  1. 1. Optimising Machine Learning Models for Imbalanced Swedish Text Financial Datasets: A Study on Receipt Classification : Exploring Balancing Methods, Naive Bayes Algorithms, and Performance Tradeoffs

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för datavetenskap och medieteknik (DM)

    Författare :Li Ang Hu; Long Ma; [2023]
    Nyckelord :Imbalanced datasets; Swedish text financial datasets; Accuracy; Matthews correlation coefficient; Recall; Multinomial Naive Bayes; SMOTE; TomekLinks; Performance optimization;

    Sammanfattning : This thesis investigates imbalanced Swedish text financial datasets, specifically receipt classification using machine learning models. The study explores the effectiveness of under-sampling and over-sampling methods for Naive Bayes algorithms, collaborating with Fortnox for a controlled experiment. LÄS MER

  3. 2. A General Purpose Near Data Processing Architecture Optimized for Data-intensive Applications

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Xingda Li; Haidi Hu; [2023]
    Nyckelord :Technology and Engineering;

    Sammanfattning : In recent years, as Internet of Things (IoT) and machine learning technologies have advanced, there has been increasing interest in the study of energy-efficient and flexible architectures for embedded systems. To bridge the performance gap between microprocessors and memory systems, Near-Data Processing (NDP) was introduced. LÄS MER

  4. 3. Framtidens män(niskor) : En bild- och diskursanalys av Ex Machina utifrån kritiska framtidsstudier

    Kandidat-uppsats, Södertörns högskola/Idéhistoria

    Författare :Cäcilia Li; [2023]
    Nyckelord :Critical Future Studies; sociotechnical imaginaries; Ex Machina; artificial intelligence; cyborg; intersectionality.;

    Sammanfattning : This essay examines visions of the future in Alex Garlands 2015 film Ex Machinausing critical futures studies and posthumanist theories. The aim is to make visible howfutures are constructed and how artificial bodies are coded based on ideas of the future. LÄS MER

  5. 4. Gender performance in livestream shopping - An empirical study of the most popular male host for beauty product in China

    D-uppsats, Handelshögskolan i Stockholm/Institutionen för företagande och ledning

    Författare :Zhaoze Wang; Xiaorui Hu; [2021]
    Nyckelord :marketing; consumer; livestream shopping; gender performance;

    Sammanfattning : This thesis explores how a successful male beauty host and his viewers perform gender roles in the Chinese livestream shopping. Although a vast scope of research has approached different gender-related topics in marketing and consumer research, livestream shopping has remained unexplored. LÄS MER

  7. 5. Phase field modelling of LLZO/LCO cathode-electrolyte interfaces in solid state batteries

    Master-uppsats, Uppsala universitet/Strukturkemi

    Författare :Michele Riva; [2018]
    Nyckelord :LLZO; LCO; phase; field; phase-field; phasefield; solid; state; solid-state; solidstate; battery; batteries; sintering; model; modelling;

    Sammanfattning : This work describes two phase field models for the simulation of the interface evolution between a LiCoO2 cathode (LCO) and a Li7La3Zr2O12 solid electrolyte (LLZO) in a Li-metal/LLZO/LCO battery during high temperature sintering. In these conditions atomic species tend to diffuse into the opposing material, creating an intermediate layer of mixed composition which resists the movement of lithium ions. LÄS MER
