  1. 1. Probabilistic Sequence Models with Speech and Language Applications

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Gustav Eje Henter; KTH.; [2013]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Time series; acoustic modelling; speech synthesis; stochastic processes; causal-state splitting reconstruction; robust causal states; pattern discovery; Markov models; HMMs; nonparametric models; Gaussian processes; Gaussian process dynamical models; nonlinear Kalman filters; information theory; minimum entropy rate simplification; kernel density estimation; time-series bootstrap;

    Sammanfattning : Series data, sequences of measured values, are ubiquitous. Whenever observations are made along a path in space or time, a data sequence results. To comprehend nature and shape it to our will, or to make informed decisions based on what we know, we need methods to make sense of such data. LÄS MER

  2. 2. Causal after all a model of mental causation for dualists

    Detta är en avhandling från Umeå : Umeå University

    Författare :Bram Vaassen; Umeå universitet.; [2019]
    Nyckelord :HUMANIORA; HUMANITIES; Mental Causation; Dualism; Non-Reductionism; Causal Exclusion; Causation; Interventionism; Negative Causation; Omissions; Neo-Russellianism; Causation and Physics;

    Sammanfattning : In this dissertation, I develop and defend a model of causation that allows for dualist mental causation in worlds where the physical domain is physically complete.In Part I, I present the dualist ontology that will be assumed throughout the thesis and identify two challenges for models of mental causation within such an ontology: the exclusion worry and the common cause worry.

  3. 3. On the Application of Short-term Causal Models

    Detta är en avhandling från Umeå : Umeå universitet

    Författare :Anders Baudin; Umeå universitet.; [1977]

    Sammanfattning : Causal (econometric) models are often employed as instruments for for-casting in short-term planning within organizations. The aim of this work is to contribute to an understanding of the short-term aspects of causal model building. LÄS MER

  4. 4. Models for Additive and Sufficient Cause Interaction

    Detta är en avhandling från KTH Royal Institute of Technology

    Författare :Daniel Berglund; KTH.; [2019]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Causal Inference; Sufficient Cause; Potential Outcomes; Counterfactual; Additive Interaction; Interaction; MFPO; ICI; Logistic Regression; Linear Odds; Public Health; Interventions; Probabilistic Potential Outcome; Mathematical Statistics; Matematisk statistik;

    Sammanfattning : The aim of this thesis is to develop and explore models in, and related to, the sufficient cause framework, and additive interaction. Additive interaction is closely connected with public health interventions and can be used to make inferences about the sufficient causes in order to find the mechanisms behind an outcome, for instance a disease.

  5. 5. Covariate selection and propensity score specification in causal inference

    Detta är en avhandling från Umeå : Statistik

    Författare :Ingeborg Waernbaum; Umeå universitet.; [2008]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Covariate selection; graphical models; matching; observational studies; treatment effects; unconfoundedness; SOCIAL SCIENCES Statistics; computer and systems science Statistics; SAMHÄLLSVETENSKAP Statistik; data- och systemvetenskap Statistik;

    Sammanfattning : This thesis makes contributions to the statistical research field of causal inference in observational studies. The results obtained are directly applicable in many scientific fields where effects of treatments are investigated and yet controlled experiments are difficult or impossible to implement. LÄS MER
