Now, for the first time, publication of the landmark work in
backpropagation Scientists, engineers, statisticians, operations
researchers, and other investigators involved in neural networks
have long sought direct access to Paul Werbos's groundbreaking,
much-cited 1974 Harvard doctoral thesis, The Roots of
Backpropagation, which laid the foundation of backpropagation. Now,
with the publication of its full text, these practitioners can go
straight to the original material and gain a deeper, practical
understanding of this unique mathematical approach to social
studies and related fields. In addition, Werbos has provided three
more recent research papers, which were inspired by his original
work, and a new guide to the field. Originally written for readers
who lacked any knowledge of neural nets, The Roots of
Backpropagation firmly established both its historical and
continuing significance as it:
* Demonstrates the ongoing value and new potential of
backpropagation
* Creates a wealth of sound mathematical tools useful across
disciplines
* Sets the stage for the emerging area of fast automatic
differentiation
* Describes new designs for forecasting and control which exploit
backpropagation
* Unifies concepts from Freud, Jung, biologists, and others into a
new mathematical picture of the human mind and how it works
* Certifies the viability of Deutsch's model of nationalism as a
predictive tool--as well as the utility of extensions of this
central paradigm
"What a delight it was to see Paul Werbos rediscover Freud's
version of 'back-propagation.' Freud was adamant (in The Project
for a Scientific Psychology) that selective learning could only
take place if the presynaptic neuron was as influenced as is the
postsynaptic neuron during excitation. Such activation of both
sides of the contact barrier (Freud's name for the synapse) was
accomplished by reducing synaptic resistance by the absorption of
'energy' at the synaptic membranes. Not bad for 1895 But Werbos
1993 is even better." --Karl H. Pribram Professor Emeritus,
Stanford University
With the widespread knowledge and use of e-government, the intent
and evaluation of e-government services continues to focus on
meeting the needs and satisfaction of its citizens. E-Government
Services Design, Adoption, and Evaluation is a comprehensive
collection of research on assessment and implementation of
electronic/digital government technologies in organizations. This
book aims to supply academics, practitioners and professionals with
the understanding of e-government and its applications and impact
on organizations around the world.
This book takes a foundational approach to the semantics of
probabilistic programming. It elaborates a rigorous Markov chain
semantics for the probabilistic typed lambda calculus, which is the
typed lambda calculus with recursion plus probabilistic choice. The
book starts with a recapitulation of the basic mathematical tools
needed throughout the book, in particular Markov chains, graph
theory and domain theory, and also explores the topic of inductive
definitions. It then defines the syntax and establishes the Markov
chain semantics of the probabilistic lambda calculus and,
furthermore, both a graph and a tree semantics. Based on that, it
investigates the termination behavior of probabilistic programs. It
introduces the notions of termination degree, bounded termination
and path stoppability and investigates their mutual relationships.
Lastly, it defines a denotational semantics of the probabilistic
lambda calculus, based on continuous functions over probability
distributions as domains. The work mostly appeals to researchers in
theoretical computer science focusing on probabilistic programming,
randomized algorithms, or programming language theory.
Ada's Legacy illustrates the depth and diversity of writers,
thinkers, and makers who have been inspired by Ada Lovelace, the
English mathematician and writer. The volume, which commemorates
the bicentennial of Ada's birth in December 1815, celebrates
Lovelace's many achievements as well as the impact of her life and
work, which reverberated widely since the late nineteenth century.
In the 21st century we have seen a resurgence in Lovelace
scholarship, thanks to the growth of interdisciplinary thinking and
the expanding influence of women in science, technology,
engineering and mathematics. Ada's Legacy is a unique contribution
to this scholarship, thanks to its combination of papers on Ada's
collaboration with Charles Babbage, Ada's position in the Victorian
and Steampunk literary genres, Ada's representation in and
inspiration of contemporary art and comics, and Ada's continued
relevance in discussions around gender and technology in the
digital age. With the 200th anniversary of Ada Lovelace's birth on
December 10, 2015, we believe that the timing is perfect to publish
this collection of papers. Because of its broad focus on subjects
that reach far beyond the life and work of Ada herself, Ada's
Legacy will appeal to readers who are curious about Ada's enduring
importance in computing and the wider world.
In recent years, we have observed that many educational systems,
especially intelligent tutoring systems, are being implemented
according to an agent paradigm. Therefore, researchers in education
believe that the educational computing environments would be more
pedagogically effective if they had mechanisms to show and
recognize the student's emotions. ""Agent-based Tutoring Systems by
Cognitive and Affective Modeling"" intends to present a modern view
of intelligent tutoring, focusing mainly on the conception of these
systems according to a multi-agent approach and on the affective
and cognitive modeling of the student in this kind of educational
environment. Providing researchers, academicians, educators, and
practitioners with a critical mass of research on the theory,
practice, development, and implementation of tools for knowledge
representation and agent-based architectures, this Premier
Reference Source is a must-have addition to every library
collection.
The third edition of this handbook is designed to provide a broad
coverage of the concepts, implementations, and applications in
metaheuristics. The book's chapters serve as stand-alone
presentations giving both the necessary underpinnings as well as
practical guides for implementation. The nature of metaheuristics
invites an analyst to modify basic methods in response to problem
characteristics, past experiences, and personal preferences, and
the chapters in this handbook are designed to facilitate this
process as well. This new edition has been fully revised and
features new chapters on swarm intelligence and automated design of
metaheuristics from flexible algorithm frameworks. The authors who
have contributed to this volume represent leading figures from the
metaheuristic community and are responsible for pioneering
contributions to the fields they write about. Their collective work
has significantly enriched the field of optimization in general and
combinatorial optimization in particular.Metaheuristics are
solution methods that orchestrate an interaction between local
improvement procedures and higher level strategies to create a
process capable of escaping from local optima and performing a
robust search of a solution space. In addition, many new and
exciting developments and extensions have been observed in the last
few years. Hybrids of metaheuristics with other optimization
techniques, like branch-and-bound, mathematical programming or
constraint programming are also increasingly popular. On the front
of applications, metaheuristics are now used to find high-quality
solutions to an ever-growing number of complex, ill-defined
real-world problems, in particular combinatorial ones. This
handbook should continue to be a great reference for researchers,
graduate students, as well as practitioners interested in
metaheuristics.
This volume is proceedings of the international conference of the
Parallel Computational Fluid Dynamics 2002. In the volume,
up-to-date information about numerical simulations of flows using
parallel computers is given by leading researchers in this field.
Special topics are "Grid Computing" and "Earth Simulator." Grid
computing is now the most exciting topic in computer science. An
invited paper on grid computing is presented in the volume. The
Earth-Simulator is now the fastest computer in the world. Papers on
flow-simulations using the Earth-Simulator are also included, as
well as a thirty-two page special tutorial article on numerical
optimization.
This textbook provides concise coverage of the basics of linear and
integer programming which, with megatrends toward optimization,
machine learning, big data, etc., are becoming fundamental toolkits
for data and information science and technology. The authors'
approach is accessible to students from almost all fields of
engineering, including operations research, statistics, machine
learning, control system design, scheduling, formal verification
and computer vision. The presentations enables the basis for
numerous approaches to solving hard combinatorial optimization
problems through randomization and approximation. Readers will
learn to cast various problems that may arise in their research as
optimization problems, understand the cases where the optimization
problem will be linear, choose appropriate solution methods and
interpret results appropriately.
This book provides a comprehensive account of the glowworm swarm
optimization (GSO) algorithm, including details of the underlying
ideas, theoretical foundations, algorithm development, various
applications, and MATLAB programs for the basic GSO algorithm. It
also discusses several research problems at different levels of
sophistication that can be attempted by interested researchers. The
generality of the GSO algorithm is evident in its application to
diverse problems ranging from optimization to robotics. Examples
include computation of multiple optima, annual crop planning,
cooperative exploration, distributed search, multiple source
localization, contaminant boundary mapping, wireless sensor
networks, clustering, knapsack, numerical integration, solving
fixed point equations, solving systems of nonlinear equations, and
engineering design optimization. The book is a valuable resource
for researchers as well as graduate and undergraduate students in
the area of swarm intelligence and computational intelligence and
working on these topics.
The advancement of information technology is becoming more
prevalent in all aspects of the world today, including online
environments. Understanding technology's effect on niche markets
and all fields of research is crucial for practitioners in this
area. Contemporary Advancements in Information Technology
Development in Dynamic Environments presents an in-depth discussion
into the information technology revolution present in fields such
as government, gaming, social networking, and cloud computing. This
book's investigation into the research and application of
information technology in several specific areas make this a useful
resource for practitioners, professionals, undergraduate/graduate
students, and academics.

This volume contains proceedings of two conferences held in Toronto
(Canada) and Kozhikode (India) in 2016 in honor of the 60th
birthday of Professor Kumar Murty. The meetings were focused on
several aspects of number theory: The theory of automorphic forms
and their associated L-functions Arithmetic geometry, with special
emphasis on algebraic cycles, Shimura varieties, and explicit
methods in the theory of abelian varieties The emerging
applications of number theory in information technology Kumar Murty
has been a substantial influence in these topics, and the two
conferences were aimed at honoring his many contributions to number
theory, arithmetic geometry, and information technology.
This book puts in one place and in accessible form Richard Berk's
most recent work on forecasts of re-offending by individuals
already in criminal justice custody. Using machine learning
statistical procedures trained on very large datasets, an explicit
introduction of the relative costs of forecasting errors as the
forecasts are constructed, and an emphasis on maximizing
forecasting accuracy, the author shows how his decades of research
on the topic improves forecasts of risk. Criminal justice risk
forecasts anticipate the future behavior of specified individuals,
rather than "predictive policing" for locations in time and space,
which is a very different enterprise that uses different data
different data analysis tools. The audience for this book includes
graduate students and researchers in the social sciences, and data
analysts in criminal justice agencies. Formal mathematics is used
only as necessary or in concert with more intuitive explanations.
This volume of selected and peer-reviewed contributions on the
latest developments in time series analysis and forecasting updates
the reader on topics such as analysis of irregularly sampled time
series, multi-scale analysis of univariate and multivariate time
series, linear and non-linear time series models, advanced time
series forecasting methods, applications in time series analysis
and forecasting, advanced methods and online learning in time
series and high-dimensional and complex/big data time series. The
contributions were originally presented at the International
Work-Conference on Time Series, ITISE 2016, held in Granada, Spain,
June 27-29, 2016. The series of ITISE conferences provides a forum
for scientists, engineers, educators and students to discuss the
latest ideas and implementations in the foundations, theory, models
and applications in the field of time series analysis and
forecasting. It focuses on interdisciplinary and multidisciplinary
research encompassing the disciplines of computer science,
mathematics, statistics and econometrics.
Numerical partial differential equations (PDEs) are an important
part of numerical simulation, the third component of the modern
methodology for science and engineering, besides the traditional
theory and experiment. This volume contains papers that originated
with the collaborative research of the teams that participated in
the IMA Workshop for Women in Applied Mathematics: Numerical
Partial Differential Equations and Scientific Computing in August
2014.
An essential contribution to the study of the history of
computers, this work identifies the computer's impact on the
physical, biological, cognitive, and medical sciences. References
fundamental to the understudied area of the history of scientific
computing also document the significant role of the sciences in
helping to shape the development of computer technology. More
broadly, the many resources on scientific computing help
demonstrate how the computer was the most significant scientific
instrument of the 20th century.
The only guide of its kind covering the use and impact of
computers on the the physical, biological, medical, and cognitive
sciences, it contains more than 1,000 annotated citations to
carefully selected secondary and primary resources. Historians of
technology and science will find this a very useful resource.
Computer scientists, physicians, biologists, chemists, and
geologists will also benefit from this extensive bibliography on
the history of computer applications and the sciences.
The book is designed to help children learn and understand the
concepts of a computer. It gives them step by step instructions and
leads them through the process on how to do something. The book
also provides screenshots so the child can also use visual
associations with the words that he/she is reading. They also have
some exercises in the book that they can do to help them remember
what was taught to them. Children learn at an early age and soak up
the knowledge. It is best to give them as much information, and to
display that information, in as many ways as possible. By the time
your child reads this book, they will have a very good basic, but
yet strong foundation of the Microsoft Windows operating system.
The book is meant for anyone, not only children, to be able to pick
it up, read it, and understand it from a non-technical standpoint.
Please look towards the back of the book to contact the author for
any pre-sales questions or comments.
This book aims at presenting the field of Quantum Information
Theory in an intuitive, didactic and self-contained way, taking
into account several multidisciplinary aspects. Therefore, this
books is particularly suited to students and researchers willing to
grasp fundamental concepts in Quantum Computation and Quantum
Information areas. The field of Quantum Information Theory has
increased significantly over the last three decades. Many results
from classical information theory were translated and extended to a
scenario where quantum effects become important. Most of the
results in this area allows for an asymptotically small probability
of error to represent and transmit information efficiently. Claude
E.Shannon was the first scientist to realize that error-free
classical information transmission can be accomplished under
certain conditions. More recently, the concept of error-free
classical communication was translated to the quantum context. The
so-called Quantum Zero-Error Information Theory completes and
extends the Shannon Zero-Error Information Theory.
In many international settings, regional economies are declining
resulting in lowered opportunities for these communities. This
result attacks the very fabric of cohesion and purpose for these
regional societies, and increases social, health, economic and
sustainability problems. Community Informatics research, education
and practice is an emerging area in many countries, which seeks to
address these issues. Encyclopedia of Developing Regional
Communities with Information and Communication Technology provides
leaders, policy developers, researchers, students and community
workers with successful strategies and principles of Community
Informatics to transform regions. This encyclopedia develops an
integrative cross-sectoral approach in the use of Community
Informatics to increase both social and cultural capital as a means
to increased sustainability for regional communities.
