  1. 1. Spatial modeling with INLA for analysis of unequal care in Skåne

    Kandidat-uppsats, Lunds universitet/Matematisk statistik

    Författare :Julia Wierzchoslawska; [2023]
    Nyckelord :Mathematics and Statistics;

    Sammanfattning : The objective of this thesis is to extend on a previous analysis of health care accessibility for patients diagnosed with a chronic disease in Region Skåne. The previous analysis resulted in a logistic mixed effects model having municipality as a random effect and age as a first-degree spline-function. LÄS MER

  3. 2. A regression spline based approach to enhance the prediction accuracy of bicycle counter data

    Magister-uppsats, Malmö universitet/Institutionen för datavetenskap och medieteknik (DVMT)

    Författare :Omar Alkayali; [2022]
    Nyckelord :Bicycle counter; regression spline; trend curve; prediction; ensemble method;

    Sammanfattning : Regression analysis has been used in previous research to predict the number of bicycles registered by a bicycle counter. An important step to improve the prediction is to include a long-term trend curve estimate as part of the formulation of the regression target variable. LÄS MER

  4. 3. State Estimation Using a Parametric Approximation of the Viterbi Algorithm

    Master-uppsats, Linköpings universitet/Institutionen för systemteknik

    Författare :Åslund Jakob; [2021]
    Nyckelord :State estimation; Viterbi algorithm;

    Sammanfattning : In this work, a new method of approximating the Maximum-likelihood estimate has been presented. The method consists of first using the Viterbi algorithm to estimate the log likelihood of the state, and then approximating that log likelihood to keep the computational complexity down. LÄS MER

  5. 4. Combining scientific computing and machine learning techniques to model longitudinal outcomes in clinical trials.

    Master-uppsats, Linköpings universitet/Institutionen för datavetenskap

    Författare :Harshavardhan Subramanian; [2021]
    Nyckelord :Bootstrap sampling; Cubic spline interpolation; Sparse regression; SINDy; Bayesian inference; Mechanistic Modeling; Scientific computing;

    Sammanfattning : Scientific machine learning (SciML) is a new branch of AI research at the edge of scientific computing (Sci) and machine learning (ML). It deals with efficient amalgamation of data-driven algorithms along with scientific computing to discover the dynamics of the time-evolving process. LÄS MER

  7. 5. Automatic Projector Calibration for Curved Surfaces Using an Omnidirectional Camera

    Master-uppsats, KTH/Optimeringslära och systemteori

    Författare :David Tennander; [2017]
    Nyckelord :;

    Sammanfattning : This master’s thesis presents one approach to remove distortions generated by projecting onto non flat surfaces. By using an omnidirectional camera a full 360 dome could be calibrated and the corresponding angles between multiple projections could be calculated. LÄS MER
