Book Synopsis Kernel Methods for Pattern Analysis by : John Shawe-Taylor
Download or read book Kernel Methods for Pattern Analysis written by John Shawe-Taylor and published by Cambridge University Press. This book was released on 2004-06-28 with total page 520 pages. Available in PDF, EPUB and Kindle. Book excerpt: Kernel methods provide a powerful and unified framework for pattern discovery, motivating algorithms that can act on general types of data (e.g. strings, vectors or text) and look for general types of relations (e.g. rankings, classifications, regressions, clusters). The application areas range from neural networks and pattern recognition to machine learning and data mining. This book, developed from lectures and tutorials, fulfils two major roles: firstly it provides practitioners with a large toolkit of algorithms, kernels and solutions ready to use for standard pattern discovery problems in fields such as bioinformatics, text analysis, image analysis. Secondly it provides an easy introduction for students and researchers to the growing field of kernel-based pattern analysis, demonstrating with examples how to handcraft an algorithm or a kernel for a new specific application, and covering all the necessary conceptual and mathematical tools to do so.
Book Synopsis Multivariate Time Series Clustering Using Kernel Variant Multi-way Principal Component Analysis by : Hwanseok Choi
Download or read book Multivariate Time Series Clustering Using Kernel Variant Multi-way Principal Component Analysis written by Hwanseok Choi and published by . This book was released on 2010 with total page 115 pages. Available in PDF, EPUB and Kindle. Book excerpt: Clustering multivariate time series data has been a challenging task for researchers since data has multiple dimensions to consider such as auto-correlations and cross-correlations whereas multivariate time series data has been prevailing in diverse areas for decades. However, for a short-period time series data, conventional time series modeling may not satisfy the model validity. Multi-way Principal Component Analysis can be used for this case, but the normality assumption can restrict to handle nonlinear data such as multivariate time series with high order interactions. Kernel variant MPCA will be proposed for an alternative solution for this case. To test if KMPCA can cluster trivariate time series data into two groups, two simulation studies were conducted. The first study has the same mean structure groups with error structures which are combinations of three different auto-correlation levels and three different cross-correlation levels. Two different mean structure groups with nine error structures were generated for the second study. To check the proposed method work well on a real-world data, Obesity-depression relationship study was done for a real-world data. The simulation studies showed that KMPCA cluster two different mean structure groups over 90% success rates when an appropriate kernel function with proper parameter was applied. Similar error structure will obstruct the clustering performance: strong cross-correlation, weak auto-correlation, and larger number of temporal points. Considering racial effect, obesity and obesity related variables, especially addictive material uses for 15 years can expect depressed cohorts at year 20 up to 76% for Caucasian group and 95% for African-American group.

Book Synopsis Gaussian Processes for Machine Learning by : Carl Edward Rasmussen
Download or read book Gaussian Processes for Machine Learning written by Carl Edward Rasmussen and published by MIT Press. This book was released on 2005-11-23 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive and self-contained introduction to Gaussian processes, which provide a principled, practical, probabilistic approach to learning in kernel machines. Gaussian processes (GPs) provide a principled, practical, probabilistic approach to learning in kernel machines. GPs have received increased attention in the machine-learning community over the past decade, and this book provides a long-needed systematic and unified treatment of theoretical and practical aspects of GPs in machine learning. The treatment is comprehensive and self-contained, targeted at researchers and students in machine learning and applied statistics. The book deals with the supervised-learning problem for both regression and classification, and includes detailed algorithms. A wide variety of covariance (kernel) functions are presented and their properties discussed. Model selection is discussed both from a Bayesian and a classical perspective. Many connections to other well-known techniques from machine learning and statistics are discussed, including support-vector machines, neural networks, splines, regularization networks, relevance vector machines and others. Theoretical issues including learning curves and the PAC-Bayesian framework are treated, and several approximation methods for learning with large datasets are discussed. The book contains illustrative examples and exercises, and code and datasets are available on the Web. Appendixes provide mathematical background and a discussion of Gaussian Markov processes.
Book Synopsis Kernel Methods in the Analysis of Big and Complex Data by : Hao Zhou
Download or read book Kernel Methods in the Analysis of Big and Complex Data written by Hao Zhou and published by . This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Kernel methods have achieved a lot of success in statistics and machine learning where linear models are often not sufficient to capture the relations and patterns in the data. For example, in smoothing spline models, a kernel is used to define a non-parametric class of the function so that one can fit a smoothing curve or surface to understand the relation between the response and predictors. Similarly, in Gaussian process, a kernel is used to define the covariance matrix so that one can understand the nonlinear trend of the data in a Bayesian manner. In support vector machine, a kernel is used to define a non-linear map to transform the predictors into a high-dimensional space so that one can find a hyperplane in the new space to distinguish data from different classes. All these methods over the past two decades have been successful in applications for biomedical science, finance, pattern recognition, and recommender systems. In modern data analysis, we occasionally face a number of interesting chal- lenges: our data may come from multiple heterogeneous sources, our data may be spatiotemporal, have few samples but lie in high dimensions, or our data may have a huge number of samples and require a method to understand the complex model. These challenges require us to consider new developments in statistics and kernel methods. In this work, we show how kernel methods can help us solve these challenges with other topics including domain adaptation, regularized statistics, deep learning, and deep Gaussian processes. In Chapter 2, we study the problem of analyzing data from multiple heteroge- neous sources. We derive a framework with a graphical causal model and maximum mean discrepancy to eliminate the biases between different datasets and to com- bine multiple datasets together in a systematic way for increased sample size and for improved statistical power. We use the framework for a problem motivated by Alzheimer's Disease research and show that we can successfully combine two datasets from different research centers to derive more accurate and consistent results. In Chapter 3, we continue our study on the problem of the analysis of multiple heterogeneous datasets but with a different focus. We derive new hypothesis tests and theoretical analysis to understand when it is beneficial to combine multiple datasets together, both in the low dimension setting and high dimension setting. We find that the problem is a bias-variance trade-off. When the reduction on the variance, which may due to increased sample size, is more than the increase on the bias from heterogeneous datasets, it is beneficial to combine different datasets even though they come from different sources. In Chapter 4, we study how to build a nonparametric model for spatiotemporal data when the samples are few but the dimension is high. We apply the frame- work on a Chicago crime dataset to understand the occurrence of crimes and it's transmission between various Chicago communities as time goes. The multiple communities and nonparametric kernel class make our model lie in high dimension but the limited crime events make our sample size small. We solve the problem by adding regularizations for the kernel-based models and we build a solid theo- retical foundation to understand the behavior of our models for high-dimensional spatiotemporal data. Finally, in Chapter 5, we propose a framework to understand the flow of the information in deep probabilistic models, which includes Bayesian neural networks, deep Gaussian processes, deep kernel learning, and others. On the one hand, we show that we can understand the information flow in deep probabilistic models using kernels and statistical structure assumptions and we show the relation be- tween Bayesian neural networks and deep Gaussian processes through theoretical analysis. On the other hand, our framework points out a way to extend additive models, hierarchical models and other statistical models with structure assump- tions to the deep structure so that we can use modern high computation power like deep learning while maintaining the good properties of statistical models including interpretability and uncertainty estimate.

Book Synopsis Robust Kernel Methods in Context-dependent Fusion by : Gyeongyong Heo
Download or read book Robust Kernel Methods in Context-dependent Fusion written by Gyeongyong Heo and published by . This book was released on 2009 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: By adding the regularization terms, not only does CDF-R achieve noise robustness, the main purpose of regularization, but the consequent clusters, which need not be convex, result in better performance than CDF. Although CDF-R is better at classification than CDF, the linear separability does not change. To completely remove the limitation, CDF is transformed to be non-linear, termed kernel-based context-dependent fusion (K-CDF). K-CDF adopts modified kernel methods to remove the restrictions of CDF and remedies some problems in the original kernel methods. K-CDF consists of three main components: dimension reduction, feature space clustering, and fusion. For each component, robust kernel fuzzy principal component analysis (RKF-PCA), kernel-based global fuzzy c-means (KG-FCM), and fuzzy support vector machine for noisy data (FSVM-N) are formulated, and which correspond to the robust variant of kernel PCA, kernel FCM, and fuzzy SVM, respectively. Although the three modifications were originated to address different shortcomings, one common purpose is to reduce the effect of nose, i.e., making the kernel methods noise-robust. By combining the three robust kernel methods, not only does K-CDF overcome the convex cluster assumption and linearly separable restriction, but it achieves noise robustness and better performance than previous methods.

Book Synopsis Multivariate Kernel Smoothing and Its Applications by : José E. Chacón
Download or read book Multivariate Kernel Smoothing and Its Applications written by José E. Chacón and published by CRC Press. This book was released on 2018-05-08 with total page 255 pages. Available in PDF, EPUB and Kindle. Book excerpt: Kernel smoothing has greatly evolved since its inception to become an essential methodology in the data science tool kit for the 21st century. Its widespread adoption is due to its fundamental role for multivariate exploratory data analysis, as well as the crucial role it plays in composite solutions to complex data challenges. Multivariate Kernel Smoothing and Its Applications offers a comprehensive overview of both aspects. It begins with a thorough exposition of the approaches to achieve the two basic goals of estimating probability density functions and their derivatives. The focus then turns to the applications of these approaches to more complex data analysis goals, many with a geometric/topological flavour, such as level set estimation, clustering (unsupervised learning), principal curves, and feature significance. Other topics, while not direct applications of density (derivative) estimation but sharing many commonalities with the previous settings, include classification (supervised learning), nearest neighbour estimation, and deconvolution for data observed with error. For a data scientist, each chapter contains illustrative Open data examples that are analysed by the most appropriate kernel smoothing method. The emphasis is always placed on an intuitive understanding of the data provided by the accompanying statistical visualisations. For a reader wishing to investigate further the details of their underlying statistical reasoning, a graduated exposition to a unified theoretical framework is provided. The algorithms for efficient software implementation are also discussed. José E. Chacón is an associate professor at the Department of Mathematics of the Universidad de Extremadura in Spain. Tarn Duong is a Senior Data Scientist for a start-up which provides short distance carpooling services in France. Both authors have made important contributions to kernel smoothing research over the last couple of decades.
Book Synopsis Frontiers in Massive Data Analysis by : National Research Council
Download or read book Frontiers in Massive Data Analysis written by National Research Council and published by National Academies Press. This book was released on 2013-09-03 with total page 191 pages. Available in PDF, EPUB and Kindle. Book excerpt: Data mining of massive data sets is transforming the way we think about crisis response, marketing, entertainment, cybersecurity and national intelligence. Collections of documents, images, videos, and networks are being thought of not merely as bit strings to be stored, indexed, and retrieved, but as potential sources of discovery and knowledge, requiring sophisticated analysis techniques that go far beyond classical indexing and keyword counting, aiming to find relational and semantic interpretations of the phenomena underlying the data. Frontiers in Massive Data Analysis examines the frontier of analyzing massive amounts of data, whether in a static database or streaming through a system. Data at that scale-terabytes and petabytes-is increasingly common in science (e.g., particle physics, remote sensing, genomics), Internet commerce, business analytics, national security, communications, and elsewhere. The tools that work to infer knowledge from data at smaller scales do not necessarily work, or work well, at such massive scale. New tools, skills, and approaches are necessary, and this report identifies many of them, plus promising research directions to explore. Frontiers in Massive Data Analysis discusses pitfalls in trying to infer knowledge from massive data, and it characterizes seven major classes of computation that are common in the analysis of massive data. Overall, this report illustrates the cross-disciplinary knowledge-from computer science, statistics, machine learning, and application disciplines-that must be brought to bear to make useful inferences from massive data.
