1. 1. Monte Carlo Localization with Hilbert maps as Likelihood Fields

   Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

   Författare :ALEXANDER WALLÉN KIESSLING; [2023]
   Nyckelord :Localization; Monte Carlo; Mapping; Hilbert maps; Observation Likelihood model.; Lokalisering; Monte Carlo; Kartläggning; Hilbert kartor; Sensor modell.;

   Sammanfattning : This work focuses on using sparse Hilbert maps as continuous likelihood field observation models, instead of utilizing traditional beam observation models. This observation model is integrated with a Monte Carlo Localization scheme, and localization is simulated in randomly generated 2D mazes. LÄS MER

3. 2. Kan en lätt knuff få människor att fimpa rätt? - En kvalitativ observations- och intervjustudie om hur invånare i Göteborg förhåller sig till Göteborgs Stads kampanj Fimpologi

   Kandidat-uppsats, Göteborgs universitet/Institutionen för journalistik, medier och kommunikation

   Författare :Vera Ebbesson Dehlin; Adam Karseland; [2022-01-05]
   Nyckelord :Kampanj; fimpar; rökning; beteende; nudging; Elaboration Likelihood Model; observation;

   Sammanfattning : Syfte: Syftet med studien är att undersöka hur invånare i Göteborg tar till sig av kommunikationsbudskap som syftar till att förändra ett specifikt beteende. Studien kommer specifikt att undersöka hur människor som befinner sig på utvalda hållplatser i Göteborg förhåller sig till Göteborgs Stads kampanj “Fimpologi”. LÄS MER

4. 3. A comparative evaluation of machine learning models for engagement classification during presentations : A comparison of distance- and non-distance-based machine learning models for presentation classification and class likelihood estimation

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Rebwar Ali Omer Bajallan; [2022]
   Nyckelord :Audience engagement; Engagement quantification; Machine learning; Distance-based models; Few-shot learning; Statistical analysis; Publiksengagemang; Engagemangskvantifiering; Maskininlärning; Distansbaserade modeller; Few-shot inlärning; Statistisk analys;

   Sammanfattning : In recent years, there has been a significant increase in the usage of audience engagement platforms, which have allowed for engaging interactions between presenters and their audiences. The increased popularity of the platforms comes from the fact that engaging and interactive presentations have been shown to improve learning outcomes and create positive presentation experiences.

5. 4. Jump Estimation of Hidden Markov Models with Time-Varying Transition Probabilities

   Kandidat-uppsats, Lunds universitet/Matematisk statistik

   Författare :Henning Tansjö; [2020]
   Nyckelord :Jump estimation; Hidden Markov model; financial time series; clustering; unsupervised learning.; Mathematics and Statistics;

   Sammanfattning : The Hidden Markov model is applicable to a wide variety of fields. Applied to financial time series, its assumed underlying state sequence can reflect the time series' tendency to behave differently over different periods of time. In many situations, models could be improved by including exogenous data. LÄS MER

7. 5. Doubly Charged Higgs Signal with Same-Sign Tau-inclusive Dilepton Final States

   Magister-uppsats, Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

   Författare :Simon Arnling Bååth; [2018]
   Nyckelord :ATLAS; same-sign; dilepton; higgs; LHC; signal sample; Physics and Astronomy;

   Sammanfattning : Abstract The current Standard Model of particle physics contains few interactions resulting in a final state with two leptons with the same charge. Any observation of an excess of such same-sign dileptons would be an indication of new physics processes, making it a useful channel when searching for exotic physics. LÄS MER
