    Sammanfattning : The hidden Markov model (HMM) is one of the workhorse tools in, for example, statistical signal processing and machine learning. It has found applications in a vast number of fields, ranging all the way from bioscience to speech recognition to modeling of user interactions in social networks. LÄS MER

  3. 2. Markov Decision Problems in ATM Traffic Control

    Författare :Ernst Nordström; Lars Asplund; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer Systems; Datorteknik;

    Sammanfattning : This thesis discusses how to make cost-effective use of the communication resources in the Broadband Integrated Services Digital Network (B-ISDN), which is based on the Asynchronous Transfer Mode (ATM) switching and multiplexing technique.The thesis deals with two important functions in ATM traffic control, namely Call Admission Control (CAC) and routing, which affects both the network operator's revenue over time and the users' Quality of Service (QOS) and Grade of Service (GOS).
