5. 4. MetaStackVis: Visually-Assisted Performance Evaluation of Metamodels in Stacking Ensemble Learning

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

   Författare :Ilya Ploshchik; [2023]
   Nyckelord :Visualization; interaction; metamodels; validation metrics; predicted probabilities; stacking; stacked generalization; ensemble learning; machine learning;

   Sammanfattning : Stacking, also known as stacked generalization, is a method of ensemble learning where multiple base models are trained on the same dataset, and their predictions are used as input for one or more metamodels in an extra layer. This technique can lead to improved performance compared to single layer ensembles, but often requires a time-consuming trial-and-error process. LÄS MER

7. 5. Evaluation of the challenges and opportunities of Vehicle-to-Grid technology and the potential revenue streams for BEV fleet owners and aggregators

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

   Författare :Lukas Strandberg; Madeleine Sandberg; [2023]
   Nyckelord :Vehicle-to-Grid; Grid flexibility; Capacity markets; Barriers; Fordon-till-nätteknologi; Elnätsflexibilitet; Kapacitetsmarknader; Barriärer;

   Sammanfattning : The increasing amount of renewable energy being connected to the power grid, and the intermittent nature of these resources, calls for increased grid flexibility to ensure operational safety and stability. An effective solution to address this need could be through wider implementation of various energy storage technologies. LÄS MER
