    Diabetes mellitus is a chronic metabolic disorder that requires accurate and timely prediction for early diagnosis and intervention. Traditional machine learning methods often struggle to capture nonlinear interactions and temporal dependencies in clinical datasets. To address this, we propose a hybrid framework that integrates Dynamic Mode Decomposition (DMD) for feature augmentation with a bi-layer Long Short-Term Memory (LSTM) network for robust classification. DMD extracts latent dynamic patterns from static clinical attributes, transforming them into pseudo-sequential representations that the LSTM models use to capture long-term dependencies. The framework incorporates SMOTE-based class balancing and grid-optimized hyperparameters to improve robustness and generalization. Evaluation on the PIMA Indian Diabetes dataset shows that the proposed LSTM+DMD model outperforms standalone architectures, achieving 98.92% accuracy, 99.33% precision, 97.37% recall, and an F1-score of 98.34%. Ablation studies confirm the complementary roles of DMD and LSTM, while comparisons with state-of-the-art methods highlight the model’s novelty and effectiveness. These results demonstrate that the proposed framework provides a highly accurate and interpretable solution for diabetes prediction, with promising applicability in clinical decision support systems.

  • Comparative Analysis of LSB, Phase Coding, and Spread Spectrum Techniques for Audio Steganography

    In the digital era, ensuring the secure transmission of confidential information is critically important. Audio steganography has emerged as an effective approach for concealing data within audio signals while preserving perceptual quality. This paper presents a comprehensive comparative study of three audio steganographic techniques: Least Significant Bit (LSB) modification, Phase Coding, and Spread Spectrum. Each method was experimentally implemented to embed text files of varying sizes (20 KB, 40 KB, 60 KB, and 80 KB) into digital audio signals using three different music files (rock, hip-hop, and EDM). Experimental evaluations were conducted to measure objective metrics such as Peak Signal-to-Noise Ratio (PSNR), Signal-to-Noise Ratio (SNR), and Bit Error Rate (BER). Results demonstrate that the LSB method, tested at different bit planes (5<sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">th</sup>, 6<sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">th</sup>, and 7<sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">th</sup> bits), achieves high embedding capacity and near-perfect extraction accuracy but is more vulnerable to signal processing distortions. Phase coding achieves a balance between perceptual transparency and capacity but shows moderate robustness under distortion. Spread spectrum, although offering lower embedding capacity, exhibits the highest robustness and signal fidelity, with superior PSNR and SNR values and acceptable error rates under noisy conditions. This comparative analysis provides practical insights into the trade-offs among capacity, imperceptibility, and robustness, guiding the selection of suitable audio steganography methods for diverse security and multimedia applications.
  • Performance Comparison of Machine Learning Techniques for Recognizing Disguised Faces

    Disguised face recognition poses significant challenges due to identity-obscuring factors such as masks, spectacles, cosmetics, and other occlusions. This study explores the effectiveness of machine learning approaches in addressing these challenges by evaluating multiple classifiers and systematically optimizing their performance through grid search. Individual models—including Random Forest (RF), Support Vector Machine (SVM), Decision Tree (DT), and K-Nearest Neighbors (KNN)—were trained and assessed using metrics such as AUC-ROC, F1-score, accuracy, precision, and recall, with XGBoost serving as a benchmark. To enhance recognition accuracy, ensemble learning strategies were employed, examining all possible combinations of two-, three-, and four-model ensembles using both majority voting and weighted average techniques. The ensemble models consistently outperformed individual classifiers, with the KNN+RF+SVM ensemble achieving the highest accuracy and robustness. These results underscore the importance of feature fusion and model integration in improving disguised face recognition. By mitigating the effects of facial concealments, this work contributes to the development of more secure and reliable biometric authentication systems.
