COMPARATIVE ANALYSIS OF TRANSFORMER MODELS FOR SENTIMENT CLASSIFICATION IN CODE- MIXED INDIC LANGUAGES

Mohana Priya K.T, Shrinithi G, Nithish P, Pranesh A C — Tue, 25 Mar 2025 00:00:00 +0000

Multiple language usage in a single message, or code-mixed text, has increased dramatically as a result of increased social media engagement. Because of this, activities involving Natural Language Processing (NLP), such as sentiment analysis and cyberbullying identification. Models that can effectively manage linguistic variability while retaining high accuracy are needed to address these issues. We investigate transformer-based designs that improve classification performance by utilizing knowledge transfer strategies. RoBERTa, GPT-2, XLM-RoBERTa, and IndicBERT are used in our method, which enhances classification accuracy by the transfer of sharing-private information across code-mixed and monolingual tasks. Results from experiments show that our multi-task framework surpasses single-task models with high accuracy on all datasets with:IndicBERT achieved 96.86% for Hinglish, XLM-RoBERTa achieved 96.95% for Punglish, and IndicBERT obtained 97.55% for Tanglish. In order to advance reliable NLP applications in multilingual environments, this project highlights the transformers' multi-task learning capabilities in enhancing performance on low-resource and code-mixed languages.

TWO-STAGE DC-DC ISOLATED CONVERTER FOR EV BATTERY CHARGING WITH AI CONTROLLER

M Amuthanantham, M Bharath, Sai kumar, S Mahaboob Basha — Tue, 25 Mar 2025 00:00:00 +0000

The Electric vehicles (EVs) require efficient and reliable charging systems to optimize battery performance and lifespan. Traditional converters, however, face limitations in meeting these demands, especially under dynamic charging conditions. This project presents a novel approach to EV battery charging using an AI-controlled two-stage DC-DC isolated converter, enhanced with an artificial neural network (ANN) for real-time optimization. The proposed system utilizes a two-stage converter architecture, where the first stage boosts the input voltage, and the second isolated stage provides galvanic separation, ensuring safe and efficient power transfer to the EV battery. An ANN- based controller dynamically adjusts the converter parameters based on input voltage, battery state-of-charge (SOC), and output current. This intelligent control minimizes energy losses, improves voltage regulation, and reduces thermal stress on the converter components, leading to enhanced system efficiency. Simulation results indicate that the ANN controller adapts effectively to varying input conditions, maintaining optimal charging rates while safeguarding battery health. This AI-driven approach offers a promising solution for fast, efficient, and adaptive EV battery charging, aligning with the increasing demand for smart and sustainable transportation technologies.

Efficient campus parking management is needed to minimise congestion, wastage of resources, and delays caused to students, staff, and visitors. The study focused on applying machine learning techniques to improve parking management systems using real-time data analysis. Such ML techniques comprise decision trees, SVMs, and neural networks developed through cameras and sensors for predicting parking availability, optimising resource allocation for multiple locations, and directing vehicles to them. The system dynamically adapts to varying traffic conditions, load levels, and periods of the day to allow further optimisation of space usage and improved mobility. Besides other advantages, predictive analytics endorses strategic infrastructure planning and improves operational efficiency. In essence, the findings of the study prove that the ML solutions for parking will enhance both campus mobility and traffic congestion during peak hours, thus encouraging sustainability.

SECURIG HEALTHCARE DATA IN THE CLOUD AGAINST INFERENCE ATTACKS

G. Vishnupriya, Adishwar A, Chandru S, Dinesh S — Tue, 25 Mar 2025 00:00:00 +0000

The E-HealthCare cloud system demonstrates important possibilities for improving healthcare quality and the well-being of people. However, it has not spread, especially due to the most important concerns about security and privacy. Existing methods for storage rely on basic access control models and are susceptible to inference attacks. In this article, we have set up an inference attack for attacks on e-HealthCare cloud systems that use fine-tuned access controls. We propose a new approach using a two-layer encryption scheme that allows for secure and effective data manipulation. The first encryption layer contains marked access guidelines. This can be tailored to any data attribute where fine access control is achieved and encryption efforts are reduced simultaneously. As a rule, role attributes and access guidelines are hidden within a second encryption layer to protect privacy. The cloud is permitted to perform a variety of mathematically intensive tasks on behalf of the user without disclosing private data, in order to use the computing power of the cloud without affecting the confidentiality of the sensitive information. To achieve this, we develop a blind data access protocol using Paillier encryption. The results of comprehensive security analysis and performance assessments confirm that the proposed solution is as efficient and efficient as a secure cloud management system.
