  1. 1. Efficient Image Retrieval with Statistical Color Descriptors

    Författare :Linh Viet Tran; Reiner Lenz; Björn Kruse; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; color properties; images; statistical; content-based image retrieval CBIR ; non-parametric density estimators; image database; Kernel; Gram-Schmidt; geometry-based; Information technology; Informationsteknologi;

    Sammanfattning : Color has been widely used in content-based image retrieval (CBIR) applications. In such applications the color properties of an image are usually characterized by the probability distribution of the colors in the image. LÄS MER

  2. 2. Statistical Inference of Information in Networks : Causality and Directed Information Graphs

    Författare :Sina Molavipour; Mikael Skoglund; Deniz Gündüz; KTH; []

    Sammanfattning : Over the last decades, the advancements in measurement, collection, and storage of data have provided tremendous amounts of information. Thus, it has become crucial to extract valuable features and analyze the characteristics of data. As we study more complex systems (e.g. LÄS MER

  3. 3. Statistical Methods for Computational Markets : Proportional Share Market Prediction and Admission Control

    Författare :Thomas Sandholm; Magnus Boman; Mark Baker; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Distributed Systems; Grid Computing; Performance Analysis; Workload Modeling; Middleware; Quality of Service; Prediction; Admission Control; Computer and systems science; Data- och systemvetenskap;

    Sammanfattning : We design, implement and evaluate statistical methods for managing uncertainty when consuming and provisioning resources in a federated computational market. To enable efficient allocation of resources in this environment, providers need to know consumers' risk preferences, and the expected future demand. LÄS MER

  4. 4. Dynamic Resampling for Preference-based Evolutionary Multi-objective Optimization of Stochastic Systems : Improving the efficiency of time-constrained optimization

    Sammanfattning : In preference-based Evolutionary Multi-objective Optimization (EMO), the decision maker is looking for a diverse, but locally focused non-dominated front in a preferred area of the objective space, as close as possible to the true Pareto-front. Since solutions found outside the area of interest are considered less important or even irrelevant, the optimization can focus its efforts on the preferred area and find the solutions that the decision maker is looking for more quickly, i.

  5. 5. Mobile Supported e-Government Systems : Analysis of the Education Management Information System (EMIS) in Tanzania

    Författare :Gudrun Wicander; John-Sören Pettersson; Anders G. Nilsson; Peter Rönnlund; Louise Yngström; Karlstads universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; e-Government systems; mobile telephony; SMS; blended digital system; education management; information systems; systems theory; developing countries; Tanzania; ICT4D; M4D; Information Systems; Informatik;

    Sammanfattning : e-Government systems are considered by both governments and international organisations to improve administration and management. In Tanzania, an e-government system for education administration, EMIS, is partly implemented but shows several limitations. LÄS MER
