  1. 1. First-Order Algorithms for Communication Efficient Distributed Learning

    Författare :Sarit Khirirat; Mikael Johansson; Martin Jaggi; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Communication efficient learning; Optimization algorithms; Quantization; Error compensation; First-order algorithms; Stochastic gradient descent; Tillämpad matematik och beräkningsmatematik; Applied and Computational Mathematics; Optimeringslära och systemteori; Optimization and Systems Theory; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Technological developments in devices and storages have made large volumes of data collections more accessible than ever. This transformation leads to optimization problems with massive data in both volume and dimension. LÄS MER

  3. 2. First-Order Algorithms for Communication Efficient Distributed Learning

    Författare :Sarit Khirirat; Mikael Johansson; Tong Zhang; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Communication efficient learning; Optimization algorithms; Quantization; Error compensation; First-order algorithms; Stochastic gradient descent; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Innovations in numerical optimization, statistics and high performance computing have enabled tremendous advances in machine learning algorithms, fuelling applications from natural language processing to autonomous driving.To deal with increasing data volumes, and to keep the training times of increasingly complex machine learning models reasonable, modern optimization algorithms distribute both data and computations over a large number of machines.

  4. 3. Probabilistic time estimation in tunnel projects

    Författare :Mohammad Mohammadi; Johan Spross; Fredrik Johansson; Larsson Stefan; Anna Kadefors; Lars-Olof Dahlström; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cost overrun; Tunneling projects; Probabilistic approaches; time estimation; Kostnadsöverskridande; tunnelprojekt; sannolikhetsmetoder; tidsuppskattning; Soil and Rock Mechanics; Jord- och bergmekanik;

    Sammanfattning : Transport infrastructure projects, including tunneling, suffer from timedelays and cost overrun. A literature review shows that the effect ofuncertainty has been neglected in explaining time and cost overrunmeaning that technical explanations matter. LÄS MER
