  1. 1. Intelligent Driver Mental State Monitoring System Using Physiological Sensor Signals

    Författare :Shaibal Barua; Peter Funk; Shahina Begum; Mobyen Uddin Ahmed; Christer Ahlström; Jose Peña; Mälardalens högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Artificial Intelligent; Intelligent systems; Physiological signal; Driver monitoring; Computer Science; datavetenskap;

    Sammanfattning : Driving a vehicle involves a series of events, which are related to and evolve with the mental state (such as sleepiness, mental load, and stress) of the driv- er. These states are also identified as causal factors of critical situations that can lead to road accidents and vehicle crashes. LÄS MER

  3. 2. Gated Bayesian Networks

    Författare :Marcus Bendtsen; Jose M. Peña; Nahid Shahmehri; Helge Langseth; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Bayesian networks have grown to become a dominant type of model within the domain of probabilistic graphical models. Not only do they empower users with a graphical means for describing the relationships among random variables, but they also allow for (potentially) fewer parameters to estimate, and enable more efficient inference.

  4. 3. Studying earnings trajectories as functional outcomes

    Författare :Kreske Ecker; Xavier de Luna; Lina Schelin; Jose Peña; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; functional data analysis; causal inference; earnings trajectories; simultaneous confidence bands; missing data; Statistics; statistik;

    Sammanfattning : In this thesis, we present methods for studying patterns of income accumulation over time using functional data analysis. This is made possible by the availability of large-scale longitudinal register data in Sweden. LÄS MER

  5. 4. A Study of Chain Graph Interpretations

    Författare :Dag Sonntag; Jose M. Peña; Nahid Shahmehri; Jirka Vomlel; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Probabilistic graphical models are today one of the most well used architectures for modelling and reasoning about knowledge with uncertainty. The most widely used subclass of these models is Bayesian networks that has found a wide range of applications both in industry and research. LÄS MER

  7. 5. Chain Graphs : Interpretations, Expressiveness and Learning Algorithms

    Författare :Dag Sonntag; M. Jose Peña; Nahid Shahmehri; Jirka Vomlel; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chain Graphs; Probabilitstic Grapical Models;

    Sammanfattning : Probabilistic graphical models are currently one of the most commonly used architectures for modelling and reasoning with uncertainty. The most widely used subclass of these models is directed acyclic graphs, also known as Bayesian networks, which are used in a wide range of applications both in research and industry. LÄS MER
