11	Naive semi-supervised deep learning med sammansättning av pseudo-klassificerare / Naive semi-supervised deep learning with an ensemble of pseudo-labelers Karlsson, Erik, Nordhammar, Gilbert January 2019 (has links) Ett vanligt problem inom supervised learning är brist på taggad träningsdata. Naive semi-supervised deep learning är en träningsteknik som ämnar att mildra detta problem genom att generera pseudo-taggad data och därefter låta ett neuralt nätverk träna på denna samt en mindre mängd taggad data. Detta arbete undersöker om denna teknik kan förbättras genom användandet av röstning. Flera neurala nätverk tränas genom den framtagna tekniken, naive semi-supervised deep learning eller supervised learning och deras träffsäkerhet utvärderas därefter. Resultaten visade nästan enbart försämringar då röstning användes. Dock verkar inte förutsättningarna för röstning ha varit särskilt goda, vilket gör det svårt att dra en säker slutsats kring effekterna av röstning. Även om röstning inte gav förbättringar har NSSDL visat sig vara mycket effektiv. Det finns flera applikationsområden där tekniken i framtiden skulle kunna användas med goda resultat.

12	Medias makt : Hur "media salience" påverkade valdeltagandet i Sverige under riksdagsvalet 2018 Gustafsson, Wimar January 2023 (has links) The political interest of an individual has always been a factor in theindividual’s decision to vote in an election or not. But is it only theindividuals own interest that decides if they participate in the election, or arethey affected by what media they consume and how the media frames theissues? The dominant explanation for if individuals decide to participate inelections are rooted in a couple of different factors, their socioeconomicalsituation, and their cultural background, but this essay focuses on how mediaaffects individuals voting behaviour. Other studies have looked at how mediaexposure affects individuals’ participation. They found that media exposurehas a positive effect on the individual’s likelihood of participating ininstitutional political situations. This essay uses data from SOM-institute toanalyse how media consumption affects the individual’s likelihood toparticipate in the national election. The results show that media consumptioninfluences the individuals decision to vote however, the extent of mediaconsumed does not matter for participation as expected as it also could havea negative effect on participation. The other part of the result is that thesource of the media is not important to if it increases the individuals’ interestin politics. This indicates that for the individual the extent of mediaconsumed and from what source, does not have a major effect on their votingbehaviour. Media Salience Media konsumtion Röstning Politiskt intresse Salience Prominence Uppmärksamhet Röstningsbeteende
13	Portraits of Participation : An interview study on the effects of social learning theory mechanisms on political participation Olsson, Jakob January 2023 (has links) If democratic society is to avert the dire straits that may come from decreasing levels of political participation and civic engagement, all potential explanatory factors must be explored. The purpose of this paper is to i) elucidate how the modeling and self-efficacy mechanisms of social learning theory affect individuals’ decisions to participate politically or not, and ii) assess the applicability of the relatively unutilized social learning theory in studies on political socialization and participation, respectively. By conducting a study composed of life history interviews, the paper aims to contribute to the research field by providing new explanations on how and why participatory behavior occurs in individuals, potentially filling a research gap by using and developing the previously unutilized social learning theory. The study finds that the proposed social learning theory mechanisms appear to have some explanatory power in the context of individuals’ political participation and asserts that social learning theory may very well be applicable in similar future studies as a complement to other explanatory factors.
