  1. 1. Application of Fourier Transforms to time-resolved ambient pressure spectroscopy operando studies of CO oxidation over Pt(111)

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Synkrotronljusfysik

    Author : Grigore-Leon Ratiu; [2024]
    Keywords : Physics and Astronomy;

    Abstract : The study of heterogeneous catalysis has important implications in increasing the efficiency of industrial processes and in reducing the emissions of greenhouse gases from sources such as automobiles. A reaction with high industrial relevance is the oxidation of CO on noble metal catalysts. READ MORE

  2. 2. Image Quality Assessment Pipeline and Semi-Automated Annotation method for Synthetic Data

    University essay from Göteborgs universitet/Institutionen för data- och informationsteknik

    Author : Liam Le Tran; Edina Dedovic; [2023-10-24]
    Keywords : Facial Expression Recognition; FACS; Action Units; styleGAN2-ada; synthetic data; Image Quality Assessment; Multi-stage Pre-training; Pipeline Processing; Semi-automated Human Annotation;

    Abstract : Predicting human emotions through facial expression, particularly in relation to medication field such as clinical trial settings, has garnered scientific interest in recent years due to significant understanding of the impact of treatment on emotions and social functioning. This thesis aims to improve performance of a FER model using large scale of synthetic data. READ MORE

  3. 3. Point process learning for non-parametric intensity estimation with focus on Voronoi estimation

    University essay from Göteborgs universitet/Institutionen för matematiska vetenskaper

    Author : Alexander Thorén; [2023-03-28]
    Keywords : ;

    Abstract : Point process learning is a new statistical theory that gives us a way to estimate parameters using cross-validation for point processes. By thinning a point pattern we are able to create training and validation sets which are then used in prediction errors. READ MORE

  4. 4. 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

  5. 5. Wi-Fi fingerprinting as a mean to measure building occupancy : A case study in an office environment

    University essay from KTH/Transportplanering

    Author : Johan Bexhorn; Karl Kvarnefalk; [2023]
    Keywords : Wi-Fi tracking systems; Wi-Fi fingerprinting; footfall analytics;

    Abstract : The task of collecting visitor data in an indoor environment and therein determining the occupancy of a building is an extensive task. Conventional methods are expensive, time-consuming, and often lack the ability to produce data in longer time series. Further, they often require disruption of the studied area as equipment must be deployed. READ MORE
