  1. 16. A small sample study of some sandwich estimators to handle heteroscedasticity

    University essay from Uppsala universitet/Statistiska institutionen

    Author : Viking Westman; [2021]
    Keywords : ;

    Abstract : This simulation study sets out to investigate Heteroscedasticity-Consistent Covariance Matrix Estimation using the sandwich method in relatively small sample sizes. The different estimators are evaluated on how accurately they assign confidence intervals around a fixed, true coefficient, in the presence of random sampling and both homo- and heteroscedasticity.

  3. 17. Random projections in a distributed environment for privacy-preserved deep learning

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

    Author : Malcolm Bagger Toräng; [2021]
    Keywords : Random projections; Generative adversarial networks; Privacy metrics; Deep learning; Obfuscation.; Slumpmässiga projektioner; Generativa kontroversiella nätverk; Privatiserings-mått; Djupinlärning; Obfuskering.;

    Abstract : The field of Deep Learning (DL) only over the last decade has proven useful for increasingly more complex Machine Learning tasks and data, a notable milestone being generative models achieving facial synthesis indistinguishable from real faces. With the increased complexity in DL architecture and training data, follows a steep increase in time and hardware resources required for the training task. READ MORE

  4. 18. Density Matrix Simulation of Quantum Error Correction

    University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Author : Arvid Rolander; [2020]
    Keywords : quantum error Correction; density matrix simulation; Steane code; Physics and Astronomy;

    Abstract : Quantum error correction will be integral in developing full scale quantum computers, but as of yet beneficial quantum error correction has not been demonstrated experimentally. An important question is therefore what prerequisites need to be met to achieve this. READ MORE

  5. 19. Comparison of Control Approaches for Formation Flying of Two Identical Satellites in Low Earth Orbit

    University essay from KTH/Rymdteknik

    Author : Hasan Basaran; [2020]
    Keywords : Aerospace; Chief; Control; Deputy; Feedback Linearization; Follower; Formation Flight; Fuel Consumption; Guidance; Leader; Model Predictive Control; Relative Orbit; Rendezvous; Sliding Mode.;

    Abstract : Formation flying of satellites describes a mission in which a set of satellites arrange their position with respect to one another. In this paper, satellite formation flying guidance and control algorithms are investigated in terms of required velocity increment Delta-v, and tracking error for a Chief/Deputy satellite system.

  6. 20. Joint Estimation and Calibration for Motion Sensor

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

    Author : Peng Liu; [2020]
    Keywords : State space model; accelerometer array; parameter estimation; Maximum Likelihood; Expectation Maximization; Gradient Descent; ill-conditioned matrix.; tillståndsmodell; accelerometerarray; parameterskattning; maximimetoden; väntevärdesmaximering; gradientsökning; illakonditionerade matriser.;

    Abstract : In the thesis, a calibration method for positions of each accelerometer in an Inertial Sensor Array (IMU) sensor array is designed and implemented. In order to model the motion of the sensor array in the real world, we build up a state space model. Based on the model we use, the problem is to estimate the parameters within the state space model.
