    Sammanfattning : A successful articial cognitive agent needs to integrate its perception of the environment with reasoning and actuation. A key aspect of this integration is the perceptual-symbolic correspondence, which intends to give meaning to the concepts the agent refers to { known as Anchoring. However, perceptual representations alone (e.g. LÄS MER

    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; speech enhancement; noise reduction; linear predictive coe±cients; autoregressive; codebooks; maximum-likelihood; Bayesian; nonstationary noise; blind source separation.; Telecommunication; Telekommunikation;

    Sammanfattning : Speech is a fundamental means of human communication. In the last several decades, much effort has been devoted to the efficient transmission and storage of speech signals. With advances in technology making mobile communication ubiquitous, communications anywhere has become a reality. LÄS MER

  4. 3. Opinion-Based Systems : The Cooperative Perspective on Knowledge-Based Decision Support

    Författare :Göran Forslund; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : During the last fifteen years expert systems have successfully been applied to a number of difficult problems in a variety of different application domains. Still, the task of actually developing these systems has been much harder than was predicted, and among systems delivered many have failed to meet user acceptance. LÄS MER

  7. 5. Statistical expert systems : a special application area for knowledge-based computer methodology

    Författare :Shamsul I. Chowdhury; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : The study investigates the purposes, functions and requirements of statistical expert systems and focuses attention on some unique characteristics of this subcategory of knowledge-based systems. Statistical expert systems have been considered in this thesis as one approach to improve statistical software and extend their safe usability to a broad category of users in different phases of a statistical investigation.
