    abstract = "With the surge of AI-generated content in online spaces, ensuring the authenticity of product reviews has become a critical challenge. This paper addresses the task of detecting AI-generated product reviews in Dravidian languages, specifically Tamil and Malayalam, which present unique hurdles due to their complex morphology, rich syntactic structures, and code-mixed nature. We introduce a novel methodology combining machine learning classifiers with advanced multilingual transformer models to identify AI-generated reviews. Our approach not only accounts for the linguistic intricacies of these languages but also leverages domain specific datasets to improve detection accuracy. For Tamil, we evaluate Logistic Regression, Random Forest, and XGBoost, while for Malayalam, we explore Logistic Regression, Multinomial Naive Bayes (MNB), and Support Vector Machines (SVM). Transformer based models significantly outperform these traditional classifiers, demonstrating superior performance across multiple metrics."
