Inference of Spatio-Temporal Functions over Graphs via Multi-Kernel Kriged Kalman Filtering
Vassilis N. Ioannidis, Daniel Romero, Georgios B. Giannakis
Inference of space-time varying signals on graphs emerges naturally in a plethora of network science related applications. A frequently encountered challenge pertains to reconstruc…
New applications of extremely regular function spaces
Trond A. Abrahamsen, Olav Nygaard, Märt Põldvere
Let be an infinite locally compact Hausdorff topological space. We show that extremely regular subspaces of have very strong diameter properties and, for every rea…
Kernel-based Inference of Functions over Graphs
Vassilis N. Ioannidis, Meng Ma, Athanasios N. Nikolakopoulos +2
The study of networks has witnessed an explosive growth over the past decades with several ground-breaking methods introduced. A particularly interesting -- and prevalent in severa…
On the timing between terrestrial gamma ray flashes, radio atmospherics, and optical lightning emission
Thomas Gjesteland, Nikolai Østgaard, Phillip Bitzer +1
On 25 October 2012 the Reuven Ramaty High Energy Solar Spectroscope Imager (RHESSI) and the Tropical Rainfall Measuring Mission (TRMM) satellites passed over a thunderstorm on the…
Bayesian Unification of Gradient and Bandit-based Learning for Accelerated Global Optimisation
Ole-Christoffer Granmo
Bandit based optimisation has a remarkable advantage over gradient based approaches due to their global perspective, which eliminates the danger of getting stuck at local optima. H…
Strongly extreme points and approximation properties
Trond A. Abrahamsen, Petr Hájek, Olav Nygaard +1
We show that if is a strongly extreme point of a bounded closed convex subset of a Banach space and the identity has a geometrically and topologically good enough local approxi…
Exploratory and Confirmatory Factor Analyses of Religiosity. A Four-Factor Conceptual Model
Carlos Miguel Lemos, Ross Gore, F. LeRon Shults
We describe an exploratory and confirmatory factor analysis of the International Social Survey Programme Religion Cumulation (1991-1998-2008) data set, to identify the factors of i…
Relatively weakly open convex combinations of slices
Trond A. Abrahamsen, Vegard Lima
We show that , and in fact for any scattered compact Hausdorff space , have the property that finite convex combinations of slices of the unit ball are relatively we…
