   Abstract : This thesis is based on nine papers, all concerned with parameter estimation. The thesis aims at solving problems related to real-world applications such as spectroscopy, DNA sequencing, and audio processing, using sparse modeling heuristics. READ MORE

6. 4. Estimation and optimal input design in sparse models

   Author : Javad Parsa; Håkan Hjalmarsson; Kim Batselier; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; System identification; Sparse estimation; Input design; Electrical Engineering; Elektro- och systemteknik;

   Abstract : Sparse parameter estimation is an important aspect of system identification, as it allows for reducing the order of a model, and also some models in system identification inherently exhibit sparsity in their parameters. The accuracy of the estimated sparse model depends directly on the performance of the sparse estimation methods. READ MORE

7. 5. Estimation for Sensor Fusion and Sparse Signal Processing

   Author : Dave Zachariah; Magnus Jansson; Fredrik Gustafsson; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Estimation theory; sensor fusion; sparse signal processing;

   Abstract : Progressive developments in computing and sensor technologies during the past decades have enabled the formulation of increasingly advanced problems in statistical inference and signal processing. The thesis is concerned with statistical estimation methods, and is divided into three parts with focus on two different areas: sensor fusion and sparse signal processing. READ MORE
