2. 16. Learning from Interactions : Forward and Inverse Decision-Making for Autonomous Dynamical Systems

   Author : Inês de Miranda de Matos Lourenço; Bo Wahlberg; Sandra Hirche; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Intelligent systems; autonomous decision-making; Reinforcement Learning; Markov models; Human-Robot Interaction; Biologically-inspired systems; Electrical Engineering; Elektro- och systemteknik;

   Abstract : Decision-making is the mechanism of using available information to generate solutions to given problems by forming preferences, beliefs, and selecting courses of action amongst several alternatives. In this thesis, we study the mechanisms that generate behavior (the forward problem) and how their characteristics can explain observed behavior (the inverse problem). READ MORE

4. 17. Non-linear dynamic modelling for panel data in the social sciences

   Author : Shyam Ranganathan; David JT Sumpter; Oliver Johnson; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Dynamical systems; stochastic models; Bayesian; panel data; social sciences; development; Mathematics with specialization in Applied Mathematics; Matematik med inriktning mot tillämpad matematik;

   Abstract : Non-linearities and dynamic interactions between state variables are characteristic of complex social systems and processes. In this thesis, we present a new methodology to model these non-linearities and interactions from the large panel datasets available for some of these systems. READ MORE

5. 18. Accelerating Monte Carlo methods for Bayesian inference in dynamical models

   Author : Johan Dahlin; Thomas B. Schön; Fredrik Lindsten; Richard Everitt; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Computational statistics; Monte Carlo; Markov chains; Particle filters; Machine learning; Bayesian optimisation; Approximate Bayesian Computations; Gaussian processes; Particle Metropolis-Hastings; Approximate inference; Pseudo-marginal methods;

   Abstract : Making decisions and predictions from noisy observations are two important and challenging problems in many areas of society. Some examples of applications are recommendation systems for online shopping and streaming services, connecting genes with certain diseases and modelling climate change. READ MORE

6. 19. Aspects of memory and representation in cortical computation

   Author : Martin Rehn; Anders Lansner; Örjan Ekeberg; Peter Földiák; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; cerebral cortex; neural networks; attractor memory; sequence learning; biological vision; generative models; serial order; computational neuroscience; dynamical synapses; Computer science; Datalogi;

   Abstract : Denna avhandling i datalogi föreslår modeller för hur vissa beräkningsmässiga uppgifter kan utföras av hjärnbarken. Utgångspunkten är dels kända fakta om hur en area i hjärnbarken är uppbyggd och fungerar, dels etablerade modellklasser inom beräkningsneurobiologi, såsom attraktorminnen och system för gles kodning.

7. 20. Bayesian learning of structured dynamical systems

   Author : Riccardo Sven Risuleo; Håkan Hjalmarsson; Johan Schoukens; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; system identification; bayesian learning; machine learning; Gaussian processes; Electrical Engineering; Elektro- och systemteknik;

   Abstract : In this thesis, we propose some Bayesian approaches to the identificationof structured dynamical systems. In particular, we consider block-orientedmodels in which a complex system is built starting from simple linear andnonlinear building blocks. READ MORE
