Descriptive Data Mining vs. Predictive Data Mining: What's the Difference?
Edited by Aimie Carlson || By Janet White || Published on February 25, 2024
Descriptive data mining uncovers patterns to understand past behavior; predictive data mining uses that information to forecast future outcomes.
Key Differences
Descriptive Data Mining focuses on understanding past behaviors by finding patterns and relationships in historical data. It helps in summarizing the data into meaningful information. In contrast, predictive data mining uses the patterns identified by descriptive analysis to model and forecast potential future events. It is more about making predictions based on known properties.
Descriptive Data Mining provides insights into what has happened. For example, it might analyze customer purchase history to understand buying trends. Predictive Data Mining technique uses these insights to anticipate future trends or behaviors. For instance, it might predict future purchase behaviors of customers based on their history.
Descriptive Data Mining often involves data summarization, clustering, and association. It helps businesses understand their current situation. Predictive Data Mining employs algorithms like regression and classification to predict future scenarios. It is more about applying models to forecast future outcomes.
Descriptive Data Mining is crucial for businesses to make sense of large volumes of data and draw meaningful conclusions. Predictive Data Mining takes these conclusions a step further by applying them to predict future trends and behaviors, thereby aiding in strategic planning.
Descriptive Data Mining is about the interpretation of historical data to better understand changes that have occurred in a business. Predictive Data Mining aims to use this historical data to predict future occurrences, helping in decision making and planning.
