Current teaching in «real-world» data modelling:

TTK19 - How to discover structures and relations in complex systems? http://www.itk.ntnu.no/emner/fordypning/ttk19
TK8116 - Multivariate Data and Meta Modelling: Preparing for Big Data Cybernetics. http://www.ntnu.edu/studies/courses/TK8116#tab=omEmnet

These data analysis courses are of applied, cognitive and philosophical nature, intended to motivate students for later real-world R&D. Mathematical “soft modelling”, statistical cross-validation and graphical interpretation are combined generically to study Quantitative Big Data with the eyes of physics. Students perform one complete group research project, consisting of problem formulation, experimental design, actual measurements, data preprocessing, one-block multivariate data modelling (PCA) for overview and data clean-up, renewed measurements, two-block multivariate data modelling (PLSR) for overview and quantitative prediction, with cross-validation, graphical model interpretation and final reporting. Data tables from simple series of high-dimensional sound-spectra, or from students’ own projects, are used as a representative of the future’s multichannel measurements.

Current research activities:

Easier use of «never-ending» megavariate data streams, e.g hyperspectral video
New methods for model development in nonlinear dynamics
New ways to reach the creative and the empathic student personality types wrt math and statistics, with a focus on discovery and meaning, rather than proofs and exactness
