6. Standard Proses Penelitian pada Data Mining

7. Data Mining Standard Process(CRISP–DM) • A cross-industry standard was clearly required that is industryneutral,tool-neutral, and application-neutral • The Cross-Industry Standard Processfor Data Mining (CRISP–DM) was developed in 1996 (Chapman, 2000) • CRISP-DM provides a nonproprietary and freely availablestandard process for fitting data mining into the general problem-solving strategyof a business or research unit

8. CRISP-DM

9. 1. Business UnderstandingPhase • Enunciate the project objectives and requirements clearly in terms of thebusiness 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

10. 2. Data UnderstandingPhase • Collectthedata • Use exploratory data analysis to familiarize yourself with the data and discoverinitialinsights • Evaluatethe quality of the data • If desired, select interesting subsets that may contain actionable patterns

11. 3. Data PreparationPhase • Prepare from the initial raw data the final data set that is to be used for allsubsequent phases. This phase is very labor intensive • Select the cases and variables you want to analyze and that are appropriate for youranalysis • Perform transformations on certain variables, if needed • Clean the raw data so that it is ready for the modeling tools

12. 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 miningproblem • If necessary, loop back to the data preparation phase to bring the form ofthe data into line with the specific requirements of a particular data miningtechnique

13. 5. Evaluationphase • Evaluate the one or more models delivered in the modeling phase for qualityand effectiveness before deploying them for use in the field • Determine whether the model in fact achieves the objectives set for it in thefirstphase • Establish whether some important facet of the business or research problemhas not been accounted for sufficiently • Come to a decision regarding use of the data mining results

14. 6. Deploymentphase • 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 miningprocessinanotherdepartment • For businesses, the customer often carries out the deployment based on your model

15. Latihan • Pelajari dan pahami Case Study 1-5 dari buku Larose (2005) Chapter 1 • Pelajari dan pahami bagaimana menerapkan CRISP-DM pada tesis Firmansyah (2011) tentang penerapan algoritma C4.5 untuk penentuan kelayakan kredit
