Data mining Techniques : Data Genralization, Analytical Chracterization
Data mining is the process of discovering meaningful patterns and insights from large datasets. Two commonly used techniques in data mining are data generalization and analytical characterization.
Data Generalization: Data generalization is the process of summarizing data by replacing low-level data with higher-level data. For example, replacing individual age values with age ranges (such as 0-10, 11-20, etc.) or replacing individual zip codes with region or state names. Data generalization is useful for reducing the amount of data to be analyzed and for protecting individual privacy.
Analytical Characterization: Analytical characterization is the process of using statistical and visualization techniques to gain a deeper understanding of the data. This technique involves identifying patterns, trends, and relationships within the data. Some common analytical techniques used in data mining are clustering, association rule mining, and classification. Analytical characterization can help in making predictions, identifying anomalies, and making decisions based on data insights.
Both data generalization and analytical characterization are important techniques in data mining that help in understanding large datasets and making informed decisions based on data insights.
