Denarié, PierreAntoine (author)Blind Source Separation (BSS), the separation of latent source components from observed mixtures, is relevant to many fields of expertise such as neuroimaging, economics and machine learning. Reliable estimates of the sources can be obtained through diagonalization of the cumulant tensor, i.e., a fourthorder symmetric multilinear array...master thesis 2022

Jonnalagadda, Aravind (author)Natural Language Processing (NLP) deals with understanding and processing human text by any computer software. There are several network architectures in the fields of deep learning and artificial intelligence that are used for NLP. Deep learning techniques like recurrent neural networks and feedforward neural networks are used to develop...master thesis 2022

van Mourik, Ewoud (author)This thesis studies the Canonical Polyadic Decomposition (CPD) constrained kernel machine for large scale learning, i.e. learning with a large number of samples. The kernel machine optimization problem is solved in the primal space, such that the complexity of the problem scales linearly in the number of samples as opposed to scaling cubically...master thesis 2022

LI, Zhehan (author)This thesis applies the GaussNewton optimizer to estimate the parameter values of the VolterraPARAFAC model by minimizing a nonlinear least square cost (NLS) function given the input and output measurements of the MISO Volterra system.master thesis 2022

RöhrigZöllner, Melven (author), Thies, J. (author), Basermann, Achim (author)There are several factorizations of multidimensional tensors into lowerdimensional components, known as ``tensor networks."" We consider the popular ``tensortrain"" (TT) format and ask, How efficiently can we compute a lowrank approximation from a full tensor on current multicore CPUs? Compared to sparse and dense linear algebra, kernel...journal article 2022

Menzen, C.M. (author), Kok, M. (author), Batselier, K. (author)Multiway data often naturally occurs in a tensorial format which can be approximately represented by a lowrank tensor decomposition. This is useful because complexity can be significantly reduced and the treatment of largescale data sets can be facilitated. In this paper, we find a lowrank representation for a given tensor by solving a...journal article 2022

de Rooij, S.J.S. (author)In streaming video completion one aims to fill in missing pixels in streaming video data. This is a problem that naturally arises in the context of surveillance videos. Since these are streaming videos, they must be completed online and in realtime. This makes the streaming video completion problem significantly more difficult than the related...master thesis 2020

Karagöz, Ridvan (author)Bsplines are basis functions for the spline function space and are extensively used in applications requiring function approximation. The generalization of Bsplines to multiple dimensions is done through tensor products of their univariate basis functions. The number of basis functions and weights that define a multivariate Bspline surface,...master thesis 2020

Gedon, Daniel (author)For largescale system with tens of thousands of states and outputs the computation in the conventional Kalman filter becomes timeconsuming such that Kalman filtering in largescale realtime application is practically infeasible. A possible mathematical framework to lift the curse of dimensionality is to lift the problem in higher dimensions...master thesis 2019

Maswan, Jelimo (author)Atrial fibrillation (AF) is one of the more common clinical arrhythmias with a high morbidity and mortality. Despite this, the electrophysiological and pathological mechanisms associated with AF largely remain a mystery, encouraging the use of ever more sophisticated techniques to extract vital information for diagnostic and therapeutic purposes...master thesis 2017

Insuasty, Edwin (author), van den Hof, P.M.J. (author), Weiland, Siep (author), Jansen, J.D. (author)In reservoir engineering, it is attractive to characterize the difference between reservoir models in metrics that relate to the economic performance of the reservoir as well as to the underlying geological structure. In this paper, we develop a dissimilarity measure that is based on reservoir flow patterns under a particular operational...journal article 2017
