  1. 11. PV self-consumption: Regression models and data visualization

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Martos Tóth; [2022]
    Nyckelord :Self-Consumption; photovoltaics; battery; machine learning; solar energy; random forest; k-nearest neighbor; multi-layer perceptron; lasso regression; ridge regression; linear regression; Egenanvändning; photovoltaics; batteri; maskininlärning; solenergi; random forest; k-nearest neighbors; multi-layer perceptron; lasso regression; ridge regression; linjär regression;

    Sammanfattning : In Sweden the installed capacity of the residential PV systems is increasing every year. The lack of feed-in-tariff-scheme makes the techno-economic optimization of the PV systems mainly based on the self-consumption. The calculation of this parameter involves hourly building loads and hourly PV generation. LÄS MER

  3. 12. Genome-wide association studies using machine learning

    Kandidat-uppsats, Umeå universitet/Institutionen för datavetenskap

    Författare :Mohammad Mshaleh; [2022]
    Nyckelord :;

    Sammanfattning : Genom-Wide Association Study (GWAS) is a field that studies the genomics of organisms. GWAS focuses on what is called single nucleotide polymorphisms (SNP). In GWAS,the data of the SNPs is usually massive, which requires modern statistical analysis methods to investigate the relationship between those SNPs and a phenotype. LÄS MER

  4. 13. Price Prediction for Used Cars : A Comparison of Machine Learning Regression Models

    Kandidat-uppsats, Mittuniversitetet/Institutionen för informationssystem och –teknologi

    Författare :Marcus Collard; [2022]
    Nyckelord :Machine Learning; Price Prediction; Used Cars; Regression Analysis; Depreciation;

    Sammanfattning : Bilar av ett visst märke, modell, år och uppsättning funktioner börjar med ett pris som fastställs av tillverkaren. När de åldras och säljs vidare som de används, är de föremål för prissättning av utbud och efterfrågan för deras speciella uppsättning funktioner, utöver deras unika historia. LÄS MER

  5. 14. Towards Understanding slag build-up in a Grate-Kiln furnace : A study of what parameters in the Grate-Kiln furnace leads to increased slag build-up, in a modern pellet production kiln

    Master-uppsats, Linköpings universitet/Institutionen för datavetenskap

    Författare :Oscar Olsson; Uno Österman; [2022]
    Nyckelord :Grate-kiln; Slag; Interpretable machine learning; IID; independent and identically distributed; Kulsinter; pellets; slagg; slag; LKAB;

    Sammanfattning : As more data is being gathered in industrial production facilities, the interest in applying machine learning models to the data is growing. This includes the iron ore mining industry, and in particular the build-up of slag in grate-kiln furnaces. LÄS MER
