1. Asymmetric Bregman Forward-Backward Splitting with Projection Correction
Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknikSammanfattning : 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. LÄS MER
2. Finding an Optimal Trajectory for Autonomous Parking Under Uncertain Conditions
Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : 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. LÄS MER
3. A Multi-Target Graph-Constrained HMM Localisation Approach using Sparse Wi-Fi Sensor Data
Master-uppsats, KTH/Optimeringslära och systemteoriSammanfattning : 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. LÄS MER
4. Evaluation of flexible SPA based LPDC decoder using hardware friendly approximation methods
Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknikSammanfattning : 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. LÄS MER
