1. Feature Engineering: Create new informative features or use domain knowledge.
2. Feature Selection: Remove irrelevant or redundant features to reduce noise.
3. Hyperparameter Tuning: Systematically optimize model parameters (e.g., via grid/random search).
4. Advanced Techniques: Use ensemble methods (bagging, boosting, stacking) or more sophisticated algorithms.
5. Cross-Validation & Resampling: Employ k-fold cross-validation for robust evaluation and techniques like SMOTE for class imbalance.
6. Preprocessing: Ensure proper normalization, handling of missing values, and outlier treatment.
