  1. 1. 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.

  3. 2. The Tower: Design of Distinct AI Personalities in Stealth-Based Games Modeling personalities with believable and consistent behaviour for NPCs in games using stealth gameplay style

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

    Author : Marek Cernák; Lianoudakis Orestis; [2021-03-03]
    Keywords : stealth gameplay; games research; AI; NPC; autonomous agents; personality modeling; thesis;

    Abstract : Computer games using stealth situations for defining their gameplay often rely onmodeling an immersive, yet exploitable non-player character behaviour. Traditionally, the aim of the design of such a behaviour is to provide players with memorablebehaviour patterns of the in-game agents in order to facilitate the means of devisingstrategies used by players to finish the game levels.

  4. 3. Option Modelling by Deep Learning

    University essay from Göteborgs universitet/Institutionen för nationalekonomi med statistik

    Author : Niclas Klausson; Victor Tisell; [2021-02-10]
    Keywords : Deep learning; deep hedging; generative adversial networks; arbitrage pricing;

    Abstract : In this thesis we aim to provide a fully data driven approach for modelling financial derivatives, exclusively using deep learning. In order for a derivatives model to be plausible, it should adhere to the principle of no-arbitrage which has profound consequences on both pricing and risk management. READ MORE

  5. 4. Search for Higgs-like bosons through optimization of top-quark modelling

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

    Author : Rafael Antonio Lopez; [2021]
    Keywords : ttbar; top quark modelling; BSM; 2HDM S; Higgs-like bosons; ATLAS; HWW; XSh; top estimation; top remodelling; Physics and Astronomy;

    Abstract : Accurate estimations of background processes associated with top-quarks are vital to studies concerned with finding new physics at the Large Hadron Collider (LHC)at CERN. Search for Higgs-like bosons in the ATLAS experiment at LHC was performed by optimising the use of b-jet tagging algorithms and improving on tt backgroundmodelling. READ MORE

  6. 5. Association between cognitive measures, global brain surface area, genetics, and screen-time in young adolescents : Estimation of causal inference with machine learning

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Evgenija Kravchenko; [2021]
    Keywords : Causal modelling; DirectLiNGAM; PGS; intelligence; screen time; cognitive development; Kausal modellering; DirectLiNGAM; PGS; intelligens; skärmtid; kognitiv utveckling;

    Abstract : Screen media activity such as watching TV and videos, playing video games, and using social media has become a popular leisure activity for children and adolescents. The effect of screen time has been a highly debated topic; however, there is still very little known about it. READ MORE
