Data Preprocessing Example — Rapidminer Code
A workflow showing basic data preprocessing using operators in RapidMiner Studio.
// Workflow steps:
// 1. Import dataset
// 2. Use 'Replace Missing Values' operator
// 3. Normalize numerical attributes using 'Normalize'
// 4. Filter examples or attributes if needed
// 5. Output processed data to 'Write CSV' operatorRapidminer Language Guide
