  1. 1. Driver Behavior Classification in Electric Vehicles

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

    Author : FEDERICA COMUNI; CHRISTOPHER MÉSZÁROS; [2021-07-06]
    Keywords : Aggressive driver behavior; Driver behavior classification; Self-attention; Recurrence plots; active learning; Active deep dropout; Gradual pseudo labeling;

    Abstract : Studies have shown that driving style affects the energy consumption of electric vehicles, with aggressive driving consuming up to 30% more energy than moderate driving. Therefore, modeling of aggressive driving can provide a more precise estimation of the energy consumption and the remaining range of a vehicle. READ MORE

  4. 3. Principal Component Analysis and the Cross-Sectional Variation of Returns

    University essay from

    Author : Armin Ramovic; Mikael Åkerman; [2021-06-23]
    Keywords : Principal Component Analysis; PCA; principal components; cross-sectional variation of returns; risk premia; asset pricing; demensionality reduction; risk factors; machine learning;

    Abstract : We utilize Principal Component Analysis (PCA), a dimensionality reduction technique, on a set of 142 risk factors, including macroeconomic factors, proposed in financial literature to construct factor models with high explanatory powers when analysing the cross-sectional variation of portfolio returns. We apply a Fama and Macbeth (1973) two-pass regression to estimate risk premia commanded by our principal components. READ MORE

  5. 4. Modelling rare events using non-parametric machine learning classiers - Under what circumstances are support vector machines preferable to conventional parametric classiers?

    University essay from Göteborgs universitet/Institutionen för nationalekonomi med statistik

    Author : Lukas Ma; [2021-04-06]
    Keywords : ;

    Abstract : Rare event modelling is an important topic in quantitative social science research. However, despite the fact that traditional classiers based upon general linear models (GLM) might lead to biased results, little attention in the social science community is devoted to methodological studies aimed at alleviating such bias, even fewer of them have considered the use of machine learning methods to tackle analytical problems imposed by rare events.

  6. 5. Application of Machine Learning Algorithms for Post Processing of Reference Sensors

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

    Author : VASILIKI LAMPROUSI; [2021-04-01]
    Keywords : Object detection; machine learning; camera; sensors; semi-supervised learning;

    Abstract : The Autonomous Drive (AD) systems and Advanced Driver Assistance Systems(ADAS) in the current and future generations of vehicles include a large numberof sensors which are used to perceive the vehicle’s surroundings. The productionsensors of these vehicles are verified and validated against reference data that areoriginated from high-accurate reference sensors that are placed in a reference roofbox at the top of the vehicle.
