  1. 1. Assessing the Streamline Plausibility Through Convex Optimization for Microstructure Informed Tractography(COMMIT) with Deep Learning

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Xinyi Wan; [2023]
    Keywords : Tractography; dMRI; Filtering Methods; Deep Learning; Classification;

    Abstract : Tractography is widely used in the brain connectivity study from diffusion magnetic resonance imaging data. However, lack of ground truth and plenty of anatomically implausible streamlines in the tractograms have caused challenges and concerns in the use of tractograms such as brain connectivity study.

  2. 2. Estimating Believed Knowledge of Portfolio Agents Using Inverse Optimization

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

    Author : Gustaf Zachrisson; Oscar Wink; [2022]
    Keywords : ;

    Abstract : In this report, we demonstrate the utility of inverse optimization in convex programming by applying it on estimating financial market beliefs and behaviors of portfolio investors. The inversion of the optimization  utilized the Karush–Kuhn–Tucker optimality conditions specified for the current situation. READ MORE

  3. 3. Far-field pattern synthesis of transmitarray antennas using convex optimization techniques

    University essay from KTH/Tillämpad fysik

    Author : Marie Defives; [2022]
    Keywords : Applied physics; Transmitarray antennas; convex optimization; Tillämpad fysik; Transmitarray-antenner; konvex optimering;

    Abstract : Transmitarrays antennas (TAs) can be seen as the planar counterpart of optical lenses. They are composed of thin radiating elements (unit cells) which introduce different local phase shifts on an incident electromagnetic wave, emitted by a primary source, and re-radiate it. READ MORE

  4. 4. Predictive Energy Management of Long-Haul Hybrid Trucks : Using Quadratic Programming and Branch-and-Bound

    University essay from Linköpings universitet/Fordonssystem

    Author : Erik Jonsson Holm; [2021]
    Keywords : Predictive energy management; quadratic programming; branch-and-bound; mixed-integer quadratic programming; energy optimization; look-ahead control; model predictive control; receding horizon control; optimal control; convex optimization; heavy-duty vehicle; long-haul truck; hybrid electric vehicle;

    Abstract : This thesis presents a predictive energy management controller for long-haul hybrid trucks. In a receding horizon control framework, the vehicle speed reference, battery energy reference, and engine on/off decision are optimized over a prediction horizon. READ MORE

  5. 5. Robustness, Stability and Performance of Optimization Algorithms for GAN Training

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Oskar Larsson; [2021]
    Keywords : Technology and Engineering;

    Abstract : Training Generative Adversial Networks (GANs) for image synthesis problems is a largely heuristical process that is known to be fickle and difficult to set up reliably. To avoid common failure modes and succeed with GAN training, one needs to find very specific hyperparameter settings carefully tuned to the model architectures and datasets at hand. READ MORE
