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

   University essay from Linnéuniversitetet/Institutionen för datavetenskap och medieteknik (DM)

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

   Abstract : 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. READ MORE

3. 2. A Markovian Approach to Financial Market Forecasting

4. 3. Predicting Short-term Absences of a Railway Crew using Historical Data

   University essay from KTH/Matematisk statistik

   Author : Agnes Björnfot; Sandra Fjelkestam; [2023]
   Keywords : statistics; machine learning; absence prediction; random forest; XGBoost; quantile regression; statistik; maskininlärning; frånvaroprognoser; random forest; XGBoost; kvantilregression;

   Abstract : Transportation via train is considered the most environmentally friendly way of traveling and is widely seen as the future of transportation. Canceled and delayed trains worsen customer satisfaction; thus, punctual trains are crucial for railway companies. READ MORE

5. 4. Impact of different primary particles on Geant4 simulation execution time - study on protons and pions

   University essay from Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

   Author : Rebecca Jigström Madeira; [2021]
   Keywords : Geant4; Monte Carlo method; Large Hadron Collider; simulation time; collider experiment; Physics and Astronomy;

   Abstract : The High Luminosity Large Hadron Collider (HL-LHC) at CERN, an improvement to the LHC, scheduled to be operating in 2027, will further the potential for scientific breakthroughs in High Energy Physics. The project’s demand in computational resources, however, is predicted to exceed what will be available then. READ MORE

6. 5. Purchase Probability Prediction : Predicting likelihood of a new customer returning for a second purchase using machine learning methods

   University essay from Umeå universitet/Institutionen för matematik och matematisk statistik

   Author : Olivia Alstermark; Evangelina Stolt; [2021]
   Keywords : Purchase Probability Prediction; Machine Learning Models; Well-Calibrated Probabilities; Imbalanced Data; Data Protection;

   Abstract : When a company evaluates a customer for being a potential prospect, one of the key questions to answer is whether the customer will generate profit in the long run. A possible step to answer this question is to predict the likelihood of the customer returning to the company again after the initial purchase. READ MORE
