  1. 1. Evaluating DCNN architecturesfor multinomial area classicationusing satellite data

    Master-uppsats, Linköpings universitet/Artificiell intelligens och integrerade datorsystem

    Författare :Karol Wojtulewicz; Viktor Agbrink; [2020]
    Nyckelord :Segmentation; FCN; Computer Vision; Autoencoder; Area classification;

    Sammanfattning : The most common approach to analysing satellite imagery is building or object segmentation,which expects an algorithm to find and segment objects with specific boundaries thatare present in the satellite imagery. The company Vricon takes satellite imagery analysisfurther with the goal of reproducing the entire world into a 3D mesh. LÄS MER

  3. 2. Machine learning algorithms in a distributed context

    Kandidat-uppsats, Linköpings universitet/Institutionen för datavetenskap

    Författare :Samuel Johansson; Karol Wojtulewicz; [2018]
    Nyckelord :Machine learning; ensemble algorithms; hard data partitioning; decision trees;

    Sammanfattning : Interest in distributed approaches to machine learning has increased significantly in recent years due to continuously increasing data sizes for training machine learning models. In this thesis we describe three popular machine learning algorithms: decision trees, Naive Bayes and support vector machines (SVM) and present existing ways of distributing them. LÄS MER

  4. 3. Modelling the Cross-Country Trafficability with Geographical Information Systems

    Magister-uppsats, Institutionen för datavetenskap

    Författare :Aleksander Karol Gumos; [2005]
    Nyckelord :GIS; Cross-Country Trafficability; Digital Elevation Model DEM ; TIN; Hydrologic Modelling; Soil Mechanics; Compound Topographic Index; Map Algebra; Multicriteria Evaluation; Map-Based Modelling; Raster Data Model; Cost-Weightet Distance Functions; Spatial Modelling; 3D-Aided Scene Animations;

    Sammanfattning : The main objectives of this work were to investigate Geographical Information Systems techniques for modelling a cross-country trafficability. To accomplished stated tasks, reciprocal relationships between the soil deposits, local hydrology, geology and geomorphology were studied in relation to the study area in South-Eastern Sweden. LÄS MER
