PCE-FL: A Personalized, Clustered, and Communication-Efficient Federated Learning Framework for Robust Tomato Leaf Disease Detection Pradeep Gupta, Sonam Gupta, Lipika Goel, Abhay Kumar Agarwal, Arjun Singh, Vijay Shankar Sharma, Chiranji Lal Chowdhary, Ruchita Chowdhary Agriengineering, 2026 Tomato leaf diseases represent a persistent threat to global food security, causing annual crop losses of 20% to 40%. Although deep learning models achieve accuracies exceeding 95% in centralized settings, their deployment across distributed farms is constrained by data privacy concerns, communication bottlenecks, and heterogeneous data quality. This paper proposes Personalized, Clustered, and Communication-Efficient Federated Learning (PCE-FL), a framework that integrates three synergistic components: (1) server-side client clustering to group farms with similar data distributions for personalized model training; (2) federated knowledge distillation to reduce communication overhead by over 91%; and (3) reputation-based aggregation to ensure robustness against unreliable contributions. Extensive experiments on realistic non-IID simulations of the PlantVillage tomato dataset Dirichlet(α∈{1.0,0.5,0.1}) demonstrate that PCE-FL achieves 89.1% accuracy under extreme heterogeneity (α=0.1), surpassing FedAvg by 10.9 and IFCA by 4.8 percentage points, while maintaining a 91% reduction in communication cost. All improvements are statistically significant (p<0.001). These results advance the practical deployment of privacy-preserving collaborative AI in resource-constrained agricultural environments.
Integrating feature fusion with hybrid optimization for multiple sclerosis MRI classification Nandini Anam, Sharief Basha S, Chiranji Lal Chowdhary Array, 2026 Detecting Multiple Sclerosis (MS) has previously been difficult to identify with MRI scans due to the subtlety and dispersion of lesions, as well as other imaging anomalies. The researchers in this study created a unique hybrid framework that combines two state-of-the-art convolutional neural networks, ResNet-50 and EfficientNet-B7. Additionally, a new hybrid bio-inspired optimisation strategy combining the Grey Wolf Optimiser (GWO) and the Genetic Algorithm (GA) is described. The technique simplifies the computations and ensures that the best characteristics are picked. We extracted deep features from both CNNs, used Principal Component Analysis (PCA) to reduce them to high dimensions, and then employed the GA-GWO method to identify suitable features. The enhanced artificial neural network (ANN) classifier outperformed standalone CNN-based models, achieving a maximum accuracy of 90.67%(refer to table 4). The suggested framework for dependable and comprehensible precision and processing efficacy. This work has the potential to motivate future studies in related areas.
Hybrid deep learning and feature optimization approach for early detection of multiple sclerosis Nandini Anam, Sharief Basha S., Chiranji Lal Chowdhary Frontiers in Human Neuroscience, 2026 The healthcare field increasingly relies on autonomous systems for the detection and analysis of Multiple Sclerosis (MS) to minimize diagnostic delays, resource burdens, reduce the progression of disability, and enhance clinical decision-making efficiency. Such systems ensure accurate and timely treatment, ultimately improved patient outcomes. In this study, a hybrid framework combining deep learning-based feature extraction, metaheuristic feature selection, and machine learning (ML) classifiers is proposed for accurate MS classification. All MRI images were preprocessed using Contrast Limited Adaptive Histogram Equalization (CLAHE), resizing, and normalization to enhance contrast and standardize the input dimensions. Deep features were extracted using the pretrained VGG16 convolutional neural network (CNN), in which the fully connected layers were removed, and the convolutional base was used to obtain high-dimensional features per image. To reduce dimensionality and improve classification performance, the Whale Optimization Algorithm (WOA) was employed to select the most discriminative subset of features using a Support Vector Machine (SVM)-based fitness function. Multiple classifiers were then trained and evaluated using the optimized feature set. Among them, the Artificial Neural Network integrated with WOA (ANN+WOA) achieved the highest classification accuracy of 98%, demonstrating the potential of the proposed model for reliable, efficient, and automated MS diagnosis.

Hybrid feature optimized CNN for rice crop disease prediction S. Vijayan, Chiranji Lal Chowdhary Scientific Reports, 2025 The agricultural industry significantly relies on autonomous systems for detecting and analyzing rice diseases to minimize financial and resource losses, reduce yield reductions, improve processing efficiency, and ensure healthy crop production. Advances in deep learning have greatly enhanced disease diagnostic techniques in agriculture. Accurate identification of rice plant diseases is crucial to preventing the severe consequences these diseases can have on crop yield. Current methods often struggle with reliably diagnosing conditions and detecting issues in leaf images. Previously, leaf segmentation posed challenges, and while analyzing complex disease stages can be effective, it is computationally intensive. Therefore, segmentation methods need to be more accurate, cost-effective, and reliable. To address these challenges, we propose a hybrid bio-inspired algorithm, named the Hybrid WOA_APSO algorithm, which merges Adaptive Particle Swarm Optimization (APSO) with the Whale Optimization Algorithm (WOA). For disease classification in rice crops, we utilize a Convolutional Neural Network (CNN). Multiple experiments are conducted to evaluate the performance of the proposed model using benchmark datasets (Plantvillage), with a focus on feature extraction, segmentation, and preprocessing. Optimizing feature selection is a critical factor in enhancing the classification algorithm’s accuracy. We compare the accuracy, sensitivity, and specificity of our model against industry-standard techniques such as Support Vector Machine (SVM), Artificial Neural Network (ANN), and conventional CNN models. The experimental results indicate that the proposed hybrid approach achieves an impressive accuracy of 97.5% (Refer Table 8), which could inspire further research in this field.
Intelligent health model for medical imaging to guide laymen using neural cellular automata Sandeep Kumar Sharma, Chiranji Lal Chowdhary, Vijay Shankar Sharma, Adil Rasool, Arfat Ahmad Khan Scientific Reports, 2025 A layman in health systems is a person who doesn't have any knowledge about health data i.e., X-ray, MRI, CT scan, and health examination reports, etc. The motivation behind the proposed invention is to help laymen to make medical images understandable. The health model is trained using a neural network approach that analyses user health examination data; predicts the type and level of the disease and advises precaution to the user. Cellular Automata (CA) technology has been integrated with the neural networks to segment the medical image. The CA analyzes the medical images pixel by pixel and generates a robust threshold value which helps to efficiently segment the image and identify accurate abnormal spots from the medical image. The proposed method has been trained and experimented using 10000+ medical images which are taken from various open datasets. Various text analysis measures i.e., BLEU, ROUGE, and WER are used in the research to validate the produced report. The BLEU and ROUGE calculate a similarity to decide how the generated text report is closer to the original report. The BLEU and ROUGE scores of the experimented images are approximately 0.62 and 0.90, claims that the produced report is very close to the original report. The WER score 0.14, claims that the generated report contains the most relevant words. The overall summary of the proposed research is that it provides a fruitful medical report with accurate disease and precautions to the laymen.
