  1. 1. Information-Theoretic Generalization Bounds: Tightness and Expressiveness

    Författare :Fredrik Hellström; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; information theory; neural networks; generalization; statistical learning; meta learning; PAC-Bayes; Machine learning;

    Sammanfattning : Machine learning has achieved impressive feats in numerous domains, largely driven by the emergence of deep neural networks. Due to the high complexity of these models, classical bounds on the generalization error---that is, the difference between training and test performance---fail to explain this success. LÄS MER

  3. 2. Information infrastructure risk : perspectives, practices & technologies

    Författare :Lars Öbrand; Jonny Holmström; Ole Hanseth; Mari-Klara Stein; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Risk; risk management; practice research; information infrastructure theory;

    Sammanfattning : This dissertation investigates the nature and management of information infrastructure risks in organizations. Specifically, it examines how practitioners identify and manage threats towards their organizational aims, and suggests ways of achieving sustainable risk management, in settings characterized by the integration of information technology (IT) and organizational processes.

  4. 3. Optimization and Fundamental Insights in Full-Duplex Cellular Networks

    Författare :Jose Mairton B. da Silva Jr.; Carlo Fischione; Gabor Fodor; Geoffrey Ye Li; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; full-duplex; optimization; power control; assignment; beamforming; millimeter wave; self-interference; multi-antenna; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : The next generations of cellular networks are expected to provide explosive data rate transmissions and very low latencies. To meet such demands, one of the promising wireless transmissions candidates is in-band full-duplex communications, which enable wireless devices to simultaneously transmit and receive on the same frequency channel.

  5. 4. Guaranteeing Generalization via Measures of Information

    Författare :Fredrik Hellström; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; PAC-Bayes; statistical learning; information theory; Machine learning; neural networks.; generalization;

    Sammanfattning : During the past decade, machine learning techniques have achieved impressive results in a number of domains. Many of the success stories have made use of deep neural networks, a class of functions that boasts high complexity. Classical results that mathematically guarantee that a learning algorithm generalizes, i.e. LÄS MER

  7. 5. Information, Voting Behavior and Electoral Accountability
