Classification Workflow — Orange Code
A visual workflow for performing classification using Orange widgets.
// In Orange Canvas:
// 1. Load dataset using 'File' widget
// 2. Add 'Select Columns' to choose features and target
// 3. Add 'Random Forest' or 'Logistic Regression' widget
// 4. Connect to 'Test & Score' to evaluate
// 5. Optionally add 'Confusion Matrix' to view resultsOrange Language Guide
