16. Modelling rare events using non-parametric machine learning classifiers - Under what circumstances are support vector machines preferable to conventional parametric classifiers?
Kandidat-uppsats, Göteborgs universitet/Institutionen för nationalekonomi med statistikSammanfattning : Rare event modelling is an important topic in quantitative social science research. However, despite the fact that traditional classifiers 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.

17. Association between cognitive measures, global brain surface area, genetics, and screen-time in young adolescents : Estimation of causal inference with machine learning
Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)Sammanfattning : 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. LÄS MER
18. Kognitivt tillgänglig undervisning i samhällskunskap : En forskningsöversikt med implikationer för inkluderande praktik i helklass
Uppsats för yrkesexamina på avancerad nivå, Stockholms universitet/Institutionen för de humanistiska och samhällsvetenskapliga ämnenas didaktikSammanfattning : Denna forskningsöversikt syftade till att undersöka vad som kan utgöra kognitiva hinder i lärandeprocessen under samhällskunskapsundervisning, med målet att finna implikationer för undervisning och examinationsformer som kan nå och engagera fler elever. Arbetet utgick ifrån ett teoretiskt ramverk för universellt utformade lärandesituationer, för att bidra till proaktiv och preventiv planering utifrån elevers funktionsvariation. LÄS MER
19. Spatial modelling of sustainable wind power development
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : Measures to mitigate climate change has never been a more pressing matter thanit is today and the global debate over energy security, environmental decline andlimited resources is heated, which motivates decision makers and leaders to searchfor alternative energy sources, renewable sources. The Swedish government has seta goal to make its entire domestic electricity production 100 % renewable and phaseout energy production based on fossil fuels entirely by year 2040, where wind powerwill contribute largely to that goal.

20. General Attitudes and Mode Choice : A mode choice study in Stockholm using Schwartz value-items grouped by personal characteristics
Master-uppsats, KTH/Transport och systemanalysSammanfattning : Value-items from the Schwartz scale of Values have been added to travel data to investigate if the value-items can be used to model mode choice. Two kinds of mode choice models, both discrete choice models, multinomial models (MNL) and the Machine Learning Models Random Forests (RF) were constructed, using Travel Diary data (RVU) and additional data from European Social Survey (ESS).
