What is Data Mining? Data Mining is a process of extracting implicit knowledge from large amounts of data. It uses methods such as statistics, machine learning, and artificial intelligence to discover rules, trends, associations, and patterns from massive amounts of data to support decision making. Figuratively speaking, data mining is like a treasure hunter looking for valuable "gold" in a vast ocean of data. What can data mining do? Predictive analysis: Predict future trends, such as sales, customer churn, etc.
  
Classification: Classify data into different categories Email List such as spam classification and customer grouping. Clustering: Discover similar groups in data, such as market segmentation. Association rule mining: Discover associations between things, such as shopping basket analysis. Anomaly detection: Discover outliers in data, such as fraud detection. The process of data mining Data collection: Collect data from various sources, such as databases, sensors, web pages, etc.





Data preprocessing: Clean, transform, and integrate data to remove noise and missing values. Data mining: Select appropriate algorithms to mine data and discover patterns. Pattern evaluation: Evaluate mining results and verify their effectiveness. Knowledge representation: Present mining results in a visual or textual form for easy understanding. Application scenarios of data mining Business: Customer relationship management, marketing, risk control, etc. Financial: Fraud detection, credit assessment, investment analysis, etc. Medical: Disease diagnosis, drug development, medical image analysis, etc. Scientific research: Bioinformatics, astronomy, social sciences, etc.
