  1. 6. Artificial neural networks for assessment of patients with suspected acutemyocardial infarction

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Johan Ellenius; Uppsala universitet.; [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

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

    University dissertation from Stockholm : Numerisk analys och datalogi

    Author : Roland Orre; KTH.; [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.

  3. 8. Morphometric and Landscape Feature Analysis with Artificial Neural Networks and SRTM data Applications in Humid and Arid Environments

    University dissertation from Stockholm : KTH

    Author : Amir Houshang Ehsani; KTH.; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Self Organizing Map; Neural Network; Morphometric Feature; Landscape; Yardang; Lut Desert; Potential natural vegetation; geoecosystem; Landform; Landsat ETM ; Morphometric Parameters; SRTM; Resolution; Curvatures; DEM.; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : This thesis presents a semi-automatic method to analyze morphometric features and landscape elements based on Self Organizing Map (SOM) as an unsupervised Artificial Neural Network algorithm in two completely different environments: 1) the Man and Biosphere Reserve “Eastern Carpathians” (Central Europe) as a complex mountainous humid area and 2) Lut Desert, Iran, a hyper arid region characterized by repetition of wind-eroded features.In 2003, the National Aeronautics and Space Administration (NASA) released the SRTM/ SIR-C band data with 3 arc seconds (approx.

  5. 10. Sense of Touch in Robots

    University dissertation from Stockholm : Fysik

    Author : Magnus Johnsson; Lunds universitet.; Lund University.; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; touch perception; neural network; robot hand; brain model; cognitive model; robot model; tensor network; associative self-organizing map; SOM; proprioception;

    Abstract : This thesis discusses a number of robot touch perception systems. All these systems are self-organizing and model different aspects of human touch perception. The thesis starts out with introductions to the anatomy and the physiology of the human hand. READ MORE
