“RaagaDhvani: A novel augmented multi-feature dataset: Advancing emotion recognition in Carnatic music with multimodal features and hybrid deep learning” Mrs. Archana Priyadarshini, Dr. Usha Divakarla Data in Brief, 2026 dataset has been created, focusing on culturally significant, emotion-driven vocal and flute renditions of eleven carefully selected Carnatic ragas, which are chosen for their psychological and affective associations. The dataset comprises 11 classical ragas, each recorded for approximately 5 min in high-quality audio. This approach preserves essential musical features, including gamakas, phrase structures, and tonal motifs, while generating sufficient training samples for deep learning models. The 448 ragas dataset is further enhanced with data augmentation, including pitch shifting, time-stretching, and noise addition. Later, to increase the validity and quality of Carnatic music, self self-curated dataset of 165 files are augmented with pitch shift and time stretch, resulting in 825 files to increase variability and improve model generalization. This dataset establishes a strong foundation for computational analysis of Carnatic music, supporting tasks like raga classification, emotion recognition, and multimodal retrieval. By integrating audio features with emotion annotations, it advances deep learning-based emotion prediction and fosters applications in psychology and music therapy.
Utilizing Artificial Intelligence for the Identification of Plant Species and Detection of Diseases through Deep Learning Usha Divakarla, K. Chandrasekaran, Srihari Govindarajan, Sivaramakrishnan Sangameswaran Decision Sciences in Bioinformatics Theory and Practice, 2026 Utilizing deep learning for the identification of plant species and the detection of diseases is crucial in mitigating the impact of these diseases on plant growth and crop yield. Early diagnosis is key to preventing losses and enhancing the overall quality and quantity of agricultural products. While various machine learning models have been employed for disease detection, the advent of deep learning has significantly increased the potential for improved accuracy in this research domain. Our proposed system aims to identify both the plant species and diseases affecting the leaves. A test database containing various plant diseases was established to assess the accuracy of our model. Training the classifier with the obtained data allows for more accurate predictions. We employed the GoogleNet model, which incorporates different layers designed to predict diseases effectively. In contrast to the conventional method where farmers rely on visual inspection and their knowledge of plant diseases, our system offers a more efficient and accurate alternative. Large-scale manual inspections are time-consuming, challenging, and often lack precision. Seeking expert consultation incurs substantial costs. To address these challenges, we implemented techniques involving automatic disease detection devices, enhancing accuracy while reducing costs and simplifying the process. This review comprehensively elucidates the utilization of deep learning models for visualizing various plant diseases. Additionally, it highlights research gaps, aiming to bring greater clarity to the early detection of plant diseases, even before symptoms become apparent.

A Comprehensive Framework for Safeguarding Big Data Applications Against Ransomware Attacks Usha Divakarla, K Chandrasekaran Proceedings of IEEE International Conference for Women in Innovation Technology and Entrepreneurship Icwite 2025, 2025 Big data systems are essential in applications like business intelligence, predictive analytics, and machine learning, but their vast repositories of sensitive information make them prime targets for ransomware attacks. Ransomware encrypts data, demanding a ransom for its release, and traditional countermeasures often fail to mitigate its impact effectively in big data environments due to performance overheads or vulnerabilities to advanced attacks. This paper proposes a robust framework to defend big data applications against ransomware. The approach leverages entropy-based dynamic detection to identify ransomware through anomalous write patterns, complemented by machine learning techniques to classify potential threats. By identifying and securing the most vulnerable servers, the framework minimizes performance degradation while ensuring enhanced protection. Additionally, privilege-escalation attacks are mitigated through randomized security identifiers, and backup systems are augmented with ransomware detection to provide a comprehensive recovery mechanism. Experimental results and analyses of existing methods reveal the framework's ability to balance high-security standards with optimal system performance, addressing key challenges such as zero-day attacks, partial encryption risks, and recovery downtimes. This multi-layered defense strategy ensures that big data systems can maintain their critical operations while mitigating the growing threat of ransomware. The proposed solution paves the way for further enhancements in securing large-scale, distributed data environments)
Analyzing Political Bias in Indian News Articles using NLP and Deep Learning Chandrasekaran K, Usha Divakarla, Jeet Nilesh Desai Proceedings of the 2025 International Conference on Artificial Intelligence and Emerging Technology Global AI Summit 2025, 2025 Concerns about fairness in journalism have grown with the rise of politically biased content, especially in countries like India. This study introduces a novel sentiment-informed clustering framework that scales political bias scores across six levels for Indian news, enabling more fine-grained bias detection than existing binary or ternary approaches. A custom-labeled dataset is created and transformed it into a multi-class classification task. We evaluated traditional machine learning models (Logistic Regression, SVM, Naïve Bayes, Random Forest) and deep learning models (BERT, RoBERTa, BiLSTM with RoBERTa embeddings). BiLSTM with RoBERTa embeddings achieved the highest accuracy of 96.91%. The study demonstrates a reliable approach for detecting political bias in news articles, contributing to efforts toward more transparent and balanced journalism.
A Sustainable Model of Security Automation: Approach and Analysis Chandrasekaran K, Aditya Rathod, Usha Divakarla 2025 IEEE International Conference on Recent Advances in Computing and Systems Reacs 2025, 2025 Cybersecurity defenses must evolve as threats grow more complex and compliance requirements tighten. Traditional rule-based IDS and SIEM platforms often incur high false-positive rates and energy costs [1], [2], making long-term operation unsustainable. We propose an integrated security automation framework that embeds sustainability at its core. Our model combines AI-driven anomaly detection [2] for real-time threat identification, federated learning for privacy-preserving intelligence sharing [3], blockchain-based tamper-evident logging [4], and post-quantum cryptography to future-proof communications [6]. The architecture automates compliance with standards (e.g. NIST CSF, ISO/IEC 27001) and optimizes processing to minimize resource usage. Preliminary case studies in finance and healthcare demonstrate that this approach maintains high detection accuracy while significantly reducing false positives and energy consumption [5]. Overall, our sustainable security automation model enhances resilience and transparency without sacrificing efficiency [1], [5].
USING JIFF FOR COLLABORATIVE MEDICAL DATA ANALYSIS WITH SECURE MULTIPARTY COMPUTATION Usha Divakarla, K Chandrasekaran, K Hemanth Kumar Reddy Proceedings on Engineering Sciences, 2025 In collaborative data analysis, secure multiparty computation can be utilised to compute statistical functions in a private manner. For the purpose of developing apps that require safe multi-party collaboration, JIFF is an open-source JavaScript library. We use JIFF to create an application that allows two parties to collaborate on medical data analysis, including the processing of sensitive patient data while maintaining data confidentiality and privacy. A decentralized system that ensures data security and secure computation of private information is provided by the JIFF framework. We assess the system's functionality and privacy-preserving skills, proving that it can effectively protect data privacy while still producing reliable analysis findings.
Skin Cancer Detection using Deep Learning Usha Divakarla, Nikhil R Chandan, Poorva S P, Ranjan Shettigar, Pratham G Nayak 2025 International Conference on Artificial Intelligence and Data Engineering Aide 2025 Proceedings, 2025 Skin cancer becomes one of the various cancers most frequently diagnosed in most people around the globe; early diagnosis has always led to successful treatment. Deep learning techniques have shown to be useful for automated skin cancer detection from dermoscopic images. Here, we present a whole approach involving deep learning and machine learning features that can be used accurately for the efficient detection of skin cancer. We would work on building a highly functional deep learning model. The model would be trained on a large dataset of dermoscopic images that would feature various forms of skin lesions. Deep learning models, based on CNN technology, can capture minor features that present in an image; this therefore makes differentiation between malignant and benign lesions easier.
