Biometric identification from medical images is of increasing interest in forensic-motivated research, particularly in scenarios where conventional soft-tissue-based modalities may become unreliable. This study presents an anatomically motivated feasibility framework that investigates the discriminative potential of skeletal-only cues extracted from chest X-ray radiographs for person identification. Leveraging the relative structural stability of bone anatomye propose a deep metric learning framework utilizing a Triplet Network with a ResNet-based backbone to extract and cluster discriminative skeletal embeddings. The framework is evaluated on the NIH ChestXray14 dataset as a large-scale clinical proxy for anatomical variability, achieving an identification accuracy of 97.3% under the considered experimental protocol. To analyze the learned embedding space, dimensionality reduction techniques including UMAP and t-SNE are employed to visualize identity clustering and inter-subject separability. Furthermore, explainable artificial intelligence (XAI) techniques, specifically Grad-CAM, are applied to provide anatomically grounded interpretations of the regions contributing to identity discrimination. The study is positioned as a proof-of-concept investigation aimed at establishing a methodological and analytical foundation for skeletal-based biometric modeling rather than as a fully validated forensic deployment system. The results highlight the potential of skeletal-only representations for identity discrimination and underline the importance of future validation on dedicated forensic and post-mortem datasets, as well as enhanced segmentation protocols, to further advance explainable and privacy-aware biometric research.
Parkinson's disease (PD), the second most prevalent neurodegenerative disorder globally, afflicting approximately 10 million individuals, necessitates early detection for optimal management. In this paper, we propose deep learning models to discern Parkinson's disease through the nuanced analysis of handwriting with the overall objective of achieving transparency and trustworthiness through the integration of Explainable and Interpretable AI.Leveraging transfer learning from well-established VGG16 and VGG19 architectures and introducing two bespoke CNN models (PD-Detect1 and PD-Detect2), we meticulously scrutinize diverse datasets (HandPD, NewhandPD, Parkinson Drawing) to ascertain the efficacy of our approach. LIME and SHAP Explainable AI techniques are employed to pinpoint specific regions of the spiral drawings that significantly influence the predictions made by the VGG16 and PD-Detect2 models. Additionally, Convolutional Filter Visualization and Grad-CAM are utilized to illustrate how the convolutional layers of the PD-Detect2 model function. Finally, LIME is applied to the PD-Detect2 model to identify visual markers of handwriting symptoms in the spiral drawing.Remarkable results underscore our reliance on VGG16 and VGG19 for precise identification, achieving an outstanding 100% accuracy in the waves drawing dataset. PD-Detect1 exhibits commendable performance with an accuracy of 94.44% in the meander of NewhandPD dataset, while VGG16 achieves an accuracy of 95%. VGG16 records 95% accuracy while PD-Detect2 achieves 85% accuracy in the spiral drawing dataset. Both results further bolstered to 100% with the application of classic data augmentation techniques. The Positive/Negative superpixels from LIME and SHAP highlight the key regions used by VGG16 and PD-Detect2 for predictions, while PD-Detect2 places more emphasis on disease-related features. Visualizing convolutional filters provided insight into the functionality of each layer within the PD-Detect2 model, while the Class Activation Maps produced by Grad-CAM highlighted the image regions most influential to the model's decision. Ultimately, LIME's superpixels identified visual markers of handwriting symptoms associated with Parkinson's disease.Explainable AI and Interpretable AI enhance the quality of CNN models and support the decision-making process, enabling healthcare professionals to more accurately assess disease probability and monitor treatment responses. This leads to a more effective system for the early diagnosis of Parkinson's disease through prediction and visual monitoring of handwriting symptoms.
E-learning was developed in one of the steps of the education world, thus providing personalized and flexible learning environments. Nevertheless, the puzzle is yet to get the students to participate in an Open Classroom (OCR) setting in a way that is actively involved. They mostly work alone with digital platforms as they always did, and teachers cannot manage the task of organizing collaboration in this virtual room. Therefore, we introduce a hybrid Convolutional Neural Networks (CNN)-Vision Transformers (ViT) model to detect real-time engagement. In particular, CNN layers are exploited for local features, while the ViT network uses global attention mechanisms to grab spatial and contextual clues, e.g., facial expressions, and body postures. This method is superior because it integrates two different types of modules, which can take advantage of the pros in a limited field and a coverage context, and we can thus achieve a deeper observation of student action. The model was taught with the Video-based Student Engagement Measurement Dataset and there was a success of 85
With the rapid expansion of e-learning platforms, maintaining academic honesty during online assessments has become increasingly challenging. Traditional monitoring methods often fall short in detecting advanced cheating behaviors and may raise privacy concerns among students. To address these limitations, we propose LSTM-SWAP, a hybrid deep learning model that combines Long Short-Term Memory (LSTM) networks with a specialized attention mechanism called Sliding Window Attention Processor (SWAP) that focuses on key patterns in student behavior over time. This approach allows the model to highlight important behavioral cues while filtering out irrelevant data, thereby improving detection accuracy. Unlike conventional systems that rely on fixed features, LSTM-SWAP adapts dynamically to new and evolving cheating strategies, ensuring resilience against emerging threats. Additionally, the model is designed to reduce false alarms, promoting fairness by minimizing the risk of misidentifying honest students. We evaluated our model on a behavioral dataset based on mouse movement patterns using stratified fivefold cross-validation, achieving an average accuracy of 97.73

This paper proposes a hybrid technique for the classification of MOOCs courses based on the integration of Convolutional Neural Networks (CNN) and the Lion Optimization Algorithm (LOA). It ensures better performance in classification by including the strongest pattern recognition capability of CNN and the powerful hyperparameter optimization by LOA. We also contrasted our approach with various algorithms, including biologically motivated optimization algorithms like the Whale Optimization Algorithm (WOA), Particle Swarm Optimization (PSO), and Ant Colony Optimization (ACO). We also contrast deep learning architectures like Bidirectional Encoder Representations from Transformers (BERT) and Long Short-Term Memory (LSTM) and transformer-based embeddings (sentence embeddings from a pretrained transformer (SimCSE) plus an MLP classifier). We conduct our evaluation on a new dataset that has not been studied in the literature. These experimental results show that the CNN/LOA outperforms the other methods, with testing accuracy at 96.34

Precisely dating historical manuscripts represents a paramount endeavor in the comprehension and the interpretation of their historical significance as well as in the preservation of our cultural heritage; however, despite the strides made in computer-based dating methodologies, the quest for heightened robustness persists. Recent advancements in vision transformers, renowned for their success across diverse image processing domains, have stimulated our inquiry into their potential applicability in the domain of historical manuscript dating. In our pursuit of achieving efficient refinement of the manuscript and ensuring pristine datasets for subsequent analysis, we initiate a meticulous dataset preprocessing step. This involves employing accurate methodologies for denoising through the Non-Local-Means algorithm, and binarization using the Canny-edge detector. Following these preprocessing steps, we delve into the intricate realm of feature detection using the Harris-corner detector. This detector is employed to extract keypoints from the manuscript, and we subsequently apply clustering to these keypoints using the k-means algorithm. Our dual objective here is to extract significant patches of specific dimensions and engage in a systematic augmentation of our dataset. Through this process, we aim to amplify the depth and diversity of our dataset, thereby empowering our models with an enriched corpus of historical knowledge. The final phase of our proposed system unfolds as we leverage the latent power of the sophisticated deep learning architecture known as vision transformers. The model is finetuned to our specific task and re-learned with the automatically extracted handcrafted features, emerges as a formidable classification framework. As an added layer of refinement, we deploy a majority vote mechanism on image patches, meticulously engineered to heighten system accuracy. Our rigorous testing regimen, carried out on the well-known MPS historical document dataset, has yielded results of remarkable caliber. Our system's prowess is vividly reflected in its performance metrics, boasting an impressive Mean Absolute Error (MAE) of 3.97 for document-level evaluations and a resounding 7.42 MAE for patch-level assessments.

Determining the script of historical manuscripts is pivotal for understanding historical narratives, providing historians with vital insights into the past. In this study, our focus lies in developing an automated system for effectively identifying the script of historical documents using a deep learning approach. Leveraging the ClAMM dataset as the foundation for our system, we initiate the system with dataset preprocessing, employing two fundamental techniques: denoising through non-local means denoising and binarization using Canny-edge detection. These techniques prepare the document for keypoint detection facilitated by the Harris-corner detector, a feature-detection method. Subsequently, we cluster these keypoints utilizing the k-means algorithm and extract patches based on the identified features. The final step involves training these patches on deep learning models, with a comparative analysis between two architectures: Convolutional Neural Networks (CNN) and Vision Transformers (ViT). Given the absence of prior studies investigating the performance of vision transformers on historical manuscripts, our research fills this gap. The system undergoes a series of experiments to fine-tune its parameters for optimal performance. Our conclusive results demonstrate an average accuracy of 89.2 and 91.99% respectively of the CNN and ViT based proposed framework, surpassing the state of the art in historical script classification so far, and affirming the effectiveness of our automated script identification system.

However this progress is frequently accompanied by a number of challenges and unfavorable outcomes. This study aims to uncover ICT difficulties related to smart city infrastructure through an extensive literature review. In addition, a survey was carried out among Saudi nationals to find out what they thought about, anticipated, and worried about in terms of smart city concepts and features. The study also looked at a literature checklist of ICT problems, which included dangers to information security, incompatibilities across systems, privacy concerns, and deficiencies in digital capabilities. Based on the findings it appears that privacy breaches and information security concerns are the most important issues. This is explained by heightened susceptibility and potential, cyberattacks and a pervasive ignorance of the protection of personal data. Because of the anticipated high costs and difficulties with adaption and utilization, the public is concerned about incompatibility between systems and services. Furthermore, older individuals and those with lesser educational achievement have different digital skills.

Bioactive compounds in plants, which can be synthesized using N-arylation methods such as the Buchwald-Hartwig reaction, are essential in drug discovery for their pharmacological effects. Important descriptors are necessary for the estimation of yields in these reactions. This study explores ten metaheuristic algorithms for descriptor selection and model a voting ensemble for evaluation. The algorithms were evaluated based on computational time and the number of selected descriptors. Analyses show that robust performance is obtained with more descriptors, compared to cases where fewer descriptors are selected. The essential descriptor was deduced based on the frequency of occurrence within the 50 extracted data subsets, and better performance was achieved with the voting ensemble than other algorithms with RMSE of 6.4270 and R2 of 0.9423. The results and deductions from this study can be readily applied in the decision-making process of chemical synthesis by saving the computational cost associated with initial descriptor selection for yield estimation. The ensemble model has also shown robust performance in its yield estimation ability and efficiency.
