1. 1. Hierarchical Fusion Approaches for Enhancing Multimodal Emotion Recognition in Dialogue-Based Systems : A Systematic Study of Multimodal Emotion Recognition Fusion Strategy

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Yuqi Liu; [2023]
   Nyckelord :Multimodal; emotion recognition; hierarchical fusion; context modeling; attention mechanism; feature-level fusion; decision-level fusion; machine learning; deep learning; Multimodal; emotion recognition; hierarkisk fusion; kontextmodellering; uppmärksamhetsmekanism; funktionssammanfogning på nivån för egenskaper; beslutsnivås-funktionssammanfogning; maskininlärning; djupinlärning;

   Sammanfattning : Multimodal Emotion Recognition (MER) has gained increasing attention due to its exceptional performance. In this thesis, we evaluate feature-level fusion, decision-level fusion, and two proposed hierarchical fusion methods for MER systems using a dialogue-based dataset. LÄS MER

3. 2. Multimodal Classification of Second-Hand E-Commerce Ads

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Ludvig Åberg; [2018]
   Nyckelord :Machine Learning; Classification; Multimodal Classification; Multimodal Learning; Representation Learning; Late Fusion; Early Fusion; Visual Attention; Marketplace; Second Hand; E-commerce; Blocket.se;

   Sammanfattning : In second-hand e-commerce, categorization of new products is typically done by the seller. Automating this process makes it easier to upload ads and could lower the number of incorrectly categorized ads. LÄS MER

4. 3. Change Detection in Stockholm between 1986 and 2006 using SPOT Multispectral and Panchromatic Data

   Master-uppsats, KTH/Geodesi och geoinformatik

   Författare :Ann-Mari Skrifvare; [2013]
   Nyckelord :change detection; remote sensing;

   Sammanfattning : With an increasing urban population in Sweden, expecting to reach 90% by 2050 (UN World Urbanization prospects, The 2011 Revision), this high level of urban population put pressure on functioning infrastructure, sufficient housing and need to monitor the environmental effects such as pollution and the effects of land use change. Stockholm County currently holds 22% of the population and accounts for nearly half of the urban growth in Sweden (Svensk Handelskammare). LÄS MER

5. 4. MACHINE VISION FOR AUTOMATICVISUAL INSPECTION OF WOODENRAILWAY SLEEPERS USING UNSUPERVISED NEURAL NETWORKS

   Master-uppsats, Datateknik

   Författare :Mihira Manne; [2009]
   Nyckelord :Artificial intelligence; Non-destructive testing; Rail inspection; Rail transportation; Unsupervised learning; Data fusion;

   Sammanfattning : The motivation for this thesis work is the need for improving reliability of equipment and quality of service to railway passengers as well as a requirement for cost-effective and efficient condition maintenance management for rail transportation. This thesis work develops a fusion of various machine vision analysis methods to achieve high performance in automation of wooden rail track inspection. LÄS MER

7. 5. Nonstationary feature extraction techniques for automatic classification of impact acoustic signals

   Master-uppsats, Datateknik

   Författare :Yasemi Bekiroglu; [2008]
   Nyckelord :railway sleepers;

   Sammanfattning : Condition monitoring of wooden railway sleepers applications are generallycarried out by visual inspection and if necessary some impact acoustic examination iscarried out intuitively by skilled personnel. In this work, a pattern recognition solutionhas been proposed to automate the process for the achievement of robust results. LÄS MER
