  1. 1. Continuous Parallel Approximate Frequent Elements Queries on Data Streams

    Master-uppsats, Göteborgs universitet/Institutionen för data- och informationsteknik

    Författare :Victor Jarlow; [2021-10-06]
    Nyckelord :computer science; big data; Space-Saving; Misra-Gries summary; frequent items; frequent elements; concurrent programming; Delegation Sketch; domain splitting; Count-Min Sketch; Majority algorithm; pproximate frequent-elements algorithm; approximate top-k elements algorithm;

    Sammanfattning : The frequent elements problem involves processing a stream of elements and finding all elements that occur more than a given fraction of the time. A relaxed versionof this problem is the -approximate elements problem which allows some false positives. LÄS MER

  2. 2. WANNA BE ON TOP? The Hyperparameter Search for Semantic Change's Next Top Model

    Master-uppsats, Göteborgs universitet / Institutionen för filosofi, lingvistik och vetenskapsteori

    Författare :Kate Viloria; [2021-09-22]
    Nyckelord :semantic change; language change; diachronic word embeddings;

    Sammanfattning : Lexical semantic change (LSC) detection through the use of diachronic corpora and computational methods continues to be a prevalent research area in language change (Tahmasebi et al., 2018). LÄS MER

  3. 3. Simulating an Ecosystem

    Kandidat-uppsats, Göteborgs universitet/Institutionen för data- och informationsteknik

    Författare :Aron Sjöberg; Emil Wingårdh; Erik Söderpalm; Theo Wiik; Viktor Fredholm; Yvonne Hansson; [2021-09-14]
    Nyckelord :ecosystem; simulation; Unity; genetic algorithm; evolution; natural selection;

    Sammanfattning : Simulations are computer programs based on models, used to imitate real-life scenarios. Simulating an ecosystem is a great challenge given the various factors thatinteract and animals that coexist. LÄS MER

  4. 4. Interactive Ecosystem Simulator

    Kandidat-uppsats, Göteborgs universitet/Institutionen för data- och informationsteknik

    Författare :JOHAN ATTERFORS; CARL HOLMBERG; ALEXANDER HUANG; ROBIN KARHU; BRAGE LAE; ALEXANDER LARSSON VAHLBERG; [2021-09-07]
    Nyckelord :Ecosystem; Simulation; Unity; AI; ML; RL; ABM; GA; PCG; Welford;

    Sammanfattning : As ecosystems are complex domains, both analytical and computer-aided modelscan aid in gaining insights about their dynamics. One such computer-aided modelis the concept of ecosystem simulation. This project aims to build an interactiveand visual ecosystem simulation in the Unity game engine. LÄS MER

  5. 5. Multi-objective optimization for placing airspace surveillance observers

    Master-uppsats, Göteborgs universitet/Institutionen för data- och informationsteknik

    Författare :Amanda Anderson; [2021-08-13]
    Nyckelord :Facility location; multi-objective optimization; ant colony algorithm; genetic algorithm; pareto optimal; observer placement; 3D viewshed;

    Sammanfattning : Reconnaissance is an important aspect of military planning. Tools that help an alysts monitor and make informed choices are vital for avoiding costly situations.The use of ground-based radar sensors is a common method for monitoring for bothland-based and airborne threats.
