Learning outcomes

1. Knowledge. The student has knowledge about statistical models for spatial and spatio-temporal phenomena, and methods for fitting such models from data. The student has acquired fundamental understanding of inverse problems and regularisation methods for large-scale models. The student has solid understanding of Gaussian process models, hidden Markov models and the ensemble Kalman filter, which are very important tools for extracting insight from spatial and spatio-temporal data. The student also has knowledge about conditioning spatial and spatio-temporal models, and in quantifying the effect of various data gathering schemes for evaluating spatial designs. The student has knowledge about decision theoretic concepts, in particular the value of information, and has acquired solid understanding of spatial decision problems, and the value of information in this context.

2. Skills. The student understands the assumptions underlying important spatio-temporal models, and can use the models and methods to do inference and predictions from spatio-temporal data. The student can use a workflow to conduct value of information analysis in spatial decision situations.

Exam

Oral exam at the end of the semester. Project presentation and questions from curriculum.
