Data mining is a process of discovering patterns in large data sets involving methods at the intersection of machine learning , statistics , and database systems. The term "data mining" is a misnomer , because the goal is the extraction of patterns and knowledge from large amounts of data, not the extraction mining of data itself. The book Data mining: Practical machine learning tools and techniques with Java [8] which covers mostly machine learning material was originally to be named just Practical machine learning , and the term data mining was only added for marketing reasons.

This book explores the concepts of data mining and data warehousing, a promising and flourishing frontier in data base systems and new data base applications and is also designed to give a broad, yet in-depth overview of the field of data mining. Data mining is a multidisciplinary field, drawing work from areas including database technology, AI, machine learning, NN, statistics, pattern recognition, knowledge based systems, knowledge acquisition, information retrieval, high performance computing and data visualization. This book is intended for a wide audience of readers who are not necessarily experts in data warehousing and data mining, but are interested in receiving a general introduction to these areas and their many practical applications. Since data mining technology has become a hot topic not only among academic students but also for decision makers, it provides valuable hidden business and scientific intelligence from a large amount of historical data. It is also written for technical managers and executives as well as for technologists interested in learning about data mining.

Introduction to Data Warehousing

A Data Warehousing DW is process for collecting and managing data from varied sources to provide meaningful business insights. A Data warehouse is typically used to connect and analyze business data from heterogeneous sources. The data warehouse is the core of the BI system which is built for data analysis and reporting. It is a blend of technologies and components which aids the strategic use of data. It is electronic storage of a large amount of information by a business which is designed for query and analysis instead of transaction processing. It is a process of transforming data into information and making it available to users in a timely manner to make a difference.

Data mining is the process of nontrivial extraction of implicit, previously unknown and potentially useful information from the raw data present in the large database Jiawei et al. Data mining techniques can be applied upon various data sources to improve the value of the existing information system. When implemented on high performance client and server system, data mining tools can analyze large databases to deliver highly reliable results. It is also described that the data mining techniques can be coupled with relational database engines Jiawei et al. Data mining differs from the conventional database retrieval in the fact that it extracts hidden information or knowledge that is not explicitly available in the database, whereas database retrieval extracts the data that is explicitly available in the databases through some query language. Based on the fact that, a certain degree of intelligence is incorporated in the system, data mining could further be viewed as a branch of artificial intelligence and thus, it could be treated as an intelligent database manipulation system.

This book explores the concepts of data mining and data warehousing, a promising and flourishing frontier in data base systems and new data base applications and is also designed to give a broad, yet in-depth overview of the field of data mining.

Avoiding False Discoveries: A completely new addition in the second edition is a chapter on how to avoid false discoveries and produce valid results, which is novel among other contemporary textbooks on data mining. It supplements the discussions in the other chapters with a discussion of the statistical concepts statistical significance, p-values, false discovery rate, permutation testing, etc. This chapter addresses the increasing concern over the validity and reproducibility of results obtained from data analysis. The addition of this chapter is a recognition of the importance of this topic and an acknowledgment that a deeper understanding of this area is needed for those analyzing data. Classification: Some of the most significant improvements in the text have been in the two chapters on classification.

 - Я должен выполнять свои обязанности. Он поднял телефонную трубку и набрал номер круглосуточно включенного мобильника Джаббы. ГЛАВА 45 Дэвид Беккер бесцельно брел по авенида дель Сид, тщетно пытаясь собраться с мыслями. На брусчатке под ногами мелькали смутные тени, водка еще не выветрилась из головы. Все происходящее напомнило ему нечеткую фотографию. Мысли его то и дело возвращались к Сьюзан: он надеялся, что она уже прослушала его голос на автоответчике.

Стратмор нахмурился: - В этом вся проблема. - Офицер полиции этого не знает. - Не имеет понятия. Рассказ канадца показался ему полным абсурдом, и он подумал, что старик еще не отошел от шока или страдает слабоумием. Тогда он посадил его на заднее сиденье своего мотоцикла, чтобы отвезти в гостиницу, где тот остановился. Но этот канадец не знал, что ему надо держаться изо всех сил, поэтому они и трех метров не проехали, как он грохнулся об асфальт, разбил себе голову и сломал запястье.

Вот мои условия. Ты даешь мне ключ. Если Стратмор обошел фильтры, я вызываю службу безопасности. Если я ошиблась, то немедленно ухожу, а ты можешь хоть с головы до ног обмазать вареньем свою Кармен Хуэрту.

 Как прикажете это понимать. На лице Стратмора тут же появилось виноватое выражение. Он улыбнулся, стараясь ее успокоить.

Резким движением Халохот развернул безжизненное тело и вскрикнул от ужаса. Перед ним был не Дэвид Беккер. Рафаэль де ла Маза, банкир из пригорода Севильи, скончался почти мгновенно. Рука его все еще сжимала пачку банкнот, пятьдесят тысяч песет, которые какой-то сумасшедший американец заплатил ему за дешевый черный пиджак.

Она с самого начала возражала против его кандидатуры, но АНБ посчитало, что другого выхода. Хейл появился в порядке возмещения ущерба. После фиаско Попрыгунчика. Четыре года назад конгресс, стремясь создать новый стандарт шифрования, поручил лучшим математикам страны, иными словами - сотрудникам АНБ, написать новый супералгоритм. Конгресс собирался принять закон, объявляющий этот новый алгоритм национальным стандартом, что должно было решить проблему несовместимости, с которой сталкивались корпорации, использующие разные алгоритмы.
