1. Classification models for high-dimensional data with sparsity patterns
Sammanfattning : Today's high-throughput data collection devices, e.g. spectrometers and gene chips, create information in abundance. However, this poses serious statistical challenges, as the number of features is usually much larger than the number of observed units. LÄS MER
2. Feature Informativeness, Curse-of-Dimensionality and Error Probability in Discriminant Analysis
Sammanfattning : This thesis is based on four papers on high-dimensional discriminant analysis. Throughout, the curse-of-dimensionality effect on the precision of the discrimination performance is emphasized. A growing dimension asymptotic approach is used for assessing this effect and the limiting error probability are taken as the performance criteria. LÄS MER
3. Big Data Analytics for eMaintenance : Modeling of high-dimensional data streams
Sammanfattning : Big Data analytics has attracted intense interest from both academia and industry recently for its attempt to extract information, knowledge and wisdom from Big Data. In industry, with the development of sensor technology and Information & Communication Technologies (ICT), reams of high-dimensional data streams are being collected and curated by enterprises to support their decision-making.

4. Big Data Analytics for Fault Detection and its Application in Maintenance
Sammanfattning : Big Data analytics has attracted intense interest recently for its attempt to extract information, knowledge and wisdom from Big Data. In industry, with the development of sensor technology and Information & Communication Technologies (ICT), reams of high-dimensional, streaming, and nonlinear data are being collected and curated to support decision-making.

5. Six-dimensional theories with (2,0) supersymmetry
Sammanfattning : In this thesis the so called (2,0) theories in six dimensions are discussed. These theories are of special interest because they do not contain dynamical gravity despite their high dimensionality. LÄS MER
