Download or read book Analysis of Rare Categories written by Jingrui He and published by Springer Science & Business Media. This book was released on 2012-01-05 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: In many real-world problems, rare categories (minority classes) play essential roles despite their extreme scarcity. The discovery, characterization and prediction of rare categories of rare examples may protect us from fraudulent or malicious behavior, aid scientific discovery, and even save lives. This book focuses on rare category analysis, where the majority classes have smooth distributions, and the minority classes exhibit the compactness property. Furthermore, it focuses on the challenging cases where the support regions of the majority and minority classes overlap. The author has developed effective algorithms with theoretical guarantees and good empirical results for the related techniques, and these are explained in detail. The book is suitable for researchers in the area of artificial intelligence, in particular machine learning and data mining.
Download or read book Big Visual Data Analysis written by Chen Chen and published by Springer. This book was released on 2016-02-24 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers an overview of traditional big visual data analysis approaches and provides state-of-the-art solutions for several scene comprehension problems, indoor/outdoor classification, outdoor scene classification, and outdoor scene layout estimation. It is illustrated with numerous natural and synthetic color images, and extensive statistical analysis is provided to help readers visualize big visual data distribution and the associated problems. Although there has been some research on big visual data analysis, little work has been published on big image data distribution analysis using the modern statistical approach described in this book. By presenting a complete methodology on big visual data analysis with three illustrative scene comprehension problems, it provides a generic framework that can be applied to other big visual data analysis tasks.
Download or read book Categorical Data Analysis by Example written by Graham J. G. Upton and published by John Wiley & Sons. This book was released on 2016-11-14 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: Introduces the key concepts in the analysis of categoricaldata with illustrative examples and accompanying R code This book is aimed at all those who wish to discover how to analyze categorical data without getting immersed in complicated mathematics and without needing to wade through a large amount of prose. It is aimed at researchers with their own data ready to be analyzed and at students who would like an approachable alternative view of the subject. Each new topic in categorical data analysis is illustrated with an example that readers can apply to their own sets of data. In many cases, R code is given and excerpts from the resulting output are presented. In the context of log-linear models for cross-tabulations, two specialties of the house have been included: the use of cobweb diagrams to get visual information concerning significant interactions, and a procedure for detecting outlier category combinations. The R code used for these is available and may be freely adapted. In addition, this book: Uses an example to illustrate each new topic in categorical data Provides a clear explanation of an important subject Is understandable to most readers with minimal statistical and mathematical backgrounds Contains examples that are accompanied by R code and resulting output Includes starred sections that provide more background details for interested readers Categorical Data Analysis by Example is a reference for students in statistics and researchers in other disciplines, especially the social sciences, who use categorical data. This book is also a reference for practitioners in market research, medicine, and other fields.

Download or read book Rare Category Analysis written by Jingrui He and published by . This book was released on 2010 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "In many real world problems, rare categories (minority classes) play an essential role despite of their extreme scarcity. For example, in financial fraud detection, the vast majority of the financial transactions are legitimate, and only a small number may be fraudulent; in Medicare fraud detection, the percentage of bogus claims is small, but the total loss is significant; in network intrusion detection, malicious network activities are hidden among huge volumes of routine network traffic; in astronomy, only 0.001% of the objects in sky survey images are truly beyond the scope of current science and may lead to new discoveries; in spam image detection, the near-duplicate spam images are difficult to discover from the large number of non-spam image; in rare disease diagnosis, the rare diseases affect less than 1 out of 2000 people, but the consequences can be very severe. Therefore, the discovery, characterization and prediction of rare categories or rare examples may protect us from fraudulent or malicious behaviors, provide the aid for scientific discoveries, and even save lives. This thesis focuses on rare category analysis, where the majority classes have a smooth distribution, and the minority classes exhibit a compactness property. Furthermore, we focus on the challenging cases where the support regions of the majority and minority classes overlap each other. To the best of our knowledge, this thesis is the first end-to-end investigation of rare categories. Depending on the availability of the label information, we can perform either supervised or unsupervised rare category analysis. In the supervised settings, our first task is rare category detection, which is to discover at least one example from each minority class with the help of a labeling oracle. Then given labeled examples from all the classes, our second task is rare category characterization. The goal here is to find a compact representation for the minority classes in order to identify all the rare examples with high precision and recall. On the other hand, in the unsupervised settings, we do not have access to a labeling oracle. Here we propose to co-select candidate examples from the minority classes and the relevant features, which benefits both tasks (rare category selection and feature selection). For each of the above tasks, we have developed effective algorithms with theoretical guarantees as well as good empirical results. In the future, we plan to apply rare category analysis on rich data, such as medical images, texts / blogs, Electronic Health Records (EHR), web link graphs, stream data, etc; we plan to build statistical models for the rare categories in order to understand how they emerge and evolve over time; we plan to study complex fraud based on rare category analysis; we plan to make use of transfer learning to help with our analysis; we also plan to build a complete system for rare category analysis."

Download or read book Beginning Data Science with R written by Manas A. Pathak and published by Springer. This book was released on 2014-12-08 with total page 165 pages. Available in PDF, EPUB and Kindle. Book excerpt: “We live in the age of data. In the last few years, the methodology of extracting insights from data or "data science" has emerged as a discipline in its own right. The R programming language has become one-stop solution for all types of data analysis. The growing popularity of R is due its statistical roots and a vast open source package library. The goal of “Beginning Data Science with R” is to introduce the readers to some of the useful data science techniques and their implementation with the R programming language. The book attempts to strike a balance between the how: specific processes and methodologies, and understanding the why: going over the intuition behind how a particular technique works, so that the reader can apply it to the problem at hand. This book will be useful for readers who are not familiar with statistics and the R programming language.

Download or read book Confronting Capital Punishment in Asia written by Roger Hood and published by OUP Oxford. This book was released on 2013-11-07 with total page 1282 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the strengthening focus worldwide on human rights, there has been a rapid increase in recent years in the number of countries that have completely abolished the death penalty. This is in recognition that it is a violation of the right to life and the right to be free from cruel, inhuman and degrading punishment. There has, simultaneously, been pressure on countries that still retain capital punishment to ensure that they at least apply the United Nations minimum human rights safeguards established to protect the rights of those facing the death penalty. This book shows that the majority of Asian countries have been particularly resistant to the abolitionist movement and tardy in accepting their responsibility to uphold the safeguards. The essays contained in this volume provide an in-depth analysis of changes in the scope and application of the death penalty in Asia with a focus on China, India, Japan, and Singapore. They explain the extent to which these nations still fail to accept capital punishment as a human rights issue, identify impediments to reform, and explore the prospects that Asian countries will eventually embrace the goal of worldwide abolition of capital punishment.

Download or read book Early Intervention in Psychotic Disorders written by Tandy Miller and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: Multiple voices throughout the last century have preached the merits of various treatments for schizophrenia, ranging from cold baths to the currently accepted standards such as neuroleptic medication. Along with these ongoing treatments, there have been quiet commentaries, made mostly from the sidelines, suggesting the need to shift and refocus the way we think and talk about schizophrenia. Harry Stack Sullivan noted in 1927 that, 'The psychiatrist sees too many end states and deals professionally with too few of the pre psychotic" (Sullivan 192711994, p. 135). Similar thoughts have been echoed by purveyors of modem treatment for psychosis such as Thomas H. McGlashan: "Like others before me, I tried to make a difference . . . but like the others my efforts were largely in vain. I came upon the scene too late; most of the damage was already done" (McGlashan, 1996). Similar interest in the early phase of schizophrenia has developed across the globe and consolidated into a tentative, yet meaningful deliberation about the potential for prevention of psychotic illness through early identification and intervention. In the past decade, international support has grown from: Ian Falloon's prodromal intervention project in Great Britain (Falloon et aI. , 1996); Patrick McGorry's and Jane Edward's first episode psychosis program in Melbourne, Australia (McGorry et al.
Download or read book Cochrane Handbook for Systematic Reviews of Interventions written by Julian P. T. Higgins and published by Wiley. This book was released on 2008-11-24 with total page 672 pages. Available in PDF, EPUB and Kindle. Book excerpt: Healthcare providers, consumers, researchers and policy makers are inundated with unmanageable amounts of information, including evidence from healthcare research. It has become impossible for all to have the time and resources to find, appraise and interpret this evidence and incorporate it into healthcare decisions. Cochrane Reviews respond to this challenge by identifying, appraising and synthesizing research-based evidence and presenting it in a standardized format, published in The Cochrane Library (www.thecochranelibrary.com). The Cochrane Handbook for Systematic Reviews of Interventions contains methodological guidance for the preparation and maintenance of Cochrane intervention reviews. Written in a clear and accessible format, it is the essential manual for all those preparing, maintaining and reading Cochrane reviews. Many of the principles and methods described here are appropriate for systematic reviews applied to other types of research and to systematic reviews of interventions undertaken by others. It is hoped therefore that this book will be invaluable to all those who want to understand the role of systematic reviews, critically appraise published reviews or perform reviews themselves.
