  1. 1. Machine Learning Survival Models : Performance and Explainability

    Author : Abdallah Alabdallah; Mattias Ohlsson; Thorsteinn Rögnvaldsson; Sepideh Pashami; Erik Frisk; Högskolan i Halmstad; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Survival Analysis; Explainable Artificial Intelligence; Survival Patterns; Counterfactual Explanations; Evaluation Metrics; Concordance Index;

    Abstract : Survival analysis is an essential statistics and machine learning field in various critical applications like medical research and predictive maintenance. In these domains understanding models' predictions is paramount. READ MORE

  2. 2. Learning local predictive accuracy for expert evaluation and forecast combination

    Author : Oscar Oelrich; Mattias Villani; Francesco Ravazzolo; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bayesian; forecast combination; predictive density; Gaussian process; bootstrap; Bayes factors; model selection; Bayesian predictive synthesis; nonparametric methods; power transformation; expected log predictive density; variable selection; statistik; Statistics;

    Abstract : This thesis consists of four papers that study several topics related to expert evaluation and aggregation. Paper I explores the properties of Bayes factors. Bayes factors, which are used for Bayesian hypothesis testing as well as to aggregate models using Bayesian model averaging, are sometimes observed to behave erratically. READ MORE

  3. 3. Predictive control for autonomous driving : With experimental evaluation on a heavy-duty construction truck

    Author : Pedro Lima; Bo Wahlberg; Jonas Mårtensson; Alberto Bemporad; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Autonomous vehicles; model predictive control; automatic control; heavy-duty vehicles; mining; trucks; clothoids; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Autonomous vehicles is a rapidly expanding field, and promise to play an important role in society. In more isolated environments, vehicle automation can bring significant efficiency and production benefits and it eliminates repetitive jobs that can lead to inattention and accidents. READ MORE

  4. 4. Linear Model Predictive Control : Stability and Robustness

    Author : Johan Löfberg; Lennart Ljung; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Most real systems are subjected to constraints, both on the available control effort and the controlled variables. Classical linear feedback is in some cases not enough for such systems. This has motivated the development of a more complicated, nonlinear controller, called model predictive control, MPC.

  5. 5. Predictive eyes precede retrieval : visual recognition as hypothesis testing

    Author : Linus Holm; Timo Mäntylä; Lars Nyberg; David Melcher; Umeå universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; declarative memory; face perception; object recognition; scene recognition; eye movements; visual awareness; recollection; familiarity; Psychology; Psykologi;

    Abstract : Does visual recognition entail verifying an idea about what is perceived? This question was addressed in the three studies of this thesis. The main hypothesis underlying the investigation was that visual recognition is an active process involving hypothesis testing. READ MORE
