  4. 3. Complexity-aware Decision-making with Applications to Large-scale and Human-in-the-loop Systems

    Författare :Elis Stefansson; Karl H. Johansson; Henrik Sandberg; Iman Shames; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Complexity-aware Decision-making; Automata Theory; Automatic Control; Optimal Control; Kolmogorov Complexity; Hierarchical Finite State Machines; Large-scale Systems; Human-in-the-loop; Game Theory; Human Decision-making; Autonomous vehicles; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : This thesis considers control systems governed by autonomous decision-makers and humans. We formalise and compute low-complex control policies with applications to large-scale systems, and propose human interaction models for controllers to compute interaction-aware decisions. LÄS MER

  5. 4. Manifold learning and representations for image analysis and visualization

    Författare :Anders Brun; Hans Knutsson; Magnus Herberthson; Carl-Fredrik Westin; Reiner Lenz; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; manifold learning; image analysis; signal processing; diffusion tensor mri; Medical informatics; Medicinsk informatik;

    Sammanfattning : We present a novel method for manifold learning, i.e. identification of the low-dimensional manifold-like structure present in a set of data points in a possibly high-dimensional space. The main idea is derived from the concept of Riemannian normal coordinates. LÄS MER

  7. 5. On the use of traffic flows for improved transportation systems : Mathematical modeling and applications
