  1. 6. Rainfall-Runoff Modelling Using Artificial Neural Networks (ANNs)

    University dissertation from Department of Water Resources Engineering, Lund Institute of Technology, Lund University

    Author : Aman Mohammad Kalteh; [2007]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydrogeology; geographical and geological engineering; Hydrogeologi; teknisk geologi; teknisk geografi; Self-organizing map; Feed-forward multilayer perceptron; Forecasting; Hydrological modelling; Missing values; Rainfall-runoff modelling; Estimation; Artificial neural networks;

    Abstract : Over the last decades or so, artificial neural networks (ANNs) have become one of the most promising tools for modelling hydrological processes such as rainfall-runoff processes. In most studies, ANNs have been demonstrated to show superior result compared to the traditional modelling approaches. READ MORE

  2. 7. Artificial neural networks for assessment of patients with suspected acutemyocardial infarction

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Johan Ellenius; [2000]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medical sciences; Artificial neural network; decision-support systems; transferability; acute myocardial infarction; infarct size; nondiagnostic ECG; myoglobin; CK-MB; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; medicinsk informatik; medicinsk informatik;

    Abstract : An early diagnosis within the first hours after onset of symptoms is essential for the optimal treatment of patients admitted with chest pain of suspected cardiac origin. In the majority of patients, the 12-lead ECG is nondiagnostic on admission. READ MORE

  3. 8. On Data Mining and Classification Using a Bayesian Confidence Propagation Neural Network

    University dissertation from Stockholm : Numerisk analys och datalogi

    Author : Roland Orre; [2003]
    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.
