  1. 1. Feature Selection for Microarray Data via Stochastic Approximation

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

    Författare :Erik Rosvall; [2024-03-18]
    Nyckelord :feature selection; feature ranking; microarray data; stochastic approximation; Barzilai and Borwein method; Machine Learning; AI;

    Sammanfattning : This thesis explores the challenge of feature selection (FS) in machine learning, which involves reducing the dimensionality of data. The selection of a relevant subset of features from a larger pool has demonstrated its effectiveness in enhancing the performance of various machine learning algorithms. LÄS MER

  3. 2. Reconstructing point patterns from spatially aggregated data

    Master-uppsats, Göteborgs universitet/Institutionen för matematiska vetenskaper

    Författare :Jens Michelsen; [2024-03-13]
    Nyckelord :lorem; ipsum; dolor; sit; amet; consectetur; adipisicing; elit; sed; do.;

    Sammanfattning : In this thesis we explore the ability to reconstruct samples (point configurations) from a point process, based only on the information contained in spatially aggregated data, namely the number of points in the partitions of a larger region. The ability to reconstruct a point configuration, in such a way that it retains most of it’s statistical properties, could be useful in cases where one is faced with a mixed dataset; some regions containing the full point configuration data, while other regions only contain aggregated data, i.

  4. 3. Är alla personuppgifter direkt eller indirekt känsliga? – Om yttergränserna för tillämpningen av artikel 9 i GDPR i ljuset av C-184/20 Etikosdomen

    Magister-uppsats, Göteborgs universitet/Juridiska institutionen

    Författare :Arad Aslrousta; [2024-03-05]
    Nyckelord :General Data Protection Regulation GDPR ; Article 9; Indirect; Indicative; Unambiguous; Sensitive; Personal data; Intellectual operation; Probability; Purposive approach; Contextual approach; The precautionary principle; Principle of proportionality; Freedom to conduct a business;

    Sammanfattning : In August 2022, the CJEU confirmed the existence of indirectly sensitive personal data, leaving critical questions unanswered. While certain data may unequivocally and indirectly disclose sensitive information, a vast amount of data can be used to indirectly deduce such sensitive data only through mere indication. LÄS MER

  5. 4. Data analysis for predictive maintenance and potential challenges associated with the technology integration of steel industry machines.

    Master-uppsats, Högskolan i Gävle/Elektronik

    Författare :Pradip Nath; [2024]
    Nyckelord :Data Science; Data processing; Industrial Manufacturing; System Identification; Predictive maintenance; Conditional monitoring; Statistical Analysis; Signal processing; Hydraulic System; IoT; Sustainable Maintenance; Data vetenskap; Databehandling; Industriell tillverkning; System identifiering; Prediktivt underhåll; Tillståndsövervakning; Statistisk analys; Signal behandling;

    Sammanfattning : The recharge is the focus of data analysis of the different situations with the integration of the system and development of the two-stage 2/2 proportional cartridge valve for the steel industry machine. Using the statistical analysis technique to visualize the valve signal data behavior identify the accuracy of the machine data and apply the statistical feature extracting model using classification and clustering algorithms of real-time data analysis for the manufacturing.

  7. 5. Ursprungslandseffektens påverkan vid bilköp : En studie av svenska konsumenters uppfattning av kinesiska produkter

    Kandidat-uppsats, Högskolan i Gävle/Avdelningen för ekonomi

    Författare :Philip Grane Elisson; Johanna Lindroth; [2024]
    Nyckelord :Country-of-origin COO ; Country-of-origin effects; Made in China; Purchase decision;

    Sammanfattning : Syfte: Syftet med denna studie är att undersöka vilka effekter COO har på svenska konsumenter gällande varumärken och produkter med ursprung från Kina.  Metod: Studien har utgått från en deduktiv process med en kvantitativ metod. LÄS MER
