Ensemble Learning Example — Knime Code

Using ensemble methods like Random Forest or Gradient Boosting in KNIME.

// Workflow steps:
// 1. File Reader -> load dataset
// 2. Partitioning -> split data
// 3. Random Forest Learner -> train model
// 4. Predictor -> predict on test
// 5. Scorer -> evaluate performance
// 6. Optionally, combine multiple learners using Ensemble nodes
