This study chronicles the drama played out in universities across the world. Lecturers from varying disciplines and backgrounds attempt to teach subjects using diverse methodologies or no methodology at all. Academia is presently divided into two distinct camps. Those who are in favour of pedagogical training regardless of discipline and believe it enhances and enriches the teaching and learning process and those who simply are not in favour of it. The alarming result has been that in each university, there is no standardization of modules taught or learnt or indeed no formal system of how a module should be delivered to aid module authors and leaders with no requisite pedagogical training. This has increasingly led to falling grades, low retention rates and much disappointment on the part of the raison d' etre of the university, its valued clients - the students. This study seeks to outline the problem, recommend a solution and propose more extensive utilisation of existing technology that could help to alleviate the problem in some way.

For the diagnostics and health management of lithium-ion batteries, numerous models have been developed to understand their degradation characteristics. These models typically fall into two categories:data-driven models and physical models, each offering unique advantages but also facing ***-informed neural networks(PINNs) provide a robust framework to integrate data-driven models with physical principles, ensuring consistency with underlying physics while enabling generalization across diverse operational conditions. This study introduces a PINN-based approach to reconstruct open circuit voltage(OCV) curves and estimate key ageing parameters at both the cell and electrode *** parameters include available capacity, electrode capacities, and lithium inventory capacity. The proposed method integrates OCV reconstruction models as functional components into convolutional neural networks(CNNs) and is validated using a public dataset. The results reveal that the estimated ageing parameters closely align with those obtained through offline OCV tests, with errors in reconstructed OCV curves remaining within 15 mV. This demonstrates the ability of the method to deliver fast and accurate degradation diagnostics at the electrode level, advancing the potential for precise and efficient battery health management.

Software security poses substantial risks to our society because software has become part of our life. Numerous techniques have been proposed to resolve or mitigate the impact of software security issues. Among them, software testing and analysis are two of the critical methods, which significantly benefit from the advancements in deep learning technologies. Due to the successful use of deep learning in software security, recently,researchers have explored the potential of using large language models(LLMs) in this area. In this paper, we systematically review the results focusing on LLMs in software security. We analyze the topics of fuzzing, unit test, program repair, bug reproduction, data-driven bug detection, and bug triage. We deconstruct these techniques into several stages and analyze how LLMs can be used in the stages. We also discuss the future directions of using LLMs in software security, including the future directions for the existing use of LLMs and extensions from conventional deep learning research.

The swift expansion of Low-Power Internet of Things (LP-IoT) devices has significantly impacted industries such as smart homes, healthcare, agriculture, and industrial automation. In these interconnected environments, reliable wireless communication is essential for efficient data transmission. Channel estimation techniques play a crucial role in assessing the state of the wireless channel before transmitting data. While conventional techniques have been developed, they often struggle in dynamic environments due to substantial computational demands and limited adaptability. Recent advancements in Machine Learning (ML) offer promising improvements in wireless channel estimation for LP-IoT by capturing complex relationships and adapting to changing conditions of wireless channel. Considering the ML models as the potential substitute in the field of wireless channel estimation, this paper builds on our previous work by providing a detailed analysis of two advanced ML-based models, which demonstrates their applicability and reliability in practical indoor environments. While these models have shown potential, a comprehensive analysis of their accuracy in expanded environments has been lacking. To address this gap, we conduct a probability analysis to evaluate the models' estimation accuracy and confidence levels, alongside a scalability analysis to assess performance as network size and complexity grow. The results confirm the effectiveness of these ML-based models and provide valuable insights into their suitability for large-scale LP-IoT applications. Ultimately, this study contributes to the advancement of intelligent LP-IoT communication systems by bridging the gap between theoretical research and real-world deployment. © 2013 IEEE.

Robust federated contrastive recommender system against targeted model poisoning attack

Science China(Information Sciences) 2025年第4期68卷 50-65页

Federated recommender systems(FedRecs) have garnered increasing attention recently, thanks to their privacypreserving benefits. However, the decentralized and open characteristics of current FedRecs present at least two ***, the performance of FedRecs is compromised due to highly sparse on-device data for each client. Second, the system's robustness is undermined by the vulnerability to model poisoning attacks launched by malicious users. In this paper, we introduce a novel contrastive learning framework designed to fully leverage the client's sparse data through embedding augmentation, referred to as CL4FedRec. Unlike previous contrastive learning approaches in FedRecs that necessitate clients to share their private parameters, our CL4FedRec aligns with the basic FedRec learning protocol, ensuring compatibility with most existing FedRec implementations. We then evaluate the robustness of FedRecs equipped with CL4FedRec by subjecting it to several state-of-the-art model poisoning attacks. Surprisingly, our observations reveal that contrastive learning tends to exacerbate the vulnerability of FedRecs to these attacks. This is attributed to the enhanced embedding uniformity, making the polluted target item embedding easily proximate to popular items. Based on this insight, we propose an enhanced and robust version of CL4FedRec(rCL4FedRec) by introducing a regularizer to maintain the distance among item embeddings with different popularity levels. Extensive experiments conducted on four commonly used recommendation datasets demonstrate that rCL4FedRec significantly enhances both the model's performance and the robustness of FedRecs.

Diabetes is a long-term illness that results in a variety of chronic body damage, such as kidney failure, heart problems, eye damage, depression, and nerve damage. This disease is caused by several risk factors, the most prevalent of which are age, obesity, hypertension, and insulin resistance. As a result, early detection of these chronic diseases is critical in assisting patients in reversing diabetes and living healthy lives. Moreover, the main motive of this research is to enhance the prediction and classification score of the existing models by improved dimensionality reduction. In this study, a new early diabetic prediction model is developed using a new Three-Layer Classifier model. The proposed model is designed by using the Support Vector Machine (SVM), Random Forest (RF), and Improved Restricted Boltzmann machine (I-RBM). At first, the raw data is pre-processed using a data cleaning method, where the Missing Value handling, Unwanted data removal, and noise and Outliers handling are accomplished. The noisy images are filtered/denoised by median filters. Then, from this pre-processed data, features like improved Independent Component Analysis (i-ICA), information gain, joint mutual information (JMI), conditional mutual information (CMI), Correlation, and Joint entropy are extracted. As a result, the performance of the proposed model can be validated with different existing methods such as IRBM, RF-SVM, RBM, RF, and SVM. The developed system provides better accuracy about 98.7% of disease classification accuracy and it is high when compared with the existing methodologies such as SVM, RF, RBM, RF-SVM, and IRBM. The accuracy of SVM is about 87%, the accuracy of RF is 91%, RBM and RF-SVM models have 95% accuracy, and the IRBM model has 96% accuracy. Moreover, the higher accuracy of the proposed model indicates that the system can able to reduce the high dimensionality data to avoid overfitting and thus it can enhance the perfromance. © The Author(s), under excl

引用

Journal of The Institution of Engineers (India): Series B 2025年第2期106卷 475-486页

The disease that contains the highest mortality and morbidity across the world is cardiac disease. Annually millions of people are affected and deaths take place due to cardiac diseases worldwide. There are various diagnostic measures for the prediction of heart diseases. However, these techniques consist of some errors, delays, and high-cost consumption. These limitations affect the patients in many ways such as inadequate medication during the right time, affecting their mental health, affecting their physical health, and sometimes death. Hence, there is a need for an effective automatic multimodal disease risk prediction mechanism related to heart diseases. Therefore, this paper proposes the Ensemble hybrid recurrent transformer-based random wolf bird (EHRT-RWB) algorithm. The details of the patient acquired as input by the heart disease dataset are preprocessed initially and classification is performed with the EHRT-RWB methodology. The RNN method extracts reliable features and helps to study the temporal sequence data. Time series classifications are maintained with the help of the transformer method and the ensemble method integrates advanced cutting-edge technologies for performance augmentation. Finally, the RWB algorithm selects and tunes the hyperparameters of the developed classification method. Experiments conducted using certain performance assessment measures and the comparison with existing strategies show the method achieves superior cardiac disease detection performance with the highest accuracy score of 98.7%. © The Institution of Engineers (India) 2024.
