Mining time series is a machine learning subfield that focuses on a particular data structure, where variables are measured over (short or long) periods of time.

In this thesis, "culture" refers to the collection of subjective human traits, such as preferences an opinions, that a given, geographically bounded population has at a given moment in time.

The research programme Statistical Science is concerned with the analysis and interpretation of masses of data, the quantification of uncertainty using probability models, and the development and benchmarking of algorithms and methods with these aims.

The programme group Research Methods and Statistics has a broad orientation on research. It offers support to researchers from a variety of research projects within Education and Child Studies.

The objective of this project is the development of a new psychometric model, called the Generalized Squared Distance Logistic Model (GSDLM). This model is an evolution of older psychometric approaches (such as PARELLA, GHCM, and GGUM) and the Gaussian Ordination Models (GOMs) used in environmental…

Does the δ-machine have higher accuracy than the other feature-based classifiers in some conditions?

A project to explore the configuration of different types of settlement and its role in the evolution of landscape, both in pre-Roman times and in the so-called Colonial landscape. We used several techniques of field survey, pottery classification and other non-invasive approaches to the archaeological…

Can metabolomic profiling be used to predict resistance against insect herbivores in plants?

Climate change is a challenge for both current and future generations. New biological resources have to be developed in order to meet the demand for energy as well as the demand for food.

Dementia is a progressive disease, diagnosed at a relatively late stage when intervention may not be effective. Aim of the research is to study scans of brain networks to help discover the early network changes related to dementia. Early diagnosis may benefit effectiveness of future treatment.

The lack of success of new CNS drugs in clinical development is in part due to the complexity of the CNS, unexpected side effects, difficulties for drugs to penetrate the brain, but also by the lack of biomarkers.

Which metabolites of sponge are influenced by individual environmental or biological factors?

University-school partnerships are important constellations for teachers’ professional learning. The present study investigates how both teacher characteristics and contextual factors are related to teachers’ motivation to participate in the university-school partnership, and the relationship between…
