Bayesian Estimation and Tracking: A Practical Guide

A practical approach to estimating and tracking dynamic systems in real-worl applications Much of the literature on performing estimation for non-Gaussian systems is short on practical methodology, while Gaussian methods often lack a cohesive derivation. Bayesian Estimation and Tracking addresses the gap in the field on both accounts, providing readers with a comprehensive overview of methods for estimating both linear and nonlinear dynamic systems driven by Gaussian and non-Gaussian noices. Featuring a unified approach to Bayesian estimation and tracking, the book emphasizes the derivation of all tracking algorithms within a Bayesian framework and describes effective numerical methods for evaluating density-weighted integrals, including linear and nonlinear Kalman filters for Gaussian-weighted integrals and particle filters for non-Gaussian cases. The author first emphasizes detailed derivations from first principles of eeach estimation method and goes on to use illustrative and detailed step-by-step instructions for each method that makes coding of the tracking filter simple and easy to understand. Case studies are employed to showcase applications of the discussed topics. In addition, the book supplies block diagrams for each algorithm, allowing readers to develop their own MATLAB toolbox of estimation methods. Bayesian Estimation and Tracking is an excellent book for courses on estimation and tracking methods at the graduate level. The book also serves as a valuable reference for research scientists, mathematicians, and engineers seeking a deeper understanding of the topics.

Audiovisual Archives: Digital Text and Discourse Analysis

Today, audiovisual archives and libraries have become very popular especially in the field of collecting, preserving and transmitting cultural heritage. However, the data in these archives or libraries - videos, images, soundtracks, etc. - constitute as such only potential cognitive resources for a given public (or "target community"). One of the most crucial issues of digital audiovisual libraries is indeed to enable users to actively appropriate audiovisual resources for their own concern (in research, education or any other professional or non-professional context). This means, an adaptation of the audiovisual data to the specific needs of a user or user group can be represented by small and closed "communities" as well as by networks of open communities around the globe. "Active appropriation" is, basically speaking, the use of existing digital audiovisual resources by users or user communities according to their expectations, needs, interests or desires. This process presupposes: 1) the definition and development of models or "scenarios" of cognitive processing of videos by the user; 2) the availability of tools necessary for defining, developing, reusing and sharing meta-linguistic resources such as thesauruses, ontologies or description models by users or user communities. Both aspects are central to the so-called semiotic turn in dealing with digital (audiovisual) texts, corpora of texts or again entire (audiovisual) archives and libraries. They demonstrate practically and theoretically the well-known "from data to metadata" or "from (simple) information to (relevant) knowledge" problem, which obviously directly influences the effective use, social impact and relevancy, and therefore also the future, of digital knowledge archives. This book offers a systematic, comprehensive approach to these questions from a theoretical as well as practical point of view. Contents Part 1. The Practical, Technical and Theoretical Context 1. Analysis of an Audiovisual Resource. 2. The Audiovisual Semiotic Workshop (ASW) Studio - A Brief Presentation. 3. A Concrete Example of a Model for Describing Audiovisual Content. 4. Model of Description and Task of Analysis. Part 2. Tasks in Analyzing an Audiovisual Corpus 5. The Analytical Task of "Describing the Knowledge Object". 6. The Analytical Task of "Contextualizing the Domain of Knowledge". 7. The Analytical Task of "Analyzing the Discourse Production around a Subject". Part 3. Procedures of Description 8. Definition of the Domain of Knowledge and Configuration of the Topical Structure. 9. The Procedure of Free Description of an Audiovisual Corpus. 10. The Procedure of Controlled Description of an Audiovisual Corpus. Part 4. The ASW System of Metalinguistic Resources 11. An Overview of the ASW Metalinguistic Resources. 12. The Meta-lexicon Representing the ASW Universe of Discourse.

SAS Encoding

Understanding the basic concepts of character encoding is necessary for creating, manipulating, and rendering any type of character data. An encoding is involved whenever data is brought into SAS from various external sources; whenever data is transferred between SAS applications running different locales or across the network via thin clients; and when output is written to external files, SAS data sets, printers, or Web pages. In each of these cases, something can go wrong. It is the encoder’s responsibility to ensure that the data is stored, processed, and rendered in the correct encoding. Manfred Kiefer's SAS Encoding: Understanding the Details explains the basic concepts of characters, encodings, glyphs, and fonts and gives practical examples of how to troubleshoot encoding problems. Addressed to the beginner as well as to the advanced SAS user, this book can help solve your encoding problems. It provides background information about encodings, shows how they are used with SAS software, and explains typical problems and ways to sort those out. It also presents examples of how to set up SAS software in an international environment.

Mathematical Statistics and Stochastic Processes

Generally, books on mathematical statistics are restricted to the case of independent identically distributed random variables. In this book however, both this case AND the case of dependent variables, i.e. statistics for discrete and continuous time processes, are studied. This second case is very important for today's practitioners. Mathematical Statistics and Stochastic Processes is based on decision theory and asymptotic statistics and contains up-to-date information on the relevant topics of theory of probability, estimation, confidence intervals, non-parametric statistics and robustness, second-order processes in discrete and continuous time and diffusion processes, statistics for discrete and continuous time processes, statistical prediction, and complements in probability. This book is aimed at students studying courses on probability with an emphasis on measure theory and for all practitioners who apply and use statistics and probability on a daily basis.

Textual Information Access: Statistical Models
