Using cross-validation to evaluate classifier performance in KNIME.
// Workflow steps:
// 1. File Reader -> load dataset
// 2. Cross Validation Loop Start
// 3. Decision Tree Learner -> train model inside loop
// 4. Predictor -> predict inside loop
// 5. Scorer -> evaluate inside loop
// 6. Cross Validation Loop End -> collect resultsKnime Language Guide
