1. 6. On Tailbiting Codes from Convolutional Codes

   Författare :Per Ståhl; Institutionen för elektro- och informationsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; computer technology; Systems engineering; Teknik; Technological sciences; encoder inverse; systematic feedback encoder; state complexity; trellis; tailbiting termination method; tailbiting code; channel coding; convolutional code; Data- och systemvetenskap; Informatics; systems theory; Informatik; systemteori;

   Sammanfattning : Tailbiting is a method to terminate convolutional codes into block codes. We call these block codes tailbiting codes. This thesis focuses on the encoding of tailbiting codes. The tailbiting method is carefully investigated. LÄS MER

3. 7. Voronoi-Based Coding

   Författare :Erik Agrell; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Voronoi diagram; linear block code; Gaussian channel; neighbor descent; nearest neighbor search algorithm; computational geometry; asymptotic theory; source coding; lattice; vector quantization; soft-decision decoding; index assignment; channel coding; complexity;

   Sammanfattning : The performance of a digital communication system can generally be improved by increasing the number of variables being jointly coded. In this sense, it is desirable to have, e.g., higher-dimensional quantizers, longer channel codes, and more users in a multiple-access system. LÄS MER

4. 8. Source and Channel Coding for Compressed Sensing and Control

   Författare :Amirpasha Shirazinia; Mikael Skoglund; Pier Luigi Dragotti; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Source coding; quantization; channel coding; compressed sensing; control; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : Rapid advances in sensor technologies have fueled massive torrents of data streaming across networks. Such large volume of information, indeed, restricts the operational performance of data processing, causing inefficiency in sensing, computation, communication and control. LÄS MER

5. 9. Transition-Based Natural Language Parsing with Dependency and Constituency Representations

   Författare :Johan Hall; Joakim Nivre; Welf Löwe; Sandra Kübler; Växjö universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Natural Language Parsing; Syntactic Parsing; Dependency Structure; Phrase Structure; Machine Learning; Computer science; Datavetenskap; Computer and Information Sciences Computer Science; Data- och informationsvetenskap;

   Sammanfattning : Denna doktorsavhandling undersöker olika aspekter av automatisk syntaktisk analys av texter på naturligt språk. En parser eller syntaktisk analysator, som vi definierar den i denna avhandling, har till uppgift att skapa en syntaktisk analys för varje mening i en text på naturligt språk. LÄS MER

7. 10. Probabilistic Programming for Birth-Death Models of Evolution

   Författare :Jan Kudlicka; Johannes Borgström; Thomas B. Schön; Lawrence M. Murray; Bret Larget; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; probabilistic programming; birth-death models; statistical phylogenetics; particle filters; sequential Monte Carlo SMC ; Computer Science; Datavetenskap;

   Sammanfattning : Phylogenetic birth-death models constitute a family of generative models of evolution. In these models an evolutionary process starts with a single species at a certain time in the past, and the speciations—splitting one species into two descendant species—and extinctions are modeled as events of non-homogenous Poisson processes.
