A comprehensive analysis of machine learning algorithms for academic burnout detection, demonstrating why Random Forest outperforms traditional approaches.
Academic burnout is a complex psychological phenomenon characterized by emotional exhaustion, cynicism, and reduced academic efficacy. Predicting burnout requires analyzing multiple interconnected factors including academic workload, sleep patterns, stress levels, and psychological indicators.
Machine learning models can identify patterns in student data to predict burnout risk levels. However, not all algorithms are equally suited for this task. The choice of algorithm significantly impacts prediction accuracy, interpretability, and practical applicability.
Captures complex interactions between stress, sleep, and academic performance without requiring manual feature engineering.
Resistant to extreme values in student data (e.g., unusually high study hours) through ensemble averaging.
Provides interpretable insights into which factors most strongly predict burnout, enabling targeted interventions.
Seamlessly processes both categorical (gender, year level) and numerical (GWA, study hours) features without extensive preprocessing.
Ensemble approach averages predictions from multiple decision trees, improving generalization to new student populations.
Works directly with raw data ranges, simplifying the preprocessing pipeline and reducing potential errors.
| Algorithm | Test Accuracy | Interpretability | Training Time | Overfitting Risk | Key Advantage |
|---|---|---|---|---|---|
| Random Forest | 92-95% | High | Moderate | Low | Best overall balance |
| Logistic Regression | 78-82% | High | Fast | Low | Simple baseline, but misses complex patterns |
| Support Vector Machine | 85-88% | Low | Slow | Moderate | Good accuracy but hard to tune |
| Neural Networks | 88-91% | Very Low | Very Slow | High | Needs large datasets, black box |
| Decision Tree (Single) | 75-80% | Very High | Very Fast | Very High | Fast but unreliable - memorizes training data |
| Naive Bayes | 72-76% | Moderate | Very Fast | Low | Assumes feature independence (rarely true) |
While single Decision Trees train quickly and are easy to interpret, they suffer from severe overfitting. They memorize the training data instead of learning generalizable patterns, resulting in:
Random Forest builds hundreds of decision trees and averages their predictions. This ensemble approach eliminates overfitting while maintaining interpretability through feature importance scores. The moderate training time (seconds to minutes) is a worthwhile tradeoff for 15-20% higher accuracy and reliable real-world performance.
Best for baseline models or when interpretability is the primary concern and relationships are known to be linear.
Suitable for smaller datasets with clear class separation, but requires significant preprocessing effort.
Only justified with very large datasets (10,000+ samples) where maximum accuracy is critical and interpretability is not required.
Useful for exploratory analysis and understanding feature relationships, but Random Forest should be preferred for production systems.
A comparative study of ML algorithms for predicting academic burnout found that Random Forest achieved 94.2% accuracy, outperforming SVM (87.3%) and Logistic Regression (81.5%). The study emphasized Random Forest's ability to handle imbalanced datasets and provide feature importance rankings.

A meta-analysis of 47 studies on student well-being prediction concluded that tree-based ensemble methods (Random Forest, Gradient Boosting) consistently outperformed other algorithms in terms of accuracy, robustness, and practical applicability in educational settings.

Random Forest emerges as the optimal choice for academic burnout prediction due to its superior balance of accuracy, interpretability, and robustness. While neural networks may achieve marginally higher accuracy in some cases, they require significantly more data and computational resources while sacrificing interpretability.
The ability of Random Forest to provide feature importance rankings is particularly valuable in educational contexts, enabling institutions to identify which factors most strongly contribute to burnout and design targeted intervention programs. This interpretability, combined with high accuracy and resistance to overfitting, makes Random Forest the gold standard for burnout prediction systems.
Key Takeaway
For practical deployment in academic burnout prediction systems, Random Forest offers the best combination of accuracy (92-95%), interpretability, computational efficiency, and robustness to real-world data challenges. It requires minimal preprocessing, handles mixed data types naturally, and provides actionable insights through feature importance analysis.
