  1. 1. Approximations of Bayes Classifiers for Statistical Learning of Clusters

    Författare :Magnus Ekdahl; Timo Koski; Jukka Corander; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Pattern Recognition; Stochastic Complexity; Naïve Bayes; Bayesian Network; Classification; Clustering; Chow-Liu trees; Mathematical statistics; Matematisk statistik;

    Sammanfattning : It is rarely possible to use an optimal classifier. Often the classifier used for a specific problem is an approximation of the optimal classifier. Methods are presented for evaluating the performance of an approximation in the model class of Bayesian Networks. LÄS MER

  2. 2. On approximations and computations in probabilistic classification and in learning of graphical models

    Författare :Magnus Ekdahl; Jose Antonio Lozano; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematical statistics; factorizations; probabilistic classification; nodes; DNA strings; Mathematical statistics; Matematisk statistik;

    Sammanfattning : Model based probabilistic classification is heavily used in data mining and machine learning. For computational learning these models may need approximation steps however. LÄS MER

  3. 3. Den rätta tidens mått : Göthiska förbundet, fornforskningen och det antikvariska landskapet

    Författare :Torkel Molin; Umeå universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Göthiska förbundet; antiquarian research; landscape; heritage; Jacob Adlerbeth; Erik Gustaf Geijer; Johan Wallman; Nils Johan Ekdahl; romanticism; nationalism; history of archeology;

    Sammanfattning : The ideas that flourished among a small group of former Uppsala students that became the Göthiska förbundet on February 16, 1811, set in motion a process that changed views on why and how Sweden should manage its historic sites. This process of change achieved its goal with the passing of the new antiquities legislation in 1828. LÄS MER
