  1. 1. Regularization Methods and High Dimensional Data: A Comparative Study Based on Frequentist and Bayesian Methods

    University essay from Lunds universitet/Statistiska institutionen

    Author : Markus Gerholm; Johan Sörstadius; [2024]
    Keywords : Linear regression; high dimensional data; regularization; Bayesian methods; Mathematics and Statistics;

    Abstract : As the amount of high dimensional data becomes increasingly accessible and common, the need for reliable methods to combat problems such as overfitting and multicollinearity increases. Models need to be able to manage large data sets where predictor variables often outnumber the amount of observations. READ MORE

  2. 2. Point process learning for non-parametric intensity estimation with focus on Voronoi estimation

    University essay from Göteborgs universitet/Institutionen för matematiska vetenskaper

    Author : Alexander Thorén; [2023-03-28]
    Keywords : ;

    Abstract : Point process learning is a new statistical theory that gives us a way to estimate parameters using cross-validation for point processes. By thinning a point pattern we are able to create training and validation sets which are then used in prediction errors. READ MORE

  3. 3. Robust Aircraft Positioning using Signals of Opportunity with Direction of Arrival

    University essay from Linköpings universitet/Reglerteknik

    Author : Erik Axelsson; Sebastian Fagerstedt; [2023]
    Keywords : Simultaneous localisation and mapping; direction of arrival; signals of opportunity; extended Kalman filter; positioning;

    Abstract : This thesis considers the problem of using signals of opportunity (SOO) with known direction of arrival (DOA) for aircraft positioning. SOO is a collective name for a wide range of signals not intended for navigation but which can be intercepted by the radar warning system on an aircraft. READ MORE

  4. 4. Fysisk aktivitet hos hundägare och hundar som deltar i ett gemensamt träningsprogram : förändring av fysisk aktivitetsgrad samt samband mellan uppmätta och skattade värden

    University essay from SLU/Dept. of Clinical Sciences; SLU/Dept. of Anatomy, Physiology and Biochemistry

    Author : Ida Bergvall; Louise Wallander; [2023]
    Keywords : accelerometer; ”fysisk aktivitet”; ”gemensamt träningsprogram”; hund; hundägare; hälsa; självskattning; träning;

    Abstract : En alltmer stillasittande livsstil ses i dagens samhälle, vilket leder till negativa hälsoeffekter hos både människa och hund. Till följd av detta ses även en ökad mortalitet och metoder för att öka den fysiska aktiviteten hos människa och hund behöver därför implementeras. READ MORE

  5. 5. Machine Learning for State Estimation in Fighter Aircraft

    University essay from KTH/Optimeringslära och systemteori

    Author : Axel Boivie; [2023]
    Keywords : State estimation; machine learning; fighter aircraft; neural networks; long short- term memory; LSTM; sensor fusion; air data system; ADS.; Tillståndsestimering; maskininlärning; stridsflygplan; neurala nätverk; sensorfusion; luftdatasystem.;

    Abstract : This thesis presents an estimator to assist or replace a fighter aircraft’s air datasystem (ADS). The estimator is based on machine learning and LSTM neuralnetworks and uses the statistical correlation between states to estimate the angleof attack, angle of sideslip and Mach number using only the internal sensorsof the aircraft.
