    abstract = "The rapid spread of misinformation in the digital era presents critical challenges for fake news detection, especially in low-resource languages (LRLs) like Malayalam, which lack extensive datasets and pre-trained models for widely spoken languages. This gap in resources makes it harder to build robust systems for combating misinformation despite the significant societal and political consequences it can have. To address these challenges, this work proposes a transformer-based approach for Task 1 of the Fake News Detection in Dravidian Languages (DravidianLangTech@NAACL 2025), which focuses on classifying Malayalam social media texts as either \textit{original} or \textit{fake}. The experiments involved a range of ML techniques (Logistic Regression (LR), Support Vector Machines (SVM), and Decision Trees (DT)) and DL architectures (BiLSTM, BiLSTM-LSTM, and BiLSTM-CNN). This work also explored transformer-based models, including IndicBERT, MuRiL, XLM-RoBERTa, and Malayalam BERT. Among these, Malayalam BERT achieved the best performance, with the highest macro F1-score of 0.892, securing a rank of 3rd in the competition."
