  1. 1. Sum-Product Network in the context of missing data

    Master-uppsats, KTH/Matematisk statistik

    Författare :Pierre Clavier; [2020]
    Nyckelord :Statistics; Mixture model; Probabilistic Graphical Models; Statistik; Probabilistiska grafiska modeller;

    Sammanfattning : In recent years, the interest in new Deep Learning methods has increased considerably due to their robustness and applications in many fields. However, the lack of interpretability of these models and the lack of theoretical knowledge about them raises many issues. It is in this context that sum product network models have emerged. LÄS MER

  2. 2. Sequential analyses in psychological research using Bayesian statistics

    Magister-uppsats, Lunds universitet/Institutionen för psykologi

    Författare :Pierre Klintefors; [2019]
    Nyckelord :Sequential analysis; Bayesian statistics; Optional stopping; Bayes factor; Bayesian estimation; Highest Density Intervals; Social Sciences;

    Sammanfattning : It is important in psychological research to use well planned methods that are as time and resource efficient as possible, without jeopardizing the reliability and validity of psychological science. The present paper aims to test how sequential analyses could be implemented in psychological research using Bayesian statistics. LÄS MER

  3. 3. An application of Bayesian Hidden Markov Models to explore traffic flow conditions in an urban area

    Master-uppsats, Uppsala universitet/Statistiska institutionen

    Författare :Lovisa Andersson; [2019]
    Nyckelord :Bayesian statistics; hidden states; Markov chain; traffic flow modeling; filtering; smoothing; most probable state sequence; MCMC; Hamiltonian Monte Carlo; No-U-Turn sampler;

    Sammanfattning : This study employs Bayesian Hidden Markov Models as method to explore vehicle traffic flow conditions in an urban area in Stockholm, based on sensor data from separate road positions. Inter-arrival times are used as the observed sequences. LÄS MER

  4. 4. Forecasting Election Results: A Bayesian Frequentist Comparison

    Kandidat-uppsats, Lunds universitet/Statistiska institutionen

    Författare :Oldehed Erik; [2019]
    Nyckelord :Bayesian forecasting; frequentist forecasting; non-homogeneous hidden Markov models; autoregression; kernel smoothing; Mathematics and Statistics;

    Sammanfattning : We present a Bayesian and frequentist comparison when forecasting elections through polls. Our focus is on studying the differences of these approaches in forecasting elections. An evaluation of the fit is performed using the odds ratio. LÄS MER

  5. 5. Classification of Wi-Fi Sensor Data for a Smarter City : Probabilistic Classification using Bayesian Statistics

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för matematik och matematisk statistik; Umeå universitet/Institutionen för matematik och matematisk statistik

    Författare :Elin Tyni; Johanna Wikberg; [2019]
    Nyckelord :;

    Sammanfattning : As cities are growing with an increasing number of residents, problems with the traffic such as congestion and larger emission arise. The city planners have challenges with making it as easy as possible for the residents to commute and in as large scale as possible to avoid vehicles. LÄS MER
