel: On Out-Trees with Many Leaves
(Peer reviewed; Journal article, 2009)The {\sc \(k\)-Leaf Out-Branching} problem is to find an out-branching, that is a rooted oriented spanning tree, with at least \(k\) leaves in a given digraph. The problem has recently received much attention from the ... -
Kernelization for Spreading Points
(Journal article; Peer reviewed, 2023)We consider the following problem about dispersing points. Given a set of points in the plane, the task is to identify whether by moving a small number of points by small distance, we can obtain an arrangement of points ... -
Kernelization of Graph Hamiltonicity: Proper H-Graphs
(Journal article; Peer reviewed, 2021)We obtain new polynomial kernels and compression algorithms for Path Cover and Cycle Cover, the well-known generalizations of the classical Hamiltonian Path and Hamiltonian Cycle problems. Our choice of parameterization ... -
Kernelization of Vertex Cover by Structural Parameters
(Master thesis, 2015-08-03)In the NP-complete problem Vertex Cover, one is given a graph G and an integer k and are asked whether there exists a vertex set S ⊆ V (G) with size at most k such that every edge of the graph is incident to a vertex in ... -
Kernelization of Whitney Switches
(Journal article; Peer reviewed, 2020)A fundamental theorem of Whitney from 1933 asserts that 2-connected graphs G and H are 2-isomorphic, or equivalently, their cycle matroids are isomorphic, if and only if G can be transformed into H by a series of operations ... -
Kernelization of Whitney Switches
(Journal article; Peer reviewed, 2021)A fundamental theorem of Whitney from 1933 asserts that 2-connected graphs $G$ and $H$ are 2-isomorphic, or equivalently, their cycle matroids are isomorphic if and only if $G$ can be transformed into $H$ by a series of ... -
Kernelizing Temporal Exploration Problems
(Journal article; Peer reviewed, 2023)We study the kernelization of exploration problems on temporal graphs. A temporal graph consists of a finite sequence of snapshot graphs 𝒢 = (G₁, G₂, … , G_L) that share a common vertex set but might have different edge ... -
Kernels of digraphs with finitely many ends
(Journal article; Peer reviewed, 2019)According to Richardson’s theorem, every digraph without directed odd cycles that is either (a) locally finite or (b) rayless has a kernel (an independent subset with an incoming edge from every vertex in ). We generalize ... -
The Lagrangian, constraint qualifications and economics
(Journal article; Peer reviewed, 2022)Considering constrained choice, practitioners and theorists frequently invoke a Lagrangian to generate optimality conditions. Regular use of that vehicle requires, however, some constraint qualification. Yet many economists ... -
Largest chordal and interval subgraphs faster than 2n
(Peer reviewed; Journal article, 2015-08-22)We prove that in a graph with n vertices, induced chordal and interval subgraphs with the maximum number of vertices can be found in time O(2λn) for some λ< 1. These are the first algorithms breaking the trivial 2nnO(1) ... -
Learning Description Logic Ontologies: Five Approaches. Where Do They Stand?
(Journal article; Peer reviewed, 2020)The quest for acquiring a formal representation of the knowledge of a domain of interest has attracted researchers with various backgrounds into a diverse field called ontology learning. We highlight classical machine ... -
Learning from positive and negative examples: New proof for binary alphabets
(Journal article; Peer reviewed, 2024)One of the most fundamental problems in computational learning theory is the problem of learning a finite automaton A consistent with a finite set P of positive examples and with a finite set N of negative examples. By ... -
Learning Horn envelopes via queries from language models
(Journal article; Peer reviewed, 2024)We present an approach for systematically probing a trained neural network to extract a symbolic abstraction of it, represented as a Boolean formula. We formulate this task within Angluin's exact learning framework, where ... -
Learning Possibilistic Logic Theories
(Doctoral thesis, 2023-03-15)Vi tar opp problemet med å lære tolkbare maskinlæringsmodeller fra usikker og manglende informasjon. Vi utvikler først en ny dyplæringsarkitektur, RIDDLE: Rule InDuction with Deep LEarning (regelinduksjon med dyp læring), ...
