  2. 1. Reactive Concurrent Data Structures and Algorithms for Synchronization

    Author : Phuong Ha; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; non-blocking; reactive; multi-word atomic primitives; online algorithms; shared memory; concurrent data structures; distributed data structures; randomization; online financial problems; synchronization; spin-locks;

    Abstract : Parallelism plays a significant role in high-performance computing systems, from large clusters of computers to chip-multithreading (CMT) processors. Performance of the parallel systems comes not only from concurrently runningmore processing hardware but also from utilizing the hardware efficiently. READ MORE

  4. 2. Online news behavior

    Author : Adam Åbonde Garke; Handelshögskolan i Stockholm; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Abstract : Technological developments in the last decades have fundamentally transformed the news industry and the way citizens interact with media. Personal computers and smartphones abound, and internet has become the most common way citizens access news. READ MORE

  5. 3. Online Dimensionality Reduction

    Author : Kaito Ariu; Alexandre Proutiere; Mikael Johansson; Richard Combes; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : In this thesis, we investigate online dimensionality reduction methods, wherethe algorithms learn by sequentially acquiring data. We focus on two specificalgorithm design problems in (i) recommender systems and (ii) heterogeneousclustering from binary user feedback. READ MORE

  6. 4. Interactive Online Machine Learning

    Author : Agnes Tegen; Paul Davidsson; Jan A. Persson; Georg Krempl; Malmö universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Interactive Machine Learning; Active Learning; Machine Teaching; Online Learning;

    Abstract : With the Internet of Things paradigm, the data generated by the rapidly increasing number of connected devices lead to new possibilities, such as using machine learning for activity recognition in smart environments. However, it also introduces several challenges. The sensors of different devices might be mobile and of different types, i.e. READ MORE

  7. 5. Distributed Optimization and Control : Primal--Dual, Online, and Event-Triggered Algorithms

    Author : Xinlei Yi; Karl H. Johansson; Dimos V. Dimarogonas; John S. Baras; Antonis Papachristodoulou; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Distributed nonconvex optimization; distributed online convex optimization; distributed event-triggered control; primal-dual algorithm; stochastic gradient descent; zeroth-order algorithm; Electrical Engineering; Elektro- och systemteknik;

    Abstract : In distributed optimization and control, each network node performs local computation based on its own information and information received from its neighbors through a communication network to achieve a global objective. Although many distributed optimization and control algorithms have been proposed, core theoretical problems with important practical relevance remain. READ MORE
