  3. 2. Bayesian inference in aggregated hidden Markov models

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Emil Marklund; [2015]
    Nyckelord :Bayesian inference; aggregated hidden Markov models; model selection; variational Bayes; nested sampling; single molecule data;

    Sammanfattning : Single molecule experiments study the kinetics of molecular biological systems. Many such studies generate data that can be described by aggregated hidden Markov models, whereby there is a need of doing inference on such data and models. LÄS MER

  4. 3. Wearable Sensor Data Fusion for Human Stress Estimation

    Master-uppsats, Linköpings universitet/Reglerteknik

    Författare :Simon Ollander; [2015]
    Nyckelord :stress; data fusion; classification; modelling; wearables; physiological sensors;

    Sammanfattning : With the purpose of classifying and modelling stress, different sensors, signal features, machine learning methods, and stress experiments have been compared. Two databases have been studied: the MIT driver stress database and a new experimental database, where three stress tasks have been performed for 9 subjects: the Trier Social Stress Test, the Socially Evaluated Cold Pressor Test and the d2 test, of which the latter is not classically used for generating stress.

  5. 4. OLLDA: Dynamic and Scalable Topic Modelling for Twitter : AN ONLINE SUPERVISED LATENT DIRICHLET ALLOCATION ALGORITHM

    Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Författare :Shatha Jaradat; [2015]
    Nyckelord :Latent Dirichlet Allocation; Labeled Latent Dirichlet Allocation; online Variational Bayes for LDA; multi-labeled; supervised; Twitter; recommendations; variational inference.; Latent Dirichlet Allocation; Labeled Latent Dirichlet Allocation; online Variational Bayes for LDA; multi-labeled; supervised; Twitter; recommendations; variational inference.;

    Sammanfattning : Providing high quality of topics inference in today's large and dynamic corpora, such as Twitter, is a challenging task. This is especially challenging taking into account that the content in this environment contains short texts and many abbreviations. LÄS MER

  7. 5. Online inference of topics : Implementation of the topic model Latent Dirichlet Allocation using an online variational bayes inference algorithm to sort news articles

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Kim Wedenberg; Alexander Sjöberg; [2014]
    Nyckelord :;

    Sammanfattning : The client of the project has problems with complex queries and noisewhen querying their stream of five million news articles per day. Thisresults in much manual work when sorting and pruning the search result of their query. LÄS MER
