    Författare :Cheng Zhang; Hedvig Kjellström; Jordan Boyd-Graber; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Computer Science; Datalogi;

    Sammanfattning : Over the past two centuries the industrial revolution automated a great part of work that involved human muscles. Recently, since the beginning of the 21st century, the focus has shifted towards automating work that is involving our brain to further improve our lives. LÄS MER

  2. 2. Passive Optical Top-of-Rack Interconnect for Data Center Networks

    Författare :Yuxin Cheng; Jiajia Chen; Lena Wosinska; Matteo Fiorani; Qiong Zhang; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Optical communications; data center interconnects; MAC protocol; dynamic bandwidth allocation.; Informations- och kommunikationsteknik; Information and Communication Technology;

    Sammanfattning : Optical networks offering ultra-high capacity and low energy consumption per bit are considered as a good option to handle the rapidly growing traffic volume inside data center (DCs). However, most of the optical interconnect architectures proposed for DCs so far are mainly focused on the aggregation/core tiers of the data center networks (DCNs), while relying on the conventional top-of-rack (ToR) electronic packet switches (EPS) in the access tier.

  3. 3. Fine-Grained and Continual Visual Recognition for Assisting Visually Impaired People

    Författare :Marcus Klasson; Hedvig Kjellström; Cheng Zhang; Davide Bacciu; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fine-Grained Image Recognition; Continual Learning; Visually Impaired People; Image Classification; Replay Scheduling; Datalogi; Computer Science;

    Sammanfattning : In recent years, computer vision-based assistive technologies have enabled visually impaired people to use automatic visual recognition on their mobile phones. These systems should be capable of recognizing objects on fine-grained levels to provide the user with accurate predictions. LÄS MER

  4. 4. A Further Step of Causal Discovery towards Real-World Impacts

    Författare :Ruibo Tu; Hedvig Kjellström; Cheng Zhang; Robin Evans; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; causal discovery; missing data; fairness; functional causal model; Datalogi; Computer Science;

    Sammanfattning : The goal of many sciences is to find causal relationships and understand underlying mechanisms. As the golden standard for finding causal relationships, doing randomized experiments can be difficult or impossible in some applications; hence, determining underlying causal relationships purely from observational data, i.e. LÄS MER
