Download or read book Measuring the similarity of charts in graphical statistics written by Krzysztof Gornisiewicz and published by Infinite Study. This book was released on 2024-01-01 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: Figures used in statistics and other sciences play a vital role in understanding and analyzing the problems under study. Due to the complexity and diversity of these problems, figures such as cartograms, choropleth maps, or radar charts take various geometric forms. Their visual evaluation from the view of geometric similarity is essential but insufficient. This paper proposes and theoretically justifies new metrics based on graph theory. They make it possible to quickly determine the degree of similarity of the statistical figures used in the research procedure. The new metrics were used to 1. Determine the similarity of the domestic route networks of major U.S. airlines, 2. Determine the similarity of the distribution of votes cast in U.S. presidential election in each state in 2016 and 2020, 3. Compare radar charts of some countries, constructed based on the Global Competitiveness Index, 4. Analyze the similarity of neutrosophic double line graphs representing sets of approximate (neutrosophic) numbers. This improves analytical capabilities concerning various processes mapped with well-known types of statistical charts, such as choropleth maps, radar charts, etc.

Available in PDF, EPUB and Kindle. Book excerpt: Graphs are mathematical structures used to model objects and their pairwise relationships. Due to their simple but expressive abstract representation, they are commonly used to model various types of relations and processes in technological, social or biological systems and have found numerous applications. A special type of graph is the similarity graph in which nodes represent entities and there is an edge connecting two nodes if the two entities are similar based on some similarity measure. In a typical scenario, raw data of entities are provided in the form of a relational dataset, matrix or a tensor and a similarity graph is built to facilitate graph-based analysis like node importance, node classification, link prediction, community detection, outlier detection, and more. The ability to construct similarity graphs fast is important and with a potential for high impact, thus several approximation techniques have been proposed. In this work, we propose data sketching based methods for fast approximate similarity graph construction. Data sketching techniques are applied on the raw data and are designed to achieve desired error guarantees. They can drastically reduce the size of raw data on which we operate, allowing for faster construction and analysis of similarity graphs, but with approximate results. This is a desirable tradeoff for many applications in diverse domains. Through a thorough experimental evaluation, we demonstrate that our sketching methods outperform sensible baselines and competitor methods proposed for the problem. First, they are much faster than exact methods while maintaining high accuracy in constructing the similarity graph. Furthermore, our methods demonstrate significantly higher accuracy than competitive methods on generic graph analysis tasks. We demonstrate the effectiveness of our methods on different real-world graph applications.

Download or read book Exact and Inexact Methods for Graph Similarity in Structural Pattern Recognition written by Vincenzo Carletti and published by . This book was released on 2016 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: Graphs are widely employed in many application fields, such as biology, chemistry, social networks, databases and so on. Graphs allow to describe a set of objects together with their relationships. Analyzing these data often requires to measure the similarity between two graphs. Unfortunately, due to its combinatorial nature, this is a NP-Complete problem generally addressed using different kind of heuristics. In this Thesis we have explored two approaches to compute the similarity between graphs. The former is based on the exact graph matching approach. We have designed, VF3, an algorithm aimed to search for pattern structures within graphs. While, the second approach is an inexact graph matching method which aims to compute an efficient approximation of the Graph Edit Distance (GED) as a Quadratic Assignment Problem (QAP).

Download or read book Adaptive Graph Walk Based Similarity Measures in Entity relation Graphs written by Einat Minkov and published by . This book was released on 2009 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "Relational or semi-structured data is naturally represented by a graph schema, where nodes denote entities and directed typed edges represent the relations between them. Such graphs are heterogeneous in the sense that they describe different types of objects and multiple types of links. For example, email data can be described in a graph that includes messages, persons, dates and other objects; in this graph, a message may be associated with a person with different relations, such as 'sent-to', 'sent-from' and so on. In the past, researchers have suggested to apply random graph walks in order to elicit a measure of similarity between entities that are not directly connected in a graph. In this thesis, we suggest a general framework, in which different arbitrary queries (for instance, 'what persons are most related to this email message?') are addressed using random walks. Naturally, there are many types of queries possible that correspond to various flavors of inter-entity similarity; several learning techniques are therefore suggested and evaluated that adapt the graph-walk based search to a query type. The framework is applied in the thesis to two different domains. The first domain is personal information management, where it is shown how seemingly different tasks like alias finding, intelligent message threading and person name disambiguation, can be addressed uniformly as search queries using the adaptive graph-walk based similarity measure. The second domain evaluated is the processing of parsed text, where a graph represents corpora of structured parsed text, and adaptive graph walks are applied to induce inter-word similarity measures for tasks such as coordinate term extraction. Finally, design and scalability considerations are discussed."

Download or read book Graph Representation Learning written by William L. William L. Hamilton and published by Springer Nature. This book was released on 2022-06-01 with total page 141 pages. Available in PDF, EPUB and Kindle. Book excerpt: Graph-structured data is ubiquitous throughout the natural and social sciences, from telecommunication networks to quantum chemistry. Building relational inductive biases into deep learning architectures is crucial for creating systems that can learn, reason, and generalize from this kind of data. Recent years have seen a surge in research on graph representation learning, including techniques for deep graph embeddings, generalizations of convolutional neural networks to graph-structured data, and neural message-passing approaches inspired by belief propagation. These advances in graph representation learning have led to new state-of-the-art results in numerous domains, including chemical synthesis, 3D vision, recommender systems, question answering, and social network analysis. This book provides a synthesis and overview of graph representation learning. It begins with a discussion of the goals of graph representation learning as well as key methodological foundations in graph theory and network analysis. Following this, the book introduces and reviews methods for learning node embeddings, including random-walk-based methods and applications to knowledge graphs. It then provides a technical synthesis and introduction to the highly successful graph neural network (GNN) formalism, which has become a dominant and fast-growing paradigm for deep learning with graph data. The book concludes with a synthesis of recent advancements in deep generative models for graphs—a nascent but quickly growing subset of graph representation learning.

Available in PDF, EPUB and Kindle. Book excerpt: An accessible primer on how to create effective graphics from data This book provides students and researchers a hands-on introduction to the principles and practice of data visualization. It explains what makes some graphs succeed while others fail, how to make high-quality figures from data using powerful and reproducible methods, and how to think about data visualization in an honest and effective way. Data Visualization builds the reader’s expertise in ggplot2, a versatile visualization library for the R programming language. Through a series of worked examples, this accessible primer then demonstrates how to create plots piece by piece, beginning with summaries of single variables and moving on to more complex graphics. Topics include plotting continuous and categorical variables; layering information on graphics; producing effective “small multiple” plots; grouping, summarizing, and transforming data for plotting; creating maps; working with the output of statistical models; and refining plots to make them more comprehensible. Effective graphics are essential to communicating ideas and a great way to better understand data. This book provides the practical skills students and practitioners need to visualize quantitative data and get the most out of their research findings. Provides hands-on instruction using R and ggplot2 Shows how the “tidyverse” of data analysis tools makes working with R easier and more consistent Includes a library of data sets, code, and functions
Download or read book Show Me the Numbers written by Stephen Few and published by . This book was released on 2012 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Information, no matter how important, cannot speak for itself. To tell its story, it relies on us to give it a clear voice. No information is more critical than quantitative data ... numbers that reveal what's happening, how our organizations are performing, and opportunities to do better. Numbers are usually presented in tables and graphs, but few are properly designed, resulting not only in poor communication, but at times in miscommunication. This is a travesty, because the skills needed to present quantitative information effectively are simple to learn. Good communication doesn't just happen; it is the result of good design.
