Data Mining with Algebraic condition Motivation Mathematical methods provide a systematic analysis of large amounts of measurement files.

13 Data Mining with Algebraic condition Motivation Mathematical methods provide a systematic analysis of large amounts of measurement files. Different measurement file formats are possible (MDF,DAT,BLF ) A report file provides you with hits to analyze. Methods overview Function (library) > MaxValue>= 100 Matlab/Simulink model > Complex algorithm Algebraic condition > Signal1 >=90 && Signal2==1 Script 13/18

14 Data Mining with Algebraic condition Checklist for the Data Mining Analysis 1. Preparation of the CANape configuration a. Use just one file to visualize the file channels to be analyzed 2. Configuration of the Data Mining analysis a. Definition of the file filter list b. Definition of the method(s) c. Configuration of the options 3. Evaluation of the report file a. Sighting of the hits navigated over the Symbol Explorer or the Data Mining GUI 14/18

15 Data Mining with Algebraic condition Step 2a of the Checklist Definition of the file filter list Whole directories Single files (different formats) 15/18
