7 Data Mining Standard Process (CRISP–DM)
Object-Oriented Programming 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

8 CRISP-DM Object-Oriented Programming

9 1. Business Understanding Phase
Object-Oriented Programming 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

10 2. Data Understanding Phase
Object-Oriented Programming 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

11 3. Data Preparation Phase
Object-Oriented Programming 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

12 4. Modeling phase Select and apply appropriate modeling techniques
Object-Oriented Programming 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

13 Object-Oriented Programming 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

14 Object-Oriented Programming 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

15 Object-Oriented Programming 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
