Download or read book Learning from Imbalanced Data Sets written by Alberto Fernández and published by Springer. This book was released on 2018-10-22 with total page 377 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a general and comprehensible overview of imbalanced learning. It contains a formal description of a problem, and focuses on its main features, and the most relevant proposed solutions. Additionally, it considers the different scenarios in Data Science for which the imbalanced classification can create a real challenge. This book stresses the gap with standard classification tasks by reviewing the case studies and ad-hoc performance metrics that are applied in this area. It also covers the different approaches that have been traditionally applied to address the binary skewed class distribution. Specifically, it reviews cost-sensitive learning, data-level preprocessing methods and algorithm-level solutions, taking also into account those ensemble-learning solutions that embed any of the former alternatives. Furthermore, it focuses on the extension of the problem for multi-class problems, where the former classical methods are no longer to be applied in a straightforward way. This book also focuses on the data intrinsic characteristics that are the main causes which, added to the uneven class distribution, truly hinders the performance of classification algorithms in this scenario. Then, some notes on data reduction are provided in order to understand the advantages related to the use of this type of approaches. Finally this book introduces some novel areas of study that are gathering a deeper attention on the imbalanced data issue. Specifically, it considers the classification of data streams, non-classical classification problems, and the scalability related to Big Data. Examples of software libraries and modules to address imbalanced classification are provided. This book is highly suitable for technical professionals, senior undergraduate and graduate students in the areas of data science, computer science and engineering. It will also be useful for scientists and researchers to gain insight on the current developments in this area of study, as well as future research directions.

Download or read book Multiple Fuzzy Classification Systems written by Rafał Scherer and published by Springer. This book was released on 2012-06-26 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fuzzy classifiers are important tools in exploratory data analysis, which is a vital set of methods used in various engineering, scientific and business applications. Fuzzy classifiers use fuzzy rules and do not require assumptions common to statistical classification. Rough set theory is useful when data sets are incomplete. It defines a formal approximation of crisp sets by providing the lower and the upper approximation of the original set. Systems based on rough sets have natural ability to work on such data and incomplete vectors do not have to be preprocessed before classification. To achieve better performance than existing machine learning systems, fuzzy classifiers and rough sets can be combined in ensembles. Such ensembles consist of a finite set of learning models, usually weak learners. The present book discusses the three aforementioned fields – fuzzy systems, rough sets and ensemble techniques. As the trained ensemble should represent a single hypothesis, a lot of attention is placed on the possibility to combine fuzzy rules from fuzzy systems being members of classification ensemble. Furthermore, an emphasis is placed on ensembles that can work on incomplete data, thanks to rough set theory. .

Download or read book Fuzzy Rough Set Approximations in Large Scale Information Systems written by Hasan Asfoor and published by . This book was released on 2015 with total page 111 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rough set theory is a popular and powerful machine learning tool. It is especially suitable for dealing with information systems that exhibit inconsistencies, i.e. objects that have the same values for the conditional attributes but a different value for the decision attribute. In line with the emerging granular computing paradigm, rough set theory groups objects together based on the indiscernibility of their attribute values. Fuzzy rough set theory extends rough set theory to data with continuous attributes, and detects degrees of inconsistency in the data. Key to this is turning the indiscernibility relation into a gradual relation, acknowledging that objects can be similar to a certain extent. In very large datasets with millions of objects, computing the gradual indiscernibility relation (or in other words, the soft granules) is very demanding, both in terms of runtime and in terms of memory. It is however required for the computation of the lower and upper approximations of concepts in the fuzzy rough set analysis pipeline. In this thesis, we present a parallel and distributed solution implemented on both Apache Spark and Message Passing Interface (MPI) to compute fuzzy rough approximations in very large information systems. Our results show that our parallel approach scales with problem size to information systems with millions of objects. To the best of our knowledge, no other parallel and distributed solutions have been proposed so far in the literature for this problem. We also present two distributed prototype selection approaches that are based on fuzzy rough set theory and couple them with our distributed implementation of the well known weighted k-nearest neighbors machine learning prediction technique to solve regression problems. In addition, we show how our distributed approaches can be used on the State Inpatient Data Set (SID) and the Medical Expenditure Panel Survey (MEPS) to predict the total healthcare expenses of patients.

Download or read book Fuzzy Rough Approaches for Pattern Classification written by Rajen Bhatt and published by . This book was released on 2017-08-29 with total page 265 pages. Available in PDF, EPUB and Kindle. Book excerpt: The primary objective of any supervised learning technique is to learn an unknown function (or at least a good approximation of it) from a set of observed input-output patterns. Pattern classification is a special case of function approximation, where each pattern is assigned to a particular class, i.e., the output in classification problem is one of the discrete values corresponding to class rather than real-valued function in regression. Precisely, in a classification problem output belongs to one of the discrete classes, while in a regression problem output belongs to a set of real number R. This book discuss various fuzzy-rough approach to pattern classification, and develops some hybrid measures and algorithms for attribute (or feature) selection and induction of fuzzy decision trees. Hybrid fuzzy-rough algorithms derive best benefits of both the worlds; fuzzy systems and rough sets theory. Fuzzy systems are well known for their ability to handle vagueness in the data. On the other hand, rough sets are pure data driven knowledge discovery tools capable of handling ambiguity very well by various approximations. In general, vagueness is related to the difficulty in making sharp classification boundaries. Ambiguity is associated with one-to-many mapping. This book develops feature selection and pattern classification models which take care of these two inherent problems associated with knowledge discovery from data. Many interesting properties of the developed fuzzy-rough measures are derived and their importance from pattern classification view point is shown. Later it is shown that how neural type of learning algorithms can be integrated in fuzzy decision tree induction technique to improve their learning accuracy. Neural learning is introduced by two ways; first by transforming fuzzy decision tree structure in the equivalent Gaussian radial basis function (RBF) structure and second by directly applying back-propagation gradient descent learning algorithm on the structure of fuzzy decision trees. Former technique provide a novel solution for initialization of structure and parameters of Gaussian RBF network and later technique build novel neuro-fuzzy models known as Neuro-Fuzzy Decision Trees. It is shown that how fuzzy decision trees are functionally equivalent to Gaussian RBF networks and this equivalence is used to establish a mapping from one fuzzy decision trees to Gaussian RBF networks and vice versa. Such mappings allow applying various gradient descent type of learning algorithms to the mapped Gaussian RBF network structure and improve classification accuracy of the model. It is shown that how fuzzy decision trees' classification accuracy is improved after mapping to Gaussian RBF network and how the structure of fuzzy decision trees are changing after mapping back from Gaussian RBF network structure. This leads to an interesting discussion about destructive and non-destructive type of learning algorithms. Later it is shown that how Neuro-fuzzy decision trees are keeping the structure of fuzzy decision trees intact and still improve their learning accuracy. All the proposed algorithms have been stated explicitly in the formal notation and in pseudo code format. Extensive computational experiments have been reported and the proposed algorithms have been experimentally compared with well-known algorithms from the literature using real-world standard datasets. Readers will also find literature review of rough sets and fuzzy decision trees very useful, especially classification of fuzzy decision tree literature in six different categories, rough sets fundamentals and applications of fuzzy decision trees and rough sets theory in many domains.

Download or read book How Fuzzy Concepts Contribute to Machine Learning written by Mahdi Eftekhari and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book introduces some contemporary approaches on the application of fuzzy and hesitant fuzzy sets in machine learning tasks such as classification, clustering and dimension reduction. Many situations arise in machine learning algorithms in which applying methods for uncertainty modeling and multi-criteria decision making can lead to a better understanding of algorithms behavior as well as achieving good performances. Specifically, the present book is a collection of novel viewpoints on how fuzzy and hesitant fuzzy concepts can be applied to data uncertainty modeling as well as being used to solve multi-criteria decision making challenges raised in machine learning problems. Using the multi-criteria decision making framework, the book shows how different algorithms, rather than human experts, are employed to determine membership degrees. The book is expected to bring closer the communities of pure mathematicians of fuzzy sets and data scientists. .
