  1. 1. Bayesian structure learning in graphical models

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Felix Leopoldo Rios; KTH.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bayesian statistics; graphical models; Bayesian networks; Markov networks; structure learning; Tillämpad matematik och beräkningsmatematik; Applied and Computational Mathematics;

    Abstract : This thesis consists of two papers studying structure learning in probabilistic graphical models for both undirected graphs anddirected acyclic graphs (DAGs).Paper A, presents a novel family of graph theoretical algorithms, called the junction tree expanders, that incrementally construct junction trees for decomposable graphs.

  2. 2. Bayesian learning of structured dynamical systems

    University dissertation from KTH Royal Institute of Technology

    Author : Riccardo Sven Risuleo; KTH.; [2018]
    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

  3. 3. Option Pricing and Bayesian Learning

    University dissertation from Department of Economics, Lund Universtiy

    Author : Ola Jönsson; Lunds universitet.; Lund University.; [2007]
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; ekonomisk politik; ekonomiska system; ekonomisk teori; ekonometri; Bayesian learning; Volatility smile; Economics; Polya urn model; economic theory; econometrics; economic systems; Nationalekonomi; economic policy; Finansiering; Financial science;

    Abstract : Popular Abstract in Swedish En europeisk köpoption ger innehavaren rätten, men inte skyldigheten, att köpa en underliggande tillgång till ett visst pris, lösenpriset, vid ett bestämt datum, lösendagen. En europeisk säljoption definieras på motsvarande sätt: den ger innehavaren rätten, men inte skyldigheten att sälja den underliggande tillgången. READ MORE

  4. 4. Spike-Based Bayesian-Hebbian Learning in Cortical and Subcortical Microcircuits

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Philip Tully; KTH.; [2017]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bayes rule; synaptic plasticity and memory modeling; intrinsic excitability; naïve Bayes classifier; spiking neural networks; Hebbian learning; neuromorphic engineering; reinforcement learning; temporal sequence learning; attractor network; Datalogi; Computer Science;

    Abstract : Cortical and subcortical microcircuits are continuously modified throughout life. Despite ongoing changes these networks stubbornly maintain their functions, which persist although destabilizing synaptic and nonsynaptic mechanisms should ostensibly propel them towards runaway excitation or quiescence.

  5. 5. Models of Cooperation, Learning and Catastrophic Risk

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Vilhelm Verendel; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Backward Induction; Bayesian analysis; Finitely Repeated Prisoners Dilemma; Cooperation; Fermi Paradox; Learning; Climate negotiations; Catastrophic risk;

    Abstract : Our world presents us with dangers and opportunities. Some of these dangers and opportunities are easier to handle if two or more individuals learn to cooperate. This thesis contributes five papers about cooperation, learning and catastrophic risk. READ MORE
