  1. 1. Asymmetric Bregman Forward-Backward Splitting with Projection Correction

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Max Nilsson; [2022]
    Keywords : Technology and Engineering;

    Abstract : This thesis examines first-order Bregman algorithms in a primal and a primal-dual setting. The Bregman gradient descent algorithm is introduced from a majorization-minimization perspective and as a generalization of the gradient descent algorithm. READ MORE

  3. 2. Finding an Optimal Trajectory for Autonomous Parking Under Uncertain Conditions

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

    Author : Vidar Greinsmark; Tommy Hjertberg; [2019]
    Keywords : RRT; autonomous parking; trajectory planning; optimisation; warm start; heuristics;

    Abstract : Path planning that considers accurate vehicle dynamics and obstacle avoidance is an important problem in the area of autonomous driving. This paper describes a method of implementing trajectory planning for autonomous parking in conditions where the starting point and the position of fixed obstacles are uncertain. READ MORE

  4. 3. A Multi-Target Graph-Constrained HMM Localisation Approach using Sparse Wi-Fi Sensor Data

    University essay from KTH/Optimeringslära och systemteori

    Author : Simon Danielsson; Jakob Flygare; [2018]
    Keywords : Hidden Markov Model; Localisation; Wi-Fi Sensors; Forward-Backward Algorithm; Baum-Welch Algorithm; Machine Learning; Time Series Analysis.; Hidden Markov Model; Lokalisering; Wi-Fi Sensorer; Forward-Backward Algoritm; Baum-Welch Algoritm; Maskinlärning; Tidsserieanalys.;

    Abstract : This thesis explored the possibilities of using a Hidden Markov Model approach for multi-target localisation in an urban environment, with observations generated from Wi-Fi sensors. The area is modelled as a network of nodes and arcs, where the arcs represent sidewalks in the area and constitutes the hidden states in the model. READ MORE

  5. 4. Evaluation of flexible SPA based LPDC decoder using hardware friendly approximation methods

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Afshin Seraj; Deepak Yadav; [2017]
    Keywords : forward-backward; SPA; soft-xor; sum product algorithm; approximation; decoder; LDPC; Technology and Engineering;

    Abstract : Due to computation-intensive nature of LDPC decoders, a lot of research is going towards efficient implementation of their original algorithm (SPA). As "Min-Sum" approximation is basically an overestimation of SPA, this thesis investigates more accurate, yet area efficient, approximations of SPA, to select an optimum one. READ MORE
