Content-Based Audio Classification and Retrieval for Audiovisual
Data Parsing is an up-to-date overview of audio and video content
analysis. Included is extensive treatment of audiovisual data
segmentation, indexing and retrieval based on multimodal media
content analysis, and content-based management of audio data. In
addition to the commonly studied audio types such as speech and
music, the authors have included hybrid types of sounds that
contain more than one kind of audio component such as speech or
environmental sound with music in the background. Emphasis is also
placed on semantic-level identification and classification of
environmental sounds. The authors introduce a new generic audio
retrieval system on top of the audio archiving schemes. Both
theoretical analysis and implementation issues are presented. The
developing MPEG-7 standards are explored. Content-Based Audio
Classification and Retrieval for Audiovisual Data Parsing will be
especially useful to researchers and graduate level students
designing and developing fully functional audiovisual systems for
audio/video content parsing of multimedia streams.
Data mining is a mature technology. The prediction problem, looking
for predictive patterns in data, has been widely studied. Strong
me- ods are available to the practitioner. These methods process
structured numerical information, where uniform measurements are
taken over a sample of data. Text is often described as
unstructured information. So, it would seem, text and numerical
data are different, requiring different methods. Or are they? In
our view, a prediction problem can be solved by the same methods,
whether the data are structured - merical measurements or
unstructured text. Text and documents can be transformed into
measured values, such as the presence or absence of words, and the
same methods that have proven successful for pred- tive data mining
can be applied to text. Yet, there are key differences. Evaluation
techniques must be adapted to the chronological order of
publication and to alternative measures of error. Because the data
are documents, more specialized analytical methods may be preferred
for text. Moreover, the methods must be modi?ed to accommodate very
high dimensions: tens of thousands of words and documents. Still,
the central themes are similar.
Environmental protection and resource recovery are two crucial
issues facing our society in the 21st century. Anaerobic
biotechnology has become widely accepted by the wastewater industry
as the better alternative to the more conventional but costly
aerobic process and tens of thousands of full-scale facilities
using this technology have been installed worldwide in the past two
decades. Anaerobic Biotechnology is the sequel to the well-received
Environmental Anaerobic Technology: Applications and New
Developments (2010) and compiles developments over the past five
years. This volume contains contributions from 48 renowned experts
from across the world, including Gatze Lettinga, laureate of the
2007 Tyler Prize and the 2009 Lee Kuan Yew Water Prize, and Perry
McCarty, whose pioneering work laid the foundations for today's
anaerobic biotechnology. This book is ideal for engineers and
scientists working in the field, as well as decision-makers on
energy and environmental policies.
The Riemann problem is the most fundamental problem in the entire
field of non-linear hyperbolic conservation laws. Since first posed
and solved in 1860, great progress has been achieved in the
one-dimensional case. However, the two-dimensional case is
substantially different. Although research interest in it has
lasted more than a century, it has yielded almost no analytical
demonstration. It remains a great challenge for mathematicians.
This volume presents work on the two-dimensional Riemann problem
carried out over the last 20 years by a Chinese group. The authors
explore four models: scalar conservation laws, compressible Euler
equations, zero-pressure gas dynamics, and pressure-gradient
equations. They use the method of generalized characteristic
analysis plus numerical experiments to demonstrate the elementary
field interaction patterns of shocks, rarefaction waves, and slip
lines. They also discover a most interesting feature for
zero-pressure gas dynamics: a new kind of elementary wave appearing
in the interaction of slip lines-a weighted Dirac delta shock of
the density function. The Two-Dimensional Riemann Problem in Gas
Dynamics establishes the rigorous mathematical theory of
delta-shocks and Mach reflection-like patterns for zero-pressure
gas dynamics, clarifies the boundaries of interaction of elementary
waves, demonstrates the interesting spatial interaction of slip
lines, and proposes a series of open problems. With applications
ranging from engineering to astrophysics, and as the first book to
examine the two-dimensional Riemann problem, this volume will prove
fascinating to mathematicians and hold great interest for
physicists and engineers.
The mathematical theory of machine learning not only explains the
current algorithms but can also motivate principled approaches for
the future. This self-contained textbook introduces students and
researchers of AI to the main mathematical techniques used to
analyze machine learning algorithms, with motivations and
applications. Topics covered include the analysis of supervised
learning algorithms in the iid setting, the analysis of neural
networks (e.g. neural tangent kernel and mean-field analysis), and
the analysis of machine learning algorithms in the sequential
decision setting (e.g. online learning, bandit problems, and
reinforcement learning). Students will learn the basic mathematical
tools used in the theoretical analysis of these machine learning
problems and how to apply them to the analysis of various concrete
algorithms. This textbook is perfect for readers who have some
background knowledge of basic machine learning methods, but want to
gain sufficient technical knowledge to understand research papers
in theoretical machine learning.
One consequence of the pervasive use of computers is that most
documents originate in digital form. Widespread use of the Internet
makes them readily available. Text mining - the process of
analyzing unstructured natural-language text - is concerned with
how to extract information from these documents. Developed from the
authors' highly successful Springer reference on text mining,
Fundamentals of Predictive Text Mining is an introductory textbook
and guide to this rapidly evolving field. Integrating topics
spanning the varied disciplines of data mining, machine learning,
databases, and computational linguistics, this uniquely useful book
also provides practical advice for text mining. In-depth
discussions are presented on issues of document classification,
information retrieval, clustering and organizing documents,
information extraction, web-based data-sourcing, and prediction and
evaluation. Background on data mining is beneficial, but not
essential. Where advanced concepts are discussed that require
mathematical maturity for a proper understanding, intuitive
explanations are also provided for less advanced readers. Topics
and features: presents a comprehensive, practical and easy-to-read
introduction to text mining; includes chapter summaries, useful
historical and bibliographic remarks, and classroom-tested
exercises for each chapter; explores the application and utility of
each method, as well as the optimum techniques for specific
scenarios; provides several descriptive case studies that take
readers from problem description to systems deployment in the real
world; includes access to industrial-strength text-mining software
that runs on any computer; describes methods that rely on basic
statistical techniques, thus allowing for relevance to all
languages (not just English); contains links to free downloadable
software and other supplementary instruction material. Fundamentals
of Predictive Text Mining is an essential resource for IT
professionals and managers, as well as a key text for advanced
undergraduate computer science students and beginning graduate
students. Dr. Sholom M. Weiss is a Research Staff Member with the
IBM Predictive Modeling group, in Yorktown Heights, New York, and
Professor Emeritus of Computer Science at Rutgers University. Dr.
Nitin Indurkhya is Professor at the School of Computer Science and
Engineering, University of New South Wales, Australia, as well as
founder and president of data-mining consulting company Data-Miner
Pty Ltd. Dr. Tong Zhang is Associate Professor at the Department of
Statistics and Biostatistics at Rutgers University, New Jersey.
