Standard Proses Penelitian pada Data Mining
Data Mining Standard Process (CRISP–DM)
A cross-industry standard was clearly required that is industry neutral, tool-neutral, and application-neutral
The Cross-Industry Standard Process for Data Mining (CRISP–DM) was developed in 1996 (Chapman, 2000)
CRISP-DM provides a nonproprietary and freely available standard process for fitting data mining into the general problem-solving strategy of a business or research unit
CRISP-DM
1. Business Understanding Phase Enunciate the project objectives and requirements
clearly in terms of the business or research unit as a whole
Translate these goals and restrictions into the formulation of a data mining problem definition
Prepare a preliminary strategy for achieving these objectives
2. Data Understanding Phase Collect the data Use exploratory data analysis to familiarize yourself
with the data and discover initial insights Evaluate the quality of the data If desired, select interesting subsets that may
contain actionable patterns
3. Data Preparation Phase Prepare from the initial raw data the final data set
that is to be used for all subsequent phases. This phase is very labor intensive
Select the cases and variables you want to analyze and that are appropriate for your analysis
Perform transformations on certain variables, if needed
Clean the raw data so that it is ready for the modeling tools
4. Modeling phase Select and apply appropriate modeling techniques Calibrate model settings to optimize results Remember that often, several different techniques
may be used for the same data mining problem If necessary, loop back to the data preparation
phase to bring the form of the data into line with the specific requirements of a particular data mining technique
5. Evaluation phase Evaluate the one or more models delivered in the
modeling phase for quality and effectiveness before deploying them for use in the field
Determine whether the model in fact achieves the objectives set for it in the first phase
Establish whether some important facet of the business or research problem has not been accounted for sufficiently
Come to a decision regarding use of the data mining results
6. Deployment phase Make use of the models created: Model creation
does not signify the completion of a project Example of a simple deployment: Generate a report Example of a more complex deployment:
Implement a parallel data mining process in another department
For businesses, the customer often carries out the deployment based on your model
