Uncertainty quantification for electrical impedance tomography using quasi-Monte Carlo methods
Laura Bazahica, Vesa Kaarnioja, Lassi Roininen
The theoretical development of quasi-Monte Carlo (QMC) methods for uncertainty quantification of partial differential equations (PDEs) is typically centered around simplified model…
Log-Gaussian Cox Processes for Spatiotemporal Traffic Fatality Estimation in Addis Ababa
Yassin Tesfaw Abebe, Abdu Mohammed Seid, Lassi Roininen
We investigate the spatiotemporal dynamics of traffic accidents in Addis Ababa, Ethiopia, using 2016--2019 data. We formulate the traffic accident intensity as a log-Gaussian Cox P…
Statistical Batch-Based Bearing Fault Detection
Victoria Jorry, Zina-Sabrina Duma, Tuomas Sihvonen +2
In the domain of rotating machinery, bearings are vulnerable to different mechanical faults, including ball, inner, and outer race faults. Various techniques can be used in conditi…
Bayesian inversion with Student's t priors based on Gaussian scale mixtures
Angelina Senchukova, Felipe Uribe, Lassi Roininen
Many inverse problems focus on recovering a quantity of interest that is a priori known to exhibit either discontinuous or smooth behavior. Within the Bayesian approach to inverse…
