  1. 16. Mathematical modelling in upper secondary school in Sweden : An exploratory investigation

    Författare :Peter Frejd; Christer Bergsten; Jonas Ärlebäck Bergman; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MATHEMATICS; MATEMATIK;

    Sammanfattning : The official curriculum guidelines for upper secondary school in Sweden emphasise the use of mathematical models and mathematical modelling in mathematics education. However, no explicit definitions or descriptions of the notions are given in the curriculum. LÄS MER

  3. 17. Tracking mathematical giftedness in an egalitarian context

    Författare :Linda Mattsson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mathematics; giftedness; creativity; identification; characterization; gifted education; gifted education;

    Sammanfattning : In three different studies upper secondary school head teachers’ characterization and identification of mathematical giftedness was investigated. A survey study (Paper II) explored the conceptions held by 36 randomly selected upper secondary school head teachers in mathematics. LÄS MER

  4. 18. On the optimal stopping time of learning

    Författare :Anna Fedyszak-Koszela; Richard Bonner; Dmitrii Silvestrov; Jacek Malec; Mälardalens högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; stopping time; MATHEMATICS; MATEMATIK;

    Sammanfattning :  The goal of this thesis is to study the economics of computational learning. Attention is also paid to applications of computational learning models, especially Valiant's so-called `probably approximately correctly' (PAC) learning model, in econometric situations. LÄS MER

  5. 19. Considering meteorological variation in assessments of environmental quality trends

    Författare :Claudia Libiseller; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MATHEMATICS; MATEMATIK;

    Sammanfattning : Time series of environmental data are collected to monitor the effectiveness of new emission reduction policies or to determine the general state of the environment. However, small gradual changes in such variables can easily be concealed by large fluctuations caused by prevailing weather conditions. LÄS MER

  7. 20. Reinforcement Learning and Dynamical Systems

    Författare :Björn Lindenberg; Karl-Olof Lindahl; Marc G. Bellemare; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; artificial intelligence; distributional reinforcement learning; Markov decision processes; Bellman operators; deep learning; multi-armed bandits; Bayesian bandits; conjugate priors; Thompson sampling; linear finite dynamical systems; cycle orbits; fixed-point systems; Mathematics; Matematik; Computer Science; Datavetenskap;

    Sammanfattning : This thesis concerns reinforcement learning and dynamical systems in finite discrete problem domains. Artificial intelligence studies through reinforcement learning involves developing models and algorithms for scenarios when there is an agent that is interacting with an environment. LÄS MER
