— In this digital world, increasing number of organizations are facing the problem of explosion of data and the size of the databases used in today's enterprises has been growing at exponential rates. Data is generated through many sources like business processes, transactions, social networking ...
Data mining is the process of discovering actionable information from large sets of data. Data mining uses mathematical analysis to derive patterns and trends that exist in data. Typically, these patterns cannot be discovered by traditional data exploration because the relationships are too complex or ...
Publisher's description: The fundamental algorithms in data mining and analysis form the basis for the emerging field of data science, which includes automated methods to analyze patterns and models for all kinds of data, with applications ranging from scientific discovery to business intelligence and...
The model is also affected by the data that you train it on: even models trained on the same mining structure can yield different results if you filter the data differently or use different seeds during analysis. However, the actual data is not stored in the model-only summary statistics are...
For example, the statement SELECT * FROM <structure>.CASES returns all the data in the mining structure. To retrieve this information, the mining structure must have been processed, and the results of processing must be cached. The statement SELECT * FROM <model>.CASES returns the same ...
For large volumes of data, searching on meta-data only will not be adequate. Scientists often need to search for data based on actual data values. This is a particular kind of data mining, which searches for data sets based on data content.In this chapter, we first describe the system ...

Analgorithmin data mining (or machine learning) is a set of heuristics and calculations that creates a model from data. To create a model, the algorithm first analyzes the data you provide, looking for specific types of patterns or trends. The algorithm uses the results of this analysis over...
By the study on data mining technologies, we try to find some methods adapting to regional economics. It is found through k-means and CADD algorithms that: high-dimension data is relatively sparse in space distribution and the distance is almost equal. So the algorithm based on distance and ...
The following table lists the different types of nodes that are output in data mining models. Because each algorithm processes information differently, each model generates only a few specific kinds of nodes. If you change the algorithm, the type of nodes may change. Also, if you re...
