Constructive Layer-Wise Conversion of a Tensor Train into a MERA
In this article, two new algorithms are presented that convert a given data tensor train into either a Tucker decomposition with orthogonal matrix factors or a multi-scale entanglement renormalization ansatz (MERA). The Tucker core tensor is never explicitly computed but stored a

Low-Rank Tensor Decompositions for Nonlinear System Identification
A Tutorial with Examples
Nonlinear parametric system identification is the estimation of nonlinear models of dynamical systems from measured data. Nonlinear models are parameterized, and it is exactly these parameters that must be estimated. Extending familiar linear models to their nonlinear counterpart

Robotic swarm control through artificial pheromone trails
The case of curious ants
The extraordinary capability of swarming ant species in route finding and foraging efficiency through trail trail development has been studied for many years. Scientists have been able to capture the behavior of individual ants in control algorithms and used the resulting artific

Tensor decomposition for Independent Component Analysis
Through implicit cumulant tensor manipulation
Blind Source Separation (BSS), the separation of latent source components from observed mixtures, is relevant to many fields of expertise such as neuro-imaging, economics and machine learning. Reliable estimates of the sources can be obtained through diagonalization of the cumula

Adaptive Observer for Automated Emergency Maneuvers
Fusing cost-efficient onboard sensors with computer vision into a robust estimate of sideslip angle using online covariance calculation
One of the most promising ideas in autonomous vehicle control systems is letting the vehicle drive autonomously outside the normal, linear, operating region and letting it "drift". By doing so, the maneuverability of the vehicle could be enhanced. To enable systems that can contr

All-at-once optimization for kernel machines with canonical polyadic decompositions
Enabling large scale learning for kernel machines
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

Collision Avoidance in Surface Mines
A centralized approach
Due to new legislation, a lot of research is done in the development of a Collision Avoidance Systems (CAS) for surface mines. Almost all CASs studied in literature are decentralized and developed for passenger vehicles or aviation applications. That makes them unsuitable for the

Tensor Network Kalman Filter for Large-Scale MIMO Systems
With Application to Adaptive Optics
For large-scale system with tens of thousands of states and outputs the computation in the conventional Kalman filter becomes time-consuming such that Kalman filtering in large-scale real-time application is practically infeasible. A possible mathematical framework to lift the cu

Optimal Control of Autonomous Greenhouses
A Data-Driven Approach
The world population is growing rapidly and the demand for healthy food grows with it. Greenhouse cultivation provides an efficient way to grow crops in a protected and controlled environment. In the past, many greenhouse control algorithms have been developed. How- ever, the ma

Uncertainty quantification for tensor network constrained kernel machines
A frequentist and Bayesian approach
This research aims at quantifying the uncertainty in the predictions of tensor network constrained kernel machines, focusing on the Canonical Polyadic Decomposition (CPD) constrained kernel machine. Constraining the parameters in the kernel machine optimization problem to be a CP

Sparse reconstruction for High Dimensional Tensors
Low complexity methods for large scale sensing
Compressed sensing is a framework in signal processing that enables the efficient acquisition and reconstruction of sparse signals. A widely-used class of algorithms that are used for this reconstruction, called greedy-algorithms, depend on non-convex optimization. With increasin

Epileptic seizure classification using scalp EEG data
A support tensor machine approach
Algorithms which can effectively detect epileptic seizures have the potential to improve current treatment methods for people who suffer from epilepsy. The current state-of-the-art methods use neural networks, which are able to learn directly from the electroencephalogram (EEG) d

Canonical Polyadic Decomposition in Autoencoders for ECG Analysis
Exploring the effect of the CPD in unsupervised transfer learning methods for cardiac arrhythmia detection
This thesis studies the application of the Canonical Polyadic Decomposition (CPD) in unsupervised transfer learning methods for cardiac arrhythmia detection. Unsupervised learning methods have become more prevalent in the healthcare sector due to the abundance of unlabeled data.

Traditionally, Event-Triggered Control (ETC) methods are sample-and-hold control schemes that implement a triggering condition in order to reduce the number of control updates. Given a decay rate of the Lyapunov function, they focus on minimizing the (average) Inter-Sample Time (
