| description | Abstract Accurate prediction of student performance is essential for the creation of adaptive learning frameworks and the best utilization of educational strategies. In this work, we apply ensemble learning and neural networks to investigate data from multiple sources about students, two real educational datasets from Kaggle, and two synthetically generated datasets. A Python-based generative script was used to create one synthetic dataset; another synthetic dataset is created by augmenting a smaller Kaggle dataset while keeping its original statistical distribution. The Integrated Synthetic Data will make the model more robust, mitigate class imbalance, and generalize predictively in a much better way across heterogeneous educational data. In this paper, we implement several ensemble models-AdaBoost, Gradient Boosting, XGBoost, LightGBM, and CatBoost-and deep learning architectures such as Deep Neural Networks (DNN), Convolutional Neural Networks (CNN), Long Short-Term Memory (LSTM), and Recurrent Neural Networks (RNN). These models are evaluated using accuracy, precision, recall, F1-score, and ROC-AUC to assess their predictive effectiveness. Experimental results demonstrate that CatBoost outperforms other ensemble models with an accuracy of 0.7143 and an F1-score of 0.7338, while CNN achieves the highest performance for sequential data (accuracy: 0.6786). ROC-AUC analysis confirms CatBoost and XGBoost as top-performing classifiers, while CNN and DNN exhibit superior capability in handling temporal patterns. The study highlights the impact of dataset augmentation and synthetic data generation on improving predictive accuracy in educational data mining, reinforcing the importance of data-centric approaches for building intelligent, and evidence-driven educational systems.
