Abstract-Predictive mathematical models of biological processes like wound healing are essential for quantitative understanding, but their clinical utility is often limited by a critical roadblock: uncertainty in their biophysical parameters. These parameters are difficult to measure directly and must be inferred from sparse, noisy data. This paper presents a Bayesian Physics-Informed Neural Network (BPINN) framework to address this challenge by performing robust parameter inference and principled uncertainty quantification. We frame the identification of unknown parameters in a coupled reaction-diffusion system for wound healing as a Bayesian inverse problem. By integrating sparse observational data with the governing physical laws within a variational inference framework, the BPINN learns the full posterior distributions of unknown model parameters. Our results show that the framework accurately infers key reaction parameters from a dataset comprising less than 0.01% of the full spatio-temporal domain. More importantly, the BPINN correctly diagnoses that the cell motility parameter is practically non-identifiable from the sparse data, a conclusion supported by the large posterior uncertainty it assigns. The model’s predictive uncertainty is well-calibrated, being highest in regions far from observations. This work establishes the dual value of BPINNs as a powerful computational tool: both for developing reliable, personalized biomechanical models through data-driven calibration, and for diagnosing parameter identifiability issues—a critical step towards building trustworthy models in computational medicine and systems biology.

Abstract: Knee injuries, prevalent in athletic and aging populations, pose significant challenges to healthcare professionals due to their complex nature and the critical function of the knee joint. Early and accurate diagnosis is paramount to ensure effective treatment and minimize long-term complications. Traditional diagnostic methods, including physical examinations and imaging techniques like MRI, require expert interpretation and can sometimes be inconclusive. This study introduces an approach to knee injury classification using deep learning techniques by leveraging convolutional neural networks (CNNs) with Attention Mechanism. This research work integrates powerful feature extraction capabilities of CNN and feature refinement of attention mechanism for the binary and multi-class classification of knee MRI images, with the aim of accurately identifying specific knee injury types. Based on our experiment on two comprehensive knee MRI datasets, our custom CNN model achieved 88% testing accuracy on Dataset-1 (Binary classification) and 77% accuracy on Dataset-2 (Multi-class classification). Meanwhile, the Attention-based CNN model achieved 100% accuracy on Dataset-1 (Binary Classification) and 91% accuracy on Dataset-2 (Multi-Class Classification). This approach not only holds promise for enhancing diagnostic accuracy but also for reducing the time to diagnosis.

Abstract—Natural language processing (NLP) has witnessed significant advancements in recent years, particularly in improving question-answering (QA) systems for well-resourced languages such as English. However, the development of such systems for low-resource languages, including Bengali, remains insufficiently explored. This study proposes an approach to developing a Bengali QA system utilizing the Llama-3.2-3B-Instruct model, leveraging transfer learning techniques on a synthetic dataset derived from the SQuAD 2.0 benchmark...

Abstract—The Bengali language, rich in history and cultural significance, poses unique challenges in Natural Language Processing (NLP) due to its dual-register structure: Sadhu (formal) and Cholit (colloquial). These registers differ significantly in syntax, vocabulary, and usage, complicating tasks such as text classification, translation, and sentiment analysis...

Abstract—Enhancing interpretability without compromising accuracy is a critical challenge in text classification. This re- search explores the integration of Explainable Artificial In- telligence (XAI) techniques with advanced machine learning models, utilizing the Local Interpretable Model-Agnostic Expla- nations (LIME) framework to provide transparency. A fine-tuned BERT model achieved state-of-the-art performance, surpassing Random Forest and Sentence Embedding-based models with a perfect 100% accuracy (ROC-AUC score of 1.00). While Random Forest classifiers offered a solid baseline, they struggled with semantic nuances, underscoring the need for embedding- based approaches. The study highlights the inherent trade-off between interpretability and accuracy, demonstrating that while transformer-based models like BERT excel at capturing complex linguistic patterns, their ”black-box” nature necessitates tools like LIME for explainability. By bridging this gap, the research contributes to the development of more transparent, reliable, and high-performing AI systems.

Abstract—This paper presents a novel approach to real-time anomaly detection in power system dynamics using Physics-Informed Neural Networks (PINNs). The proposed method integrates domain-specific physical constraints with deep learning techniques to enhance the accuracy and reliability of anomaly detection in critical power infrastructure. By incorporating the underlying physics of power system dynamics, the model achieves superior performance compared to traditional machine learning approaches, particularly in scenarios with limited training data and complex system behaviors.
