A comprehensive approach to fetal health prediction using preprocessing and classification Valliammai Ramanathan, Balika J. Chelliah Progressive Computational Intelligence Information Technology and Networking, 2025 The main focus of this paper is to enhance the interpretation of cardiotocography (CTG) data, which is used to identify fetal discomfort during pregnancy by tracking the heart rate of fetus and contraction of uterine. To ensure the validity of classification models used to evaluate fetal well-being, effective pre-processing is essential. The research uses methods that minimize noise while maintaining significant signal characteristics, such as the Savitzky-Golay and median filters for smoothing and linear interpolation for addressing missing data. This work uses cost-sensitive learning to solve the issue of minority classes that are underrepresented in CTG data. In order to emphasize accurate identification of critical categories such as “suspected” and “pathological,” the model assigns larger misclassification costs to these. This ensures improved classification performance in these critical circumstances.
Detecting Re-Entrancy Attacks in Ethereum via Dynamic Tracing Preethy Jemima P, Balika J Chelliah 2025 IEEE 7th International Conference on Computing Communication and Automation Iccca 2025, 2025 One of the most promising technology of blockchain still suffers from multiple attacks. Attack detection is handled by various technologies to enhance the security. Hackers moto is to steal the digital currency here the discussion is of the digital currency Ethereum which also has suffered from the famous attack Re-entrancy attack. Though the usage of smart contact is highly believed by users, making the function to be called again and again leads to this kind of attack. Re-entrancy attacks pose a persistent threat to Ethereum smart contracts, enabling malicious users to repeatedly call vulnerable functions before the state variables are correctly updated. While traditional approaches rely heavily on symbolic execution and SMT solvers for vulnerability detection, these methods suffer from scalability and precision limitations. A novel hybrid framework that integrates dynamic execution tracing with AI-driven classification models, such as Quantum Neural Networks (QNN), for the robust detection of re-entrancy attacks. The system leverages taint analysis and runtime monitoring to generate behavioral features, which are then used to train and evaluate machine learning models. Experiments conducted on benchmark datasets demonstrate superior accuracy and reduced false positives when compared to conventional static analysis techniques, showcasing the effectiveness of combining dynamic and AI-based strategies for smart contract security.
Multilingual language classification model for offensive comments categorisation in social media using HAMMC tree search with enhanced optimisation technique B. Aarthi, Balika J. Chelliah International Journal of Computational Science and Engineering, 2025 The exponential rise of social media platforms has led to a surge in offensive content, highlighting the necessity for effectively detecting and managing such comments. This necessitates precise and advanced online social networks (OSN) categorisation and optimisation methods. This study introduces and assesses a novel technique for automatically categorising texts, supporting over 60 languages, without relying on a pre-annotated dataset. The technique employs multilingual methods based on the randomised explicit semantic analysis (ESA) strategy. To combat the inherently multilingual nature of social media content, the paper introduces an innovative classification and optimisation strategy named 'hybrid adaptive Markov chain Monte Carlo tree search (HAMCMTS) with enhanced eagle Aquila optimiser (EEAO)'. The study uses three publicly available datasets to identify negative or offensive comments in various languages, offering a comprehensive analysis in this field. The proposed approach holds potential for diverse applications, particularly in multilingual categorisation tasks like monitoring disaster-related communications on social media to improve visibility and trust. Moreover, it incorporates a sophisticated mechanism to bolster the dependability of its recommendations.
An approach Towards Ocular Disease Impact Analysis Using One Shot Detector Meivezhi G D, Balika J Chelliah 2025 2nd Asia Pacific Conference on Innovation in Technology Apcit 2025, 2025 Diabetes is a prevalent chronic condition that significantly impacts patients' daily lives and can lead to damage to vital organs over time. While it cannot be cured, proper care is essential to mitigate its adverse effects. Regular visits to healthcare professionals are crucial to ensuring diabetics receive appropriate care. The existing challenges in Diabetic retinopathy detection and evaluation is towards the lack of appropriate dataset and quality of dataset. However, there is a need for innovative approaches to empower individuals with diabetes to manage their blood sugar levels proactively without constant doctor visits. The proposed method aims to address this challenge by employing predictive techniques to enable self-monitoring of blood sugar levels. The primary objective of the suggested approach is to alleviate the burden of frequent physician visits and diagnostic centre appointments. It utilizes deep predictive neural networks and advanced algorithms to analyse data related to retinopathy, a common complication of diabetes. The proposed algorithm is employed to identify retinal abnormalities, while the histogram and GLCM Gray co-matrix is utilized to extract relevant features from the data. Subsequently, a Deep Predictive Neural Network (DPNN-OSD) based One-shot detector (OSD) is developed which is employed for classification tasks. The effectiveness of the model is evaluated using metrics such as accuracy, precision, recall, and confusion matrix analysis. To validate the model and anticipate potential issues, various experimental inputs are provided to the system. By integrating predictive analytics and machine learning techniques, the proposed approach aims to empower individuals with diabetes to monitor their condition effectively and intervene early, when necessary, thereby improving their overall health outcomes.
Real-Time Smart Meeting Assistant Using Edge AI for Audio Capture, Speech-to-Text Conversion, and Meeting Scheduling A Senthilselvi, Mohammad Saquib Daiyan, Mosaab Ahmad, Rajul Mishra, Pakshal Tata, Balika J Chelliah 2025 2nd International Conference on Computing and Data Science Iccds 2025, 2025 This research presents a novel approach to enhancing meeting productivity through the integration of edge AI, cloud-based transcription, and real-time scheduling. Using a Seeed Studio XIAO ESP32S3 Sense device for continuous audio recording, the system sends two-minute audio chunks to a FastAPI backend for transcription using speech-to-text models. Following transcription, the text is processed by a Tiny LLaMA model to extract meaningful insights, such as action items, summaries, and key decisions. Additionally, speaker diarization is applied to differentiate speakers, improving the clarity of transcripts. The system integrates with Google APIs for automatic event scheduling and meeting reminders. This research explores the design, implementation, and evaluation of this intelligent meeting assistant, with an emphasis on accuracy, scalability, and real-time performance. Experimental results demonstrate that the system achieves a Word Error Rate (WER) of 7.3% for transcription in quiet environments, 89.5% accuracy in speaker diarization for meetings with up to 6 participants, and extracts relevant action items with 85.7% precision. The end-to-end system latency averages 3.2 seconds for processing a 2-minute audio segment, making it suitable for real-time applications. User satisfaction surveys indicate a significant 37% improvement in meeting productivity and a 42% reduction in post-meeting administrative tasks.
Enhancing Cervical Cancer Detection: Explainable AI and Attention Mechanisms for Pap Smear Classification Balika J Chelliah, Sarghi Kaur Gahra, M. Shrinidhi, S. Yamini Devi, A. SenthilSelvi, P. Meenalohchini 2025 8th International Conference on Circuit Power and Computing Technologies Iccpct 2025, 2025 Cervical cancer is the second most prevalent female cancer in India, responsible for almost $\mathbf{1 8. 3 \%}$ of all cancers in women, with more than 120,000 new cases every year. Though preventable and curable at early ages, poor availability of skilled cytopathologists and late diagnosis remain the causative factors of high mortality. Conventional approaches to diagnosis heavily depend on Pap smear slide manual screening, which is time consuming, subjective, and prone to errors, particularly in resourcescarce areas. To address these challenges, this study proposes an attention-based and explainable deep learning architecture for cervical cell classification. The architecture is constructed over the EfficientNet-B0 backbone for strong feature extraction, supplemented with a Convolutional Block Attention Module (CBAM) to highlight clinically important features by using improved channel-wise attention. The system has an extensive preprocessing pipeline including image resizing, denoising, Otsu’s thresholding, morphological operations, and color normalization to provide quality input data. The model is trained on a curated dataset comprising both cancerous and normal cervical cytology images. Post-hoc explanation methods such as Grad-CAM++, SHAP, and LIME are used for explaining and justifying the predictions made by the model. The proposed method attains an accuracy of 82%, a sensitivity of 80.6%, specificity of 83.1%, and an AUC score of $\mathbf{0. 8 7}$. This work emphasizes the potential of explainable deep learning systems to aid early and accurate cervical cancer diagnosis, particularly in underserved healthcare environments.
A Decentralized Cloud-Based Approach to Enhancing EHR Security with Blockchain and Dual Encryption A Senthilselvi, M Eyadu Nandhan, R Kishore, M Charan, Balika J Chelliah, S. SenthilPandi Proceedings of 3rd IEEE International Conference on Knowledge Engineering and Communication Systems Ickecs 2025, 2025 With the widespread support of Electronic Health Records (EHRs) in the medical field also comes a realistic worry of the need to secure this information from unauthorized access. In traditional electronic health record management systems, centralized system approach puts up at risk of data invasions, mainly patient records which are very delicate and confidential. This paper describes an efficient cloud-based file sharing system for the storage and management of EHRs that takes advantage of cloud computing and blockchain technologies. The presented method implements dual-layer encryption which includes Elliptic Curve Digital Signature Algorithm (ECDSA) and Secured Hashing Algorithm-256 (SHA-256) hashing to assure the authenticity, integrity and confidentiality of the EHRs. The use of a blockchain approach within the system bounds allows for elimination of even servers thereby enhancing how the information integrity is preserved. The electronic health records management system proposed in this paper eliminates the major concerns of data integrity associated with client-server-based systems and overcomes hematogenic challenges through maintaining patients’ associate’s privacy even as threats evolve in the CS world.
