  1. 11. Exploring Feature Selection Techniques for Machine Learning-based Melanoma Skin Cancer Classification

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

    Författare :Thomas Eriksson Mueller; Viktor Fornstad; [2023]
    Nyckelord :Machine Learning; Feature Selection; Melanoma; Computer Aided Diagnosis; Bachelor Thesis; Maskininlärning; Attributurval; Melanom; Datorstödd Diagnostik; Kandidatarbete;

    Sammanfattning : One of the most globally common types of cancer is skin cancer, where melanoma is the most deadly form. An important and promising tool for diagnosing diseases such as skin cancer is computer aided diagnostics, a tool which utilizes machine learning to predict and classify cancer. LÄS MER

  3. 12. Theoretical investigation of Co-dependence in magnetic high-entropy alloys

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Johan-Michael Kurak; [2023]
    Nyckelord :;

    Sammanfattning : High-entropy alloys (HEA) is a class of materials consisting of multiple principal elements that often crystallize in simple lattices such as body-centered cubic, face-centered cubic and hexagonal close-packed structures. Many HEAsexhibit exceptional mechanical properties, e.g. LÄS MER

  4. 13. Fractal and entropy analysis of traditional and modernist building facades in street-level view : the case of Sweden’s growing cities

    Master-uppsats, SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)

    Författare :Alexis Ken Cartajenas; [2023]
    Nyckelord :fractal dimension; information entropy; street-level view; building façade; preference matrix;

    Sammanfattning : This study presents a quantitative analysis of traditional and modernist building facades in urban environments, focusing on the assessment of their complexity and coherence. Fractal and entropy analysis techniques were employed to objectively evaluate the differences between the two architectural styles within the preference matrix framework. LÄS MER

  5. 14. Dataset Drift in Radar Warning Receivers : Out-of-Distribution Detection for Radar Emitter Classification using an RNN-based Deep Ensemble

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för systemteknik

    Författare :Kevin Coleman; [2023]
    Nyckelord :Radar Emitter Classification; Pulse Descriptor Word; Out of Distribution Detection; Dataset Drift; Uncertainty Estimation; Deep Ensembles; Recurrent Neural Networks; LSTM;

    Sammanfattning : Changes to the signal environment of a radar warning receiver (RWR) over time through dataset drift can negatively affect a machine learning (ML) model, deployed for radar emitter classification (REC). The training data comes from a simulator at Saab AB, in the form of pulsed radar in a time-series. LÄS MER

  7. 15. Examining the Influence of Disfluencies on Reaction Time : An Exploratory Study Investigating the Impact of Entropy in Language

    Kandidat-uppsats, Linköpings universitet/Institutionen för datavetenskap

    Författare :Alexander Jansson; [2023]
    Nyckelord :Linguistics; Disfluency; Cognitive Science; Reaction Time; Hyponomy; Attention; Entropy;

    Sammanfattning : The current study aimed to investigate the effects of disfluencies, specifically filled pauses (FP) and unfilled pauses (UP), on reaction time (RT) to target words and hyponyms of target hypernyms(targets = target words + hyponyms of target hypernyms). Two experiments were conducted, withthe first experiment examining the impact of disfluencies on RTs to target words in utterances, whilethe second experiment explored their effect on hyponyms of target hypernyms.
