    Sammanfattning : Over half of the world’s population live in urban areas, a trend which is expected to only grow as we move further into the future. With this increasing trend in urbanisation, challenges are presented in the form of the management of urban infrastructure systems. LÄS MER

  5. 19. Machine Behavior Development and Analysis using Reinforcement Learning

    Författare :Yuan Gao; Ginevra Castellano; Elin Anna Topp; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reinforcement learning; robotics; human robot interaction; Computer Science; Datavetenskap;

    Sammanfattning : We are approaching a future where robots and humans will co-exist and co-adapt. To understand how can a robot co-adapt with humans, we need to understand and develop efficient algorithms suitable for our interactive purposes. Not only it can help us to advance the field of robotics but also it can help us to understand ourselves. LÄS MER
