1. 11. User Modeling for Adaptive Virtual Reality Experiences : Personalization from Behavioral and Physiological Time Series

   Författare :Luis Quintero; Uno Fors; Lijffijt Jefrey; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; virtual reality; VR; machine learning; ML; user modeling; personalization; wearable; heart rate; HRV; biosensors; movement; behavioral; user experience; UX; spatial computing; metaverse; extended reality; XR; data- och systemvetenskap; Computer and Systems Sciences;

   Sammanfattning : Research in human-computer interaction (HCI) has focused on designing technological systems that serve a beneficial purpose, offer intuitive interfaces, and adapt to a person's expectations, goals, and abilities. Nearly all digital services available in our daily lives have personalization capabilities, mainly due to the ubiquity of mobile devices and the progress that has been made in machine learning (ML) algorithms.

3. 12. Goodness-of-fit in Multivariate Time Series

   Författare :Huong Nguyen Thu; Campus de Getafe Facultad de Ciencias Sociales y Jurıdicas Department of Statistics Universidad Carlos III de Madrid; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Economics; Nationalekonomi;

   Sammanfattning : Goodness-of-fit is an important task in time series analysis. In this thesis, wepropose a new family of statistics and a new goodness-of-fit process for the wellknownmultivariate autoregressive moving average VARMA(p,q) model.Some preliminary results are studied first for an initial goodness-of-fit method.

4. 13. Asymmetry and multiscale dynamics in macroeconomic time series analysis

   Författare :Olivier Habimana; Pär Sjölander; Kristofer Månsson; Guglielmo Maria Caporale; Jönköping University; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : This thesis consists of three independent articles preceded by an introductory chapter. The first two articles focus on exchange rate dynamics in emerging market and developing economies, taking into account nonlinearities and asymmetries which are relevant for these countries and are potentially due to (i) transaction costs and other market frictions, and (ii) official intervention in the foreign exchange market.

7. 15. Gaze Based Human Intention Analysis

   Författare :Julius Pettersson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; eye tracking; psychological testing; Virtual reality VR ; deep machine learning; human intention prediction; collaborative robots; uncertainty estimation; time series analysis;

   Sammanfattning : The ability to determine an upcoming action or what decision a human is about to take, can be useful in multiple areas, for example during human-robot collaboration in manufacturing, where knowing the intent of the operator could provide the robot with important information to help it navigate more safely. Another field that could benefit from a system that provides information regarding human intentions is the field of psychological testing where such a system could be used as a platform for new research or be one way to provide information in the diagnostic process.
