What is Data Mining ?
• the computational process of discovering patterns in large
data sets involving methods at the intersection of artificial
intelligence, machine learning, statistics, and database
systems.
• The overall goal of the data mining process is to extract
information from a data set and transform it into an
understandable structure for further use.

Data Mining Process
• Cross-Industry Standard Process for Data Mining (CRISP-DM)
consists of six cyclic phases :
• Business Understanding
• Data Understanding
• Data Preparation
• Modeling
• Evaluation
• Deployment

Clustering
• Clustering
• grouping a set of objects in such a way that objects in the same

another) to each other than to those in other groups (clusters)
• Widely used in areas of fraud detection
