CadCNN 1.0: A HYBRID DEEP NETWORK MODEL FOR CARDIAC ARRHYTHMIA DETECTION Bipasha Patnaik, Santanu Sahoo, Debasish Swapnesh Kumar Nayak, Asit Kumar Subudhi Biomedical Engineering Applications Basis and Communications, 2026 Cardiac Arrhythmia, which encompasses irregular heart rhythms such as tachycardia, bradycardia, ectopic pulses, represents a significant cause of cardiovascular morbidity and mortality worldwide, caused by disruptions in the heart’s electrical conduction system. Accurate and automated interpretation of the Electrocardiogram (ECG) is consequently crucial for the timely diagnosis and selection of treatment. This study introduces CadCNN 1.0, a novel hybrid Deep Learning (DL) framework that combines one-dimensional Convolutional Neural Networks (1D-CNN) for spatial feature extraction with Bidirectional Long Short-Term Memory (BiLSTM) for temporal sequence modeling. This methodology enables the accurate characterization of ECG waveforms and the model was trained and validated using the MIT-BIH Arrhythmia Database, classifying ECG signals into five categories: Normal (N), Fusion (F), Supraventricular Ectopic Beat (SVEB), Ventricular Ectopic Beat (VEB), and Unknown (Q) Beat. The Gray Wolf Optimization (GWO) algorithm was employed to optimize feature selection and model convergence, resulting in exceptional diagnostic performance with an Accuracy of 99.92%, Sensitivity (Recall) of 99.81%, Specificity of 99.93%, Precision of 99.92%, [Formula: see text]1-score of 99.92% along with MCC of 99.84% with Number of Wolves (Nw) of 10 represents the number of wolves in the population, corresponding to the number of candidate feature subsets simultaneously explored in each iteration, that enhances population diversity and prevents premature convergence and Max Iteration of 10 which denotes the maximum number of optimization cycles during which the wolves update their positions toward the optimal feature subset, ensuring iterative refinement, stability of global optimum. The confusion matrix demonstrates CadCNN 1.0’s discriminative ability to differentiate morphologically equivalent Arrhythmic classes with near-perfect precision, as evidenced by its strong diagonal dominance and minimal off-diagonal misclassifications. Furthermore, the Breast Cancer Dataset performed cross-domain validation, resulting in an Accuracy of 97.50%, Sensitivity (Recall) of 96.49%, Specificity of 97.18%, Precision of 96.49%, [Formula: see text]1-score of 96.49%, MCC of 92.53%. These results underscore the model’s adaptability to heterogeneous biomedical data. CadCNN 1.0 provides a clinically reliable, generalizable, computationally efficient computer-aided diagnostic system that advances automated Arrhythmia detection and enables intelligent, patient-centered healthcare diagnostics by integrating spatial-temporal feature learning, meta-heuristic optimization, and interpretable confusion-matrix validation.
Attention enhanced hybrid deep learning model with 1D-CNN and BiLSTM for automated sleep apnea detection Bipasha Patnaik, Debasish Swapnesh Kumar Nayak, Santanu Sahoo Discover Applied Sciences, 2025 Sleep Apnea (SA) is an alarming sleep disorder characterized by repeated cessation of breathing during sleep, which frequently results in severe cardiovascular and metabolic impairment. The traditional techniques, such as polysomnography, are time-consuming, costly, and require clinical supervision. To address these challenges, this study proposes a hybrid DL-based framework for automated SA identification with single-lead ECG signals from the PhysioNet Apnea-ECG dataset. The methodology integrates comprehensive signal processing along with feature engineering to improve the morphological, temporal characteristics of ECG signals. The traditional ML models like SVM with Linear, Polynomial, Sigmoid, Radial Basis Kernels, and DL architectures such as 1D-CNN, 1D-CNNN-BiLSTM, and a hybrid 1D-CNN + BiLSTM-Attention mechanism automatically weight temporal features to focus on diagnostically significant ECG segments and improve the hidden feature space representation of prominent patterns. The efficacy of the model is demonstrated in the form of a validated quantitative performance evaluation using 10-fold cross-validation. The model achieved 98.39% Accuracy, 99.02% Precision, 98.29% Sensitivity, 96.53% Specificity, 98.66% F1-Score, 96.67% MCC, 97.78% AUC on PhysioNet-Apnea ECG dataset, indicating strong classification performance with robust generalization across patient’s sub-groups. The strength of the proposed model has been demonstrated using the MIT-BIH Polysomnographic database across various sleep patterns and recording conditions in diagnostic accuracy, efficiency, and generalization across physiological variations. The results have been compared with some of the state-of-the-art methods for establishing the superiority of the proposed model.
Vi-GeN 1.0: GAN-Augmented Vision Transformer Pipeline for Diversified Pneumonia Classification Archana Dash, Soumyarashmi Panigrahi, Debasish Swapnesh Kumar Nayak, Amiya Prasad Dash, Tripti Swarnkar Journal of Transformative Technologies and Sustainable Development, 2025 Pneumonia continues to be one of the global causes of morbidity and mortality, necessitating early and proper diagnosis using chest X-rays (CXRs). Deep learning networks, specifically convolutional neural networks (CNNs), have shown excellent results in identifying pneumonia. But their performance is normally hampered by dataset imbalance, feature redundancy, and local receptive fields, reducing generalizability. To overcome such challenges, the study introduces Vi-GeN 1.0, a GAN-augmented Vision Transformer (ViT) pipeline specifically architected for pneumonia classification robustness. Our method uses Wasserstein GAN with Gradient Penalty (WGAN-GP) to synthesize high-quality CXRs, improving dataset diversity and feature learning. The ViT classifier, trained on the real and synthetic data, learns global contextual representations, resulting in better classification performance. Vi-GeN 1.0 model was tested on the Kaggle Chest X-ray Pneumonia dataset, showing 97.3% accuracy, 98.1% sensitivity, 96.5% specificity, and AUC-ROC of 0.985, performing much better than the baseline ViT model (p < 0.01). The realism and feature preservation of the synthetic images are ensured by FID (22.1), SSIM (0.87), and PSNR (28.9 dB) validation. Our results showed that GAN-based augmentation improves pneumonia classification performance effectively, making Vi-GeN 1.0 a valuable candidate for clinical use, especially in low-resource environments. Future research will investigate multi-class classification, domain generalization, and more sophisticated augmentation methods like diffusion models.
Evaluating the Capability of Large Language Model Chatbots for Generating Plain Language Summaries in Radiology Pradosh Kumar Sarangi, Pratisruti Hui, Himel Mondal, Debasish Swapnesh Kumar Nayak, M. Sarthak Swarup, et al. Iradiology, 2025 Background Plain language summary (PLS) are essential for making scientific research accessible to a broader audience. With the increasing capabilities of large language models (LLMs), there is the potential to automate the generation of PLS from complex scientific abstracts. This study assessed the performance of six LLM chatbots: ChatGPT, Claude, Copilot, Gemini, Meta AI, and Perplexity, in generating PLS from radiology research abstracts. Methods A total of 100 radiology abstracts were collected from PubMed. Six LLM chatbots were tasked with generating PLS for each abstract. Two expert radiologists independently evaluated the generated summaries for accuracy and readability, with their average scores being used for comparisons. Additionally, the Flesch–Kincaid (FK) grade level and Flesch reading ease score were applied to objectively assess readability. Results Comparisons of LLM‐generated PLS revealed variations in both accuracy and readability across the models. Accuracy was highest for ChatGPT (4.94 ± 0.18) followed by Claude (4.75 ± 0.31). Readability was highest for ChatGPT (4.83 ± 0.27) followed by Perplexity (4.82 ± 0.29). The Flesch reading ease score was highest for Claude (62.53 ± 10.98) and lowest for ChatGPT (40.10 ± 11.24). Conclusion LLM chatbots show promise in the generation of PLS, but performance varies significantly between models in terms of both accuracy and readability. This study highlights the potential of LLMs to aid in science communication but underscores the need for careful model selection and human oversight.
