  1. 1. Evaluating Bag Of Little Bootstraps On Logistic Regression With Unbalanced Data

    University essay from Uppsala universitet/Statistiska institutionen

    Author : Henrik Bark; [2023]
    Keywords : Bootstrapping; Logistic Regression; Bag of Little Bootstraps; BLB; Penalized Maximum Likelihood Estimation; PMLE;

    Abstract : The Bag of Little Bootstraps (BLB) was introduced to make the bootstrap method more computationally efficient when used on massive data samples. Since its introduction, a broad spectrum of research on the application of the BLB has been made. READ MORE

  3. 2. Using forest reflectance modelling to estimate albedo for narrow-view satellites

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap; Lunds universitet/Fysiska institutionen

    Author : Nick Bergmans; [2023]
    Keywords : satellite; remote sensing; albedo; surface reflectance; vegetation; forest; machine learning; albedo estimation; Earth and Environmental Sciences;

    Abstract : Surface albedo estimations from remote sensing are invaluable for energy balance descrip- tions in climate research. The aim of this work is to evaluate the possibility of using Sentinel-2 satellite data to get the total albedo of a small, vegetated area. READ MORE

  4. 3. Blind Acoustic Feedback Cancellation for an AUV

    University essay from Linköpings universitet/Reglerteknik

    Author : Hampus Frick; [2023]
    Keywords : acoustical feedback; adaptive filter; least leaky mean square; Kalman; blind source separation; independent component analysis; complex independent component analysis; degenerative unmixing estimation technique; convolutive mixture;

    Abstract : SAAB has developed an autonomous underwater vehicle that can mimic a conventional submarine for military fleets to exercise anti-submarine warfare. The AUV actively emits amplified versions of received sonar pulses to create the illusion of being a larger object. READ MORE

  5. 4. Towards Deep Learning Accelerated Sparse Bayesian Frequency Estimation

    University essay from Lunds universitet/Matematisk statistik

    Author : Mika Persson; [2022]
    Keywords : Bayesian Statistics; Deep Learning; Frequency Estimation; Generative Adversarial Networks; Artificial Neural Networks; Statistical Modelling; Mathematics and Statistics;

    Abstract : The Discrete Fourier Transform is the simplest way to obtain the spectrum of a discrete complex signal. This thesis concerns the case when the signal is known to contain a small (unknown) number of frequencies, not limited to the discrete Fourier frequencies, embedded in complex Gaussian noise.

  6. 5. Short-term O&M Planning for Offshore Wind Energy

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Miguel de Matos e Sá; [2022]
    Keywords : Offshore wind energy; O M scheduling; optimization; wake effect; weather forecasts; risk analysis; Portugal; WindFloat Atlantic; Havsbaserad vindkraft; planering av drift och underhåll; optimering; wake effect; väderprognoser; riskanalys; Portugal; WindFloat Atlantic;

    Abstract : Significant breakthroughs are currently being achieved for Offshore Wind Energy (OWE), as offshore wind turbines are moving further away from the shore, benefitting from as vaster wind resource availability. On the other hand, the current trends of the OWE industry make new challenges arise. READ MORE
