How data mining works

Data preprocessing is the first step in data mining, encompassing data cleaning, integration, transformation, and standardization. Its purpose is to ensure data accuracy and consistency, laying the foundation for subsequent mining work. After preprocessing, features useful for the mining task need to be selected from the data. Features can be data attributes, dimensions, or categories; they reflect the inherent structure and relationships within the data. Appropriate algorithms and tools are then used to analyze the extracted features, identifying hidden patterns and associations. This can be achieved using...Machine Learning,Deep learningThe technology is then implemented. Finally, the mining results need to be evaluated and interpreted. This includes understanding the model's predictive power, identifying the best predictor variables, and interpreting the practical significance of the results.

Data mining utilizes statistics,Machine LearningThis process utilizes multidisciplinary knowledge, including database technology, to extract valuable information from large-scale datasets. It involves the application of algorithms, including a deep understanding of the data and in-depth analysis of the results, ensuring that the extracted information has practical application value for decision support, trend prediction, and anomaly detection.
