While data mining and machine learning are closely related, they serve different purposes within the broader field of data analysis. Data mining is primarily concerned with discovering patterns and extracting knowledge from large datasets. On the other hand, machine learning focuses on developing algorithms that can learn from data and make predictions or decisions. Both fields complement each other in the data analysis process, with data mining providing the foundation for machine learning to operate effectively.
Data mining techniques
Data mining encompasses a wide range of techniques and algorithms used to extract valuable insights from data. Below are three commonly used data mining techniques:
1. Clustering
Clustering is a technique used to group similar data instances together based on their similarity or distance. It helps in identifying natural groupings within the data and understanding the underlying structure. Clustering is commonly used for customer segmentation, image recognition, and anomaly detection.
2. Association rule mining
Association rule mining is used to discover relationships and correlations between items in a dataset. It helps in finding interesting patterns and associations that can be utilized for decision making. Association rule mining is frequently applied in market basket analysis and recommendation systems.
3. Anomaly detection
Anomaly detection is a technique used to identify abnormal patterns or outliers in a dataset. It helps in detecting unusual behavior or instances that deviate significantly from the norm. Anomaly detection is valuable in fraud detection, network intrusion detection, and predictive maintenance.
