Chapter 1 Data Mining In this intoductory chapter we begin with the essence of data mining and a dis-cussion of how data mining is treated by …. Various issues in performance are being regarded a large overhead in Data extraction.

Data Mining Concepts

The ability to predict the performance tendency of students is very important to improve their teaching skills. It has become a valuable knowledge that can be used for different purposes; for example, a strategic plan can be applied for the development of a quality education. This paper proposes the application of data mining techniques to predict the final grades of students based on their historical data. In the experimental studies, three well-known data mining techniques decision tree, random forest, and naive Bayes were employed on two educational datasets related to mathematics lesson and Portuguese language lesson. The results showed the effectiveness of data mining learning techniques when predicting the performances of students. Data Mining - Methods, Applications and Systems.

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.

Data mining

There are two forms of data analysis that can be used for extracting models describing important classes or to predict future data trends. Classification models predict categorical class labels; and prediction models predict continuous valued functions. For example, we can build a classification model to categorize bank loan applications as either safe or risky, or a prediction model to predict the expenditures in dollars of potential customers on computer equipment given their income and occupation. A bank loan officer wants to analyze the data in order to know which customer loan applicant are risky or which are safe. A marketing manager at a company needs to analyze a customer with a given profile, who will buy a new computer. In both of the above examples, a model or classifier is constructed to predict the categorical labels. These labels are risky or safe for loan application data and yes or no for marketing data.

 - У Стратмора стол ломится от заказов. Вряд ли он позволил бы ТРАНСТЕКСТУ простаивать целый уик-энд. - Хорошо, хорошо.  - Мидж вздохнула.  - Я ошиблась.

Data Mining for Student Performance Prediction in Education

 Танкадо отдал кольцо? - скептически отозвалась Сьюзан. - Да. Такое впечатление, что он его буквально всучил - канадцу показалось, будто бы он просил, чтобы кольцо взяли. Похоже, этот канадец рассмотрел его довольно внимательно.  - Стратмор остановился и повернулся к Сьюзан.

Северная Дакота - призрак, сказала она. Сплошная мистификация. Блестящий замысел. Выходит, Стратмор был зрителем теннисного матча, следящим за мячом лишь на одной половине корта. Поскольку мяч возвращался, он решил, что с другой стороны находится второй игрок. Но Танкадо бил мячом об стенку.

Внезапно откуда-то появился пожилой человек, подбежал к Танкадо и опустился возле него на колени. Халохот замедлил шаги. Мгновение спустя появились еще двое - тучный мужчина и рыжеволосая женщина. Они также подошли к Танкадо. - Неудачный выбор места, - прокомментировал Смит.  - Халохот думал, что поблизости никого. Халохот какое-то время наблюдал за происходящим, потом скрылся за деревьями, по-видимому, выжидая.
