Theedhum Nandrum is a sentiment polarity detection system using two approaches–a Stochastic Gradient Descent (SGD) Classifier and a Recurrent Neural Network (RNN) Classifier. Our approach utilises language features like the use of emoji, choice of scripts and code mixing which appeared quite marked in the datasets specified for the Dravidian Codemix - FIRE 2020 task. The hyperparameters for the SGD were tuned using GridSearchCV on the training data supplied. Our system was ranked 4th in Tamil-English with a weighted average F1 score of 0.62 and 9th in Malayalam-English with a score of 0.65. Our code is published in github at https://github.com/oligoglot/theedhum-nandrum.
