  1. 16. Understanding Sales Performance Using Natural Language Processing - An experimental study evaluating rule-based algorithms in a B2B setting

    Master-uppsats, Stockholms universitet/Institutionen för data- och systemvetenskap

    Författare :Angelica Smedberg; [2023]
    Nyckelord :NLP; Sentiment Analysis; Ruled-based algorithms; TextBlob; VADER; Naïve Bayes; Machine Learning;

    Sammanfattning : Natural Language Processing (NLP) is a branch in data science that marries artificial intelligence with linguistics. Essentially, it tries to program computers to understand human language, both spoken and written. Over the past decade, researchers have applied novel algorithms to gain a better understanding of human sentiment. LÄS MER

  3. 17. AI/ML Development for RAN Applications : Deep Learning in Log Event Prediction

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

    Författare :Yuxin Sun; [2023]
    Nyckelord :LSTM; Anomaly Detection; Failure Prediction; Log Mining; Deep Learning; LSTM; Anomali Detection; Failure Prediction; Log Mining; Deep Learning;

    Sammanfattning : Since many log tracing application and diagnostic commands are now available on nodes at base station, event log can easily be collected, parsed and structured for network performance analysis. In order to improve In Service Performance of customer network, a sequential machine learning model can be trained, test, and deployed on each node to learn from the past events to predict future crashes or a failure.

  4. 18. Investigation on the natural indigo dye for cotton fabric by using supercritical carbon dioxide

    Master-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Ryoi Takamatsu; [2023]
    Nyckelord :Dyeing; supercritical carbon dioxide; indigo; cotton; eco-friendly; textile;

    Sammanfattning : Concerns about the environmental impact of the textile industry are increasing, and there is an urgent need to develop and implement sustainable technologies. In particular, the environmental impact of dyeing, which emits a large amount of wastewater and chemicals, is one production process that needs to be resolved. LÄS MER

  5. 19. Lek, lärande & rörelse på bostadsgården med dagvatten som resurs

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

    Författare :Anna Forsfält Ljungberg; Matilda Andersson; [2023]
    Nyckelord :multifunktionalitet; vattenlek; inlärning; rörelse; dagvatten; dagvattenhantering; bostadsgård; ; vattengestaltning; ekostaden; Augustenborg; Bo01; resurshantering;

    Sammanfattning : Föreliggande studie utreder hur dagvatten kan användas som resurs för att främja lek, lärande och rörelse på bostadsgården. I urbana sammanhang ses ofta dagvatten som ett problem då stora vattenflöden överbelastar vår infrastruktur med förödande konsekvenser. LÄS MER

  7. 20. Language Models as Evaluators : A Novel Framework for Automatic Evaluation of News Article Summaries

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

    Författare :Celine Helgesson Hallström; [2023]
    Nyckelord :Natural Language Processing; Large Language Models; Automatic Text Evaluation; Text Summarization; Multilingualism; Naturlig Språkbehandling; Stora Språkmodeller; Automatisk Textutvärdering; Textsammanfattning; Flerspråkighet;

    Sammanfattning : The advancements in abstractive summarization using Large Language Models (LLMs) have brought with it new challenges in evaluating the quality and faithfulness of generated summaries. This thesis explores a human-like automated method for evaluating news article summaries. LÄS MER
