Data mining includes the utilization of refined data analysis tools to find previously unknown, valid patterns and relationships in huge data sets.

This chapter describes the predictive models, that is, the supervised learning functions. These functions predict a target value. The Oracle Data Mining Java interface supports the following predictive functions and associated algorithms:. In a classification problem, you typically have historical data labeled examples and unlabeled examples. Each labeled example consists of multiple predictor attributes and one target attribute dependent variable.

Data mining functionalities are used to specify the kind of patterns to be found in data mining tasks. Data mining tasks can be classified into two categories: descriptive and predictive. Data can be associated with classes or concepts. For example, in the Electronics store, classes of items for sale include computers and printers, and concepts of customers include bigSpenders and budgetSpenders. Data characterization is a summarization of the general characteristics or features of a target class of data. Data discrimination is a comparison of the general features of target class data objects with the general features of objects from one or a set of contrasting classes.

Data Mining is a process of finding potentially useful patterns from huge data sets. It is a multi-disciplinary skill that uses machine learning , statistics, and AI to extract information to evaluate future events probability. The insights derived from Data Mining are used for marketing, fraud detection, scientific discovery, etc. Data Mining is all about discovering hidden, unsuspected, and previously unknown yet valid relationships amongst the data. First, you need to understand business and client objectives.

Data Mining Techniques

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. The actual data mining task is the semi-automatic or automatic analysis of large quantities of data to extract previously unknown, interesting patterns such as groups of data records cluster analysis , unusual records anomaly detection , and dependencies association rule mining , sequential pattern mining. This usually involves using database techniques such as spatial indices. These patterns can then be seen as a kind of summary of the input data, and may be used in further analysis or, for example, in machine learning and predictive analytics. For example, the data mining step might identify multiple groups in the data, which can then be used to obtain more accurate prediction results by a decision support system.

Потом, тяжело вздохнув, скомандовал: - Хорошо. Запускайте видеозапись. ГЛАВА 117 - Трансляция видеофильма начнется через десять секунд, - возвестил трескучий голос агента Смита.  - Мы опустим каждый второй кадр вместе со звуковым сопровождением и постараемся держаться как можно ближе к реальному времени. На подиуме все замолчали, не отрывая глаз от экрана.

 Venti mille pesete. La Vespa. - Cinquanta mille. Пятьдесят тысяч! - предложил Беккер. Это почти четыреста долларов. Итальянец засмеялся. Он явно не верил своим ушам.

Ему захотелось увидеть ее глаза, он надеялся найти в них избавление. Но в них была только смерть. Смерть ее веры в. Любовь и честь были забыты. Мечта, которой он жил все эти годы, умерла.

 Меган! - завопил он, грохнувшись на пол. Острые раскаленные иглы впились в глазницы. Он уже ничего не видел и только чувствовал, как тошнотворный комок подкатил к горлу. Его крик эхом отозвался в черноте, застилавшей. Беккер не знал, сколько времени пролежал, пока над ним вновь не возникли лампы дневного света.

 Отпусти. - Мне нужен ключ, - повторила Сьюзан.

Он несколько раз моргнул затуманенными глазами, надеясь, что это лишь галлюцинация. Увы, ангар был пуст. О Боже.

 Да, - сказал Фонтейн, - и двадцать четыре часа в сутки наши фильтры безопасности их туда не пускают.

Стратмор был блестящим специалистом, возможно, лучшим в агентстве. И в то же время после провала с Попрыгунчиком Стратмор испытывал колоссальный стресс. Это беспокоило Фонтейна: к коммандеру сходится множество нитей в агентстве, а директору нужно оберегать свое ведомство.
