  2. 1. The use of Bayesian confidence propagation neural network in pharmacovigilance

    Author : Andrew Bate; Umeå universitet; []
    Keywords : adverse drug reactions; pharmacovigilance; signal detection; spontaneous reporting; data mining; Bayesian statistics; BCPNN; neural network; medicinsk farmakologi; Medical Pharmacology;

    Abstract : The WHO database contains more than 2.8 million case reports of suspected adverse drug reactions reported from 70 countries worldwide since 1968. The Uppsala Monitoring Centre maintains and analyses this database for new signals on behalf of the WHO Programme for International Drug Monitoring. READ MORE

  4. 2. On Data Mining and Classification Using a Bayesian Confidence Propagation Neural Network

    Author : Roland Orre; KTH; []
    Keywords : data mining; bcpnn; classification; neural network;

    Abstract : The aim of this thesis is to describe how a statisticallybased neural network technology, here named BCPNN (BayesianConfidence Propagation Neural Network), which may be identifiedby rewriting Bayes' rule, can be used within a fewapplications, data mining and classification with credibilityintervals as well as unsupervised pattern recognition.BCPNN is a neural network model somewhat reminding aboutBayesian decision trees which are often used within artificialintelligence systems.

  5. 3. Neural Network Ensembles and Combinatorial Optimization with Applications in Medicine

    Author : Henrik Haraldsson; Beräkningsbiologi och biologisk fysik - Genomgår omorganisation; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; numerisk analys; machine learning; artificial neural networks; ensemble methods; feature extraction; ECG; combinatorial optimization; mean field annealing; Computer science; numerical analysis; systems; Datalogi; control; system; kontroll; Artificial intelligens; Artificiell intelligens; Fysicumarkivet A:2003:Haraldsson;

    Abstract : Artificial neural network (ANN) and combinatorial optimization algorithms are developed, and applied to the medical domain. A novel method for training an ensemble of ANN is presented, based on random weight updates alternated with replication of networks with low error. READ MORE

  6. 4. Classification of large pollen datasets using neural networks with application to mapping and modelling pollen data

    Author : Björn Holmqvist; Kvartärgeologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis concerns the usage of large pollen databases and their application to mapping and modelling past vegetation. Maps of past taxon distributions are generated and classification techniques are used to compile maps of past woodland types. READ MORE

  7. 5. Human Vehicle Interaction Drivers’ Body and Visual Behaviour and Tools and Process for Analysis

    Author : Lars Hanson; Ergonomi och aerosolteknologi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Working process; Vision; Safety; Reach; Posture; Neural network; Fuzzy logic; Ergonomics; Driver behaviour; Documentation; Digital human modelling; Comfort; Button location; Car interior; Technology of other products; Produktteknik allmän ;

    Abstract : Vehicle design is characterized by a high number of compromises. The special role of human factors in the process is to ensure that the compromises do not occur at the expense of the driver and passengers. READ MORE
