Harnessing Large-Scale University Registrar Data for Predictive Insights: A Data-Driven Approach to Forecasting Undergraduate Student Success with Convolutional Autoencoders
This study leverages over a decade of historical data from Louisiana State University (LSU) to forecast graduation outcomes using advanced machine learning techniques, with a focus on convolutional autoencoders (CAEs). We detail the data processing and transformation steps, including feature selection and imputation, to construct a robust dataset. The CAE effectively extracts meaningful latent features, validated through low-dimensional t-SNE visualizations that reveal clear clusters based on class labels, differentiating students likely to graduate from those at risk. A two-year gap strategy is introduced to ensure rigorous evaluation and simulate real-world conditions by predicting outcomes on unseen future data.

Robust Data Preprocessing for Accuracy
Our methodology involved careful handling of a large dataset (94,931 records, 276 features from 2011-2023) to ensure high-quality inputs for predictive modeling. Critical steps included context-based imputation for missing values, transforming categorical and geographic data, and filtering irrelevant cohorts, culminating in a refined dataset of 55,215 student records. This ensures that every piece of data contributes meaningfully to the model's accuracy and generalizability.

Advanced Feature Extraction with CAE
The Convolutional Autoencoder (CAE) played a crucial role in transforming high-dimensional student data into compact, meaningful latent representations. This process not only reduces computational complexity but also preserves critical information, making models more efficient and scalable for large university datasets. The CAE effectively distilled 197 features into a 141-dimensional embedding, retaining over 70% of the original information.

Dimensionality Reduction Achieved by CAE
Testing across various embedding sizes confirmed robust reconstruction performance, with minimal loss in information even at significant compression levels. This demonstrates the CAE's capability to generalize well and avoid overfitting, producing stable and interpretable representations for predictive modeling.

Superior Predictive Performance & Generalization
Our models, particularly Random Forest (RF), demonstrated strong performance in forecasting student graduation outcomes. When benchmarked against traditional methods like Logistic Regression (LR) and Linear Discriminant Analysis (LDA), RF maintained a balanced profile across key metrics, offering high recall without compromising precision. This robust performance is critical for identifying at-risk students effectively and enabling timely interventions.
| Model | Accuracy | F1-score | Precision | Recall | AUC-ROC |
|---|---|---|---|---|---|
| LR | 0.85 | 0.88 | 0.88 | 0.88 | 0.91 |
| LDA | 0.85 | 0.90 | 0.85 | 0.95 | 0.90 |
| RF | 0.85 | 0.89 | 0.85 | 0.94 | 0.90 |
Furthermore, evaluating model generalizability through a two-year temporal gap strategy highlighted the importance of adaptive modeling. While the kNN model showed an average accuracy of 79% under these challenging conditions, it underscored the need for continuous model refinement to adapt to evolving student demographics and institutional policies. Embeddings from the CAE, while slightly reducing raw performance, offer significant computational efficiencies.

Strategic Business Impact for Higher Education
This predictive modeling framework offers profound practical value for both academic advising and institutional planning. By providing early identification of students at risk of not graduating, it enables timely and targeted interventions such as academic support, financial counseling, and mental health services. At the institutional level, aggregated predictions inform strategic decisions on resource allocation, curriculum planning, and long-term forecasting.
Scalable Predictive Analytics for Student Success
The CAE-derived embeddings offer significant advantages for enterprise deployment in higher education. By compressing high-dimensional student data into compact, informative representations, this framework drastically reduces computational overhead and memory requirements, enabling real-time analysis across vast student populations. This efficiency facilitates the deployment of predictive models on existing infrastructure, democratizing advanced analytics for institutions of all sizes. Early identification of at-risk students allows for targeted interventions in academic advising and financial aid, while aggregate predictions inform strategic decisions on curriculum planning and resource allocation. This scalable approach directly translates into improved student retention, enhanced graduation rates, and optimized institutional effectiveness.
