Book excerpt: Large-scale, highly interconnected networks, which are often modeled as graphs, pervade both our society and the natural world around us. Uncertainty, on the other hand, is inherent in the underlying data due to a variety of reasons, such as noisy measurements, lack of precise information needs, inference and prediction models, or explicit manipulation, e.g., for privacy purposes. Therefore, uncertain, or probabilistic, graphs are increasingly used to represent noisy linked data in many emerging application scenarios, and they have recently become a hot topic in the database and data mining communities. Many classical algorithms such as reachability and shortest path queries become #P-complete and, thus, more expensive over uncertain graphs. Moreover, various complex queries and analytics are also emerging over uncertain networks, such as pattern matching, information diffusion, and influence maximization queries. In this book, we discuss the sources of uncertain graphs and their applications, uncertainty modeling, as well as the complexities and algorithmic advances on uncertain graphs processing in the context of both classical and emerging graph queries and analytics. We emphasize the current challenges and highlight some future research directions.
Download or read book Picturing the Uncertain World written by Howard Wainer and published by Princeton University Press. This book was released on 2021-06-08 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: In his entertaining and informative book Graphic Discovery, Howard Wainer unlocked the power of graphical display to make complex problems clear. Now he's back with Picturing the Uncertain World, a book that explores how graphs can serve as maps to guide us when the information we have is ambiguous or incomplete. Using a visually diverse sampling of graphical display, from heartrending autobiographical displays of genocide in the Kovno ghetto to the "Pie Chart of Mystery" in a New Yorker cartoon, Wainer illustrates the many ways graphs can be used--and misused--as we try to make sense of an uncertain world. Picturing the Uncertain World takes readers on an extraordinary graphical adventure, revealing how the visual communication of data offers answers to vexing questions yet also highlights the measure of uncertainty in almost everything we do. Are cancer rates higher or lower in rural communities? How can you know how much money to sock away for retirement when you don't know when you'll die? And where exactly did nineteenth-century novelists get their ideas? These are some of the fascinating questions Wainer invites readers to consider. Along the way he traces the origins and development of graphical display, from William Playfair, who pioneered the use of graphs in the eighteenth century, to instances today where the public has been misled through poorly designed graphs. We live in a world full of uncertainty, yet it is within our grasp to take its measure. Read Picturing the Uncertain World and learn how.
Download or read book Cycle Index of Uncertain Random Graph written by Lin Chen and published by Infinite Study. This book was released on with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the increasing of the complexity of a system, there is a variety of indeterminacy in the practical applications of graph theory. We focus on uncertain random graph, in which some edges exist with degrees in probability measure and others exist with degrees in uncertain measure. In this paper, the chance theory is applied to construct the cycle index of an uncertain random graph. Then a method to calculate the cycle index of an uncertain random graph is presented. We also discuss some properties of the cycle index.
Download or read book Discovering Reliable Communities In Uncertain Graphs written by Lin Liu and published by . This book was released on 2015 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: Due to its ubiquity, graph data attracts increasing attention from data mining research community and industrial enterprises, and its application includes social networks (e.g., Facebook, LinkedIn, Myspace), biological networks (e.g., Protein Interaction Network), communication networks (e.g., Peer-to-Peer Network, Wireless ad hoc Network), traffic networks, to name but a few. Not until recently do people start realizing the inherent uncertainty of these applications. For example, due to the high throughput experiment methods and imperfect computational models, the false negative and false positive for detecting protein interactions are very high. In social networks, it is error-prone to model personal relationships as binaries for the imprecise information collection instruments, such as anonymous communication, self-reporting log. Therefore, researchers start interpreting these graph data from the probabilistic perspective. The solutions to many interesting uncertain graph problems are developed upon reliability, the most fundamental concept in uncertain setting and the counterpart of connectivity concept for deterministic graphs. Our work focuses on applying reliability concept to discover reliable community structures from uncertain graphs in different scenarios. First, highly reliable subgraph discovery problem attempts to identify all induced subgraphs for which the probability of connectivity being maintained under uncertainty is at least a user-given threshold. To solve this problem we propose a novel sampling scheme, which transforms the core mining task into a frequent cohesive set mining problem for a set of deterministic graphs. Such transformation enables the development of an efficient two-stage approach which combines a novel peeling technique for maximal set discovery with depth-first search for further enumeration. Second, relevant reliable subgraph mining problem aims to find a subgraph that contains a user-given set of vertices (seed set) and maximizes the lowest pairwise connectivity within this subgraph. To solve this problem, we propose both "adaptive'' deterministic algorithm and "adaptive'' randomized methods: a branch-and-bound method that iteratively enumerates possible candidates while using obtained reliability threshold to prune unpromising candidates on the fly, and an adaptive Metropolis-Hastings sampling method that avoids jumping into the unpromising states based on its search history. Third, uncertain graph clustering problem based on a generalized reliability measurement formulated from information theoretical perspective, aims to partition an uncertain graph into a set of subgraphs, each of which is not likely to be disconnected in the context of different instantiations of uncertain graphs. After successfully unifying uncertain graph clustering problem and graph (possible world) coding problem, a novel coded K-means algorithm is proposed.

Download or read book Transactions on Large Scale Data and Knowledge Centered Systems XVIII written by Abdelkader Hameurlain and published by Springer. This book was released on 2015-02-21 with total page 217 pages. Available in PDF, EPUB and Kindle. Book excerpt: The LNCS journal Transactions on Large-Scale Data- and Knowledge-Centered Systems focuses on data management, knowledge discovery, and knowledge processing, which are core and hot topics in computer science. Since the 1990s, the Internet has become the main driving force behind application development in all domains. An increase in the demand for resource sharing across different sites connected through networks has led to an evolution of data- and knowledge-management systems from centralized systems to decentralized systems enabling large-scale distributed applications providing high scalability. Current decentralized systems still focus on data and knowledge as their main resource. Feasibility of these systems relies basically on P2P (peer-to-peer) techniques and the support of agent systems with scaling and decentralized control. Synergy between grids, P2P systems, and agent technologies is the key to data- and knowledge-centered systems in large-scale environments. This, the 18th issue of Transactions on Large-Scale Data- and Knowledge-Centered Systems, contains extended and revised versions of seven papers presented at the 24th International Conference on Database and Expert Systems Applications, DEXA 2013, held in Prague, in the Czech Republic, in August 2013. Following the conference, and two further rounds of reviewing and selection, five extended papers and two invited keynote papers were chosen for inclusion in this special issue. The subject areas covered include argumentation, e-government, business processes, predictive traffic estimation, semantic model integration, top-k query processing, uncertainty handling, graph comparison, community detection, genetic programming, and web services.

Download or read book Uncertain Programming written by Baoding Liu and published by Wiley-Interscience. This book was released on 1999 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: An up-to-date, authoritative, comprehensive look at optimization theory in uncertain environments Real-life management decisions, such as buy/sell decisions in the stock market, are almost always made in uncertain environments. Is it possible to make model decision problems to fit these circumstances? Once constructed, can these models be solved? In Uncertain Programming, Baoding Liu answers both of these questions in the affirmative and goes on to lay a solid foundation for optimization in generally uncertain environments. Uncertain Programming describes the basic concepts of mathematical programming, provides a genetic algorithm for optimization problems, and introduces the techniques of stochastic and fuzzy simulation. After examining some basic results of expected value models, the book moves on to explore chance-constrained programming with stochastic parameters and illustrate applications of chance-constrained programming models. Dr. Liu discusses dependent-chance programming in stochastic environments and extends both chance-constrained and dependent-chance programming from stochastic to fuzzy environments. He then constructs a theoretical framework for fuzzy programming with fuzzy rather than crisp decisions. This remarkable and revolutionary book: * Lays a foundation for optimization theory in uncertain environments * Provides a unifying principle for dealing with stochastic and fuzzy programming * Incorporates the most recent developments in the field * Emphasizes modeling ideas, evolutionary computation, and applications of uncertain programming Uncertain Programming is a reliable, authoritative, and eye-opening guide for researchers and engineers in operations research, management science, business management, information and systems science, and computer science.
