  1. 21. Accelerating Convergence of Large-scale Optimization Algorithms

    Författare :Euhanna Ghadimi; Mikael Johansson; Angelia Nedich; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Convex optimization; Large-scale systems; First-order methods; Convergence analysis; ADMM; Optimization algorithms; Electrical Engineering; Elektro- och systemteknik; Matematik; Mathematics;

    Sammanfattning : Several recent engineering applications in multi-agent systems, communication networks, and machine learning deal with decision problems that can be formulated as optimization problems. For many of these problems, new constraints limit the usefulness of traditional optimization algorithms. LÄS MER

  3. 22. Decentralized Constrained Optimization: a Novel Convergence Analysis

    Författare :Firooz Shahriari Mehr; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Constrained optimization; Decentralized optimal transport; Distributed optimization; Multi-agent systems; Convergence analysis; Convex optimization;

    Sammanfattning : One reason for the spectacular success of machine learning models is the appearance of large datasets. These datasets are often generated by different computational units or agents and cannot be processed on a single machine due to memory and computing limitations. LÄS MER

  4. 23. Convergence Analysis and Design of Multiple Concatenated Codes

    Författare :Fredrik Brännström; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; extrinsic information transfer EXIT function; convergence analysis; Multiple concatenated codes; code search; scheduling; parameter estimation; iterative decoding; EXIT chart; puncturing;

    Sammanfattning : The objective of this thesis is to develop a methodology for designing efficient multiple concatenated coding schemes, consisting of two or more constituent codes, concatenated in serial or in parallel. Extrinsic information transfer (EXIT) analysis is found to be a suitable and versatile analysis tool for such codes and thus, the design methodology is based almost entirely on this technique.

  5. 24. Pretend that it is Real! Convergence Culture in Practice

    Författare :Marie Denward; Jay Bolter; Malmö högskola; []
    Nyckelord :media convergence; alternate reality games; broadcast television; pervasive games; culture of production; ethnography; game design; game development; transmedia storytelling; pervasive live action role-playing; fiction; reality; participatory culture; audience; interactivity; public service broadcasting; media studies;

    Sammanfattning : Mediekonvergens definieras och förklaras oftast som en teknisk och industriell företeelse, som den process där ny teknik anpassas till den befintliga medieindustrin och dess produktionskulturer. I dagens hybrida medielandskap kan mediekonvergens också beskrivas som den sociala process och de aktiviteter som medieanvändare deltar i när de rör sig mellan olika medier i jakt på underhållning och erfarenheter.

  7. 25. Discretizations of nonlinear dissipative evolution equations. Order and convergence

    Författare :Eskil Hansen; Numerisk analys; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; kontroll; systems; numerisk analys; control; Datalogi; numerical analysis; Computer science; B-convergence; Dissipative maps; Logarithmic Lipschitz constants; Galerkin methods; Nonlinear evolution equations; Time discretizations; system;

    Sammanfattning : The theme of this thesis is to study discretizations of nonlinear dissipative evolution equations, which arise in e.g. advection-diffusion-reaction processes. LÄS MER
