Data Preprocessing for Data Mining addresses one of the most important issues within the well-known Knowledge Discovery from Data process. Data directly taken from the source will likely have inconsistencies, errors or most importantly, it is not ready to be considered for a data mining process. Furthermore, the increasing amount of data in recent science, industry and business applications, calls to the requirement of more complex tools to analyze it.

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.

PREPROCESSING IN DATA MINING

Documentation Help Center. Data can require preprocessing techniques to ensure accurate, efficient, or meaningful analysis. Data cleaning refers to methods for finding, removing, and replacing bad or missing data. Detecting local extrema and abrupt changes can help to identify significant data trends. Smoothing and detrending are processes for removing noise and polynomial trends from data, while scaling changes the bounds of the data.

Luengo , F. Herrera , Tutorial on practical tips of the most influential data preprocessing algorithms in data mining. Data preprocessing is a major and essential stage whose main goal is to obtain final data sets that can be considered correct and useful for further data mining algorithms. This paper summarizes the most influential data preprocessing algorithms according to their usage, popularity and extensions proposed in the specialized literature. For each algorithm, we provide a description, a discussion on its impact, and a review of current and further research on it.

 Вы набрали правильно, - сказал он осторожно, - но это служба сопровождения. Звонивший некоторое время молчал. - О… понимаю. Прошу прощения.

 - Но у меня такое впечатление, что мы совершенно случайно обнаружили и нейтрализовали Северную Дакоту.  - Он покачал головой, словно не веря такую удачу.  - Чертовское везение, если говорить честно.

 Идемте, мисс Флетчер, - сказал Фонтейн и прошел.  - Нам сейчас пригодится любая помощь. Посверкивая в красноватом свете туннельных ламп, перед ними возникла стальная дверь. Фонтейн набрал код на специальной углубленной панели, после чего прикоснулся к небольшой стеклянной пластинке. Сигнальная лампочка вспыхнула, и массивная стена с грохотом отъехала влево.
