  1. 16. 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

  3. 17. Driving Behavior Prediction by Training a Hidden Markov Model

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

    Författare :Anna Wilhelmsson; Sofia Bedoire; [2020]
    Nyckelord :Human behavior prediction; Hidden MarkovModel; aggressive behavior; non-aggressive behavior; Viterbidecoding algorithm; Baum Welch training; Viterbi training;

    Sammanfattning : Introducing automated vehicles in to traffic withhuman drivers, human behavior prediction is essential to obtainoperation safety. In this study, a human behavior estimationmodel has been developed. The estimations are based on aHidden Markov Model (HMM) using observations to determinethe driving style of surrounding vehicles.

  4. 18. Automatic Speech Recognition in Somali

    Master-uppsats, Linköpings universitet/Statistik och maskininlärning

    Författare :Naveen Gabriel; [2020]
    Nyckelord :automatic speech recognition; speaker adaptation; generative training; gaussian mixture model; kaldi; finite-state transducers;

    Sammanfattning : The field of speech recognition during the last decade has left the research stage and found its way into the public market, and today, speech recognition software is ubiquitous around us. An automatic speech recognizer understands human speech and represents it as text. LÄS MER

  5. 19. Map Matching to road segments using Hidden Markov Model with GNSS, Odometer and Gyroscope

    Master-uppsats, Linköpings universitet/Programvara och system

    Författare :Hugo Lindholm; [2019]
    Nyckelord :map matching; hmm; hidden markov model; gnss;

    Sammanfattning : In this thesis the Hidden Markov Model (HMM) is used in the process of map matching to investigate the accuracy for road segment map matching. A few HMM algorithms using a Global Navigation Satellite System (GNSS) receiver, odometer and gyroscope sensors are presented. The HMM algorithms are evaluated on four accuracy metrics. LÄS MER

  7. 20. HMMs and LSTMs for On-line Gesture Recognition on the Stylaero Board : Evaluating and Comparing Two Methods

    Master-uppsats, Linköpings universitet/Artificiell intelligens och integrerade datorsystem

    Författare :Sebastian Sibelius Parmbäck; [2019]
    Nyckelord :HMM; LSTM; AI; GR; ML; ANN; Hidden Markov Model; Long Short Term Memory; Gesture Recognition; Machine Learning; Artificial Neural Network;

    Sammanfattning : In this thesis, methods of implementing an online gesture recognition system for the novel Stylaero Board device are investigated. Two methods are evaluated - one based on LSTMs and one based on HMMs - on three kinds of gestures: Tap, circle, and flick motions. LÄS MER
