Issues in the Use of Neural Networks in Information Retrieval
by Iuliana F. IatanThis book highlights the ability of neural networks (NNs) to be excellent pattern matchers and their importance in information retrieval (IR), which is based on index term matching. The book defines a new NN-based method for learning image similarity and describes how to use fuzzy Gaussian neural networks to predict personality. It introduces the fuzzy Clifford Gaussian network, and two concurrent neural models: (1) concurrent fuzzy nonlinear perceptron modules, and (2) concurrent fuzzy Gaussian neural network modules. Furthermore, it explains the design of a new model of fuzzy nonlinear perceptron based on alpha level sets and describes a recurrent fuzzy neural network model with a learning algorithm based on the improved particle swarm optimization method.

It Came from Something Awful: How a Toxic Troll Army Accidentally Memed Donald Trump into Office
by Dale BeranHow 4chan and 8chan fuel white nationalism, inspire violence, and infect politics.The internet has transformed the ways we think and act, and by consequence, our politics. The most impactful recent political movements on the far left and right started with massive online collectives of teenagers. Strangely, both movements began on the same website: an anime imageboard called 4chan.org. It Came from Something Awful is the fascinating and bizarre story of sites like 4chan and 8chan and their profound effect on youth counterculture.Dale Beran has observed the anonymous messageboard community's shifting activities and interests since the beginning. Sites like 4chan and 8chan are microcosms of the internet itself—simultaneously at the vanguard of contemporary culture, politics, comedy and language, and a new low for all of the above. They were the original meme machines, mostly frequented by socially awkward and disenfranchised young men in search of a place to be alone together.During the recession of the late 2000’s, the memes became political. 4chan was the online hub of a leftist hacker collective known as Anonymous and a prominent supporter of the Occupy Wall Street movement. But within a few short years, the site’s ideology spun on its axis; it became the birthplace and breeding ground of the alt-right. In It Came from Something Awful, Beran uses his insider’s knowledge and natural storytelling ability to chronicle 4chan's strange journey from creating rage-comics to inciting riots to—according to some—memeing Donald Trump into the White House.

by Gary Miner Scott Burk David SweenorUp to 70% and even more of corporate Analytics Efforts fail!!! Even after these corporations have made very large investments, in time, talent, and money, in developing what they thought were good data and analytics programs. Why? Because the executives and decision makers and the entire analytics team have not considered the most important aspect of making these analytics efforts successful. In this Book II of "It’s All Analytics!" series, we describe two primary things: 1) What this "most important aspect" consists of, and 2) How to get this "most important aspect" at the center of the analytics effort and thus make your analytics program successful. This Book II in the series is divided into three main parts: Part I, Organizational Design for Success, discusses ……. The need for a complete company / organizational Alignment of the entire company and its analytics team for making its analytics successful. This means attention to the culture – the company culture culture!!! To be successful, the CEO’s and Decision Makers of a company / organization must be fully cognizant of the cultural focus on ‘establishing a center of excellence in analytics’. Simply, "culture – company culture" is the most important aspect of a successful analytics program. The focus must be on innovation, as this is needed by the analytics team to develop successful algorithms that will lead to greater company efficiency and increased profits. Part II, Data Design for Success, discusses ….. Data is the cornerstone of success with analytics. You can have the best analytics algorithms and models available, but if you do not have good data, efforts will at best be mediocre if not a complete failure. This Part II also goes further into data with descriptions of things like Volatile Data Memory Storage and Non-Volatile Data Memory Storage, in addition to things like data structures and data formats, plus considering things like Cluster Computing, Data Swamps, Muddy Data, Data Marts, Enterprise Data Warehouse, Data Reservoirs, and Analytic Sandboxes, and additionally Data Virtualization, Curated Data, Purchased Data, Nascent & Future Data, Supplemental Data, Meaningful Data, GIS (Geographic Information Systems) & Geo Analytics Data, Graph Databases, and Time Series Databases. Part II also considers Data Governance including Data Integrity, Data Security, Data Consistency, Data Confidence, Data Leakage, Data Distribution, and Data Literacy. Part III, Analytics Technology Design for Success, discusses ….

Italian Modern Art in the Age of Fascism (Routledge Research in Art and Politics)
by Anthony WhiteThis book examines the work of several modern artists, including Fortunato Depero, Scipione, and Mario Radice, who were working in Italy during the time of Benito Mussolini’s rise and fall. It provides a new history of the relationship between modern art and fascism. The study begins from the premise that Italian artists belonging to avant-garde art movements, such as futurism, expressionism, and abstraction, could produce works that were perfectly amenable to the ideologies of Mussolini’s regime. A particular focus of the book is the precise relationship between ideas of history and modernity encountered in the art and politics of the time and how compatible these truly were.

Iterative Learning Control over Random Fading Channels
by Xinghuo Yu Dong ShenRandom fading communication is a type of attenuation damage of data over certain propagation media. Establishing a systematic framework for the design and analysis of learning control schemes, the book studies in depth the iterative learning control for stochastic systems with random fading communication. The authors introduce both cases where the statistics of the random fading channels are known in advance and unknown. They then extend the framework to other systems, including multi-agent systems, point-to-point tracking systems, and multi-sensor systems. More importantly, a learning control scheme is established to solve the multi-objective tracking problem with faded measurements, which can help practical applications of learning control for high-precision tracking of networked systems. The book will be of interest to researchers and engineers interested in learning control, data-driven control, and networked control systems.

Providing important insights and useful methods and practical algorithms that can potentially be applied in batch process control and optimization, it is a valuable resource for researchers, scientists, and engineers in the field of process system engineering and control engineering.
Iterative Optimizers: Difficulty Measures and Benchmarks
by Maurice ClercAlmost every month, a new optimization algorithm is proposed, often accompanied by the claim that it is superior to all those that came before it. However, this claim is generally based on the algorithm’s performance on a specific set of test cases, which are not necessarily representative of the types of problems the algorithm will face in real life. This book presents the theoretical analysis and practical methods (along with source codes) necessary to estimate the difficulty of problems in a test set, as well as to build bespoke test sets consisting of problems with varied difficulties. The book formally establishes a typology of optimization problems, from which a reliable test set can be deduced. At the same time, it highlights how classic test sets are skewed in favor of different classes of problems, and how, as a result, optimizers that have performed well on test problems may perform poorly in real life scenarios.

J2EE Design Patterns: Patterns in the Real World
by William Crawford Jonathan KaplanArchitects of buildings and architects of software have more in common than most people think. Both professions require attention to detail, and both practitioners will see their work collapse around them if they make too many mistakes. It's impossible to imagine a world in which buildings get built without blueprints, but it's still common for software applications to be designed and built without blueprints, or in this case, design patterns.A software design pattern can be identified as "a recurring solution to a recurring problem." Using design patterns for software development makes sense in the same way that architectural design patterns make sense--if it works well in one place, why not use it in another? But developers have had enough of books that simply catalog design patterns without extending into new areas, and books that are so theoretical that you can't actually do anything better after reading them than you could before you started.Crawford and Kaplan's J2EE Design Patterns approaches the subject in a unique, highly practical and pragmatic way. Rather than simply present another catalog of design patterns, the authors broaden the scope by discussing ways to choose design patterns when building an enterprise application from scratch, looking closely at the real world tradeoffs that Java developers must weigh when architecting their applications. Then they go on to show how to apply the patterns when writing realworld software. They also extend design patterns into areas not covered in other books, presenting original patterns for data modeling, transaction / process modeling, and interoperability.J2EE Design Patterns offers extensive coverage of the five problem areas enterprise developers face:Maintenance (Extensibility)Performance (System Scalability)Data Modeling (Business Object Modeling)Transactions (process Modeling)Messaging (Interoperability)And with its careful balance between theory and practice, J2EE Design Patterns will give developers new to the Java enterprise development arena a solid understanding of how to approach a wide variety of architectural and procedural problems, and will give experienced J2EE pros an opportunity to extend and improve on their existing experience.
