Chapter 9, Problem 8DQ
Explanation of Solution
CRISP-DM:
CRISP-DM is cross-industry process for data mining. It provides structured approach for planning the data mining project. It consists of six phase structure approach for planning and executing the data mining project. The six phases of CRISP-DM model are as follows:
- Business understanding
- Data understanding
- Data preparation
- Modeling
- Evaluation
- Deployment
Planning and executing the data mining effort:
Business understanding:
In this phase, first the business goals are planned and clarified for the data mining project. The planned goals are then converted into the predictive analysis problem. After the conversion process, the project plan is designed to accomplish the objectives.
Data understanding:
In this phase, the data is gathered from multiple sources...
