About Me

I am a Graduate student of Computer Science at Pondicherry Central University. Prior to joining the Department of Computer science at Pondicherry, I was a student of Bachelor of Science in Computer Science at Ramakrishna Mission Vivekananda Centenary College. My research interest is in the field of Computational Social Science and Natural Language Processing. Currently I am working as a Research Assistant at the Department of Computer Science, Ashoka University(Sonipat) under the guidance of Dr. Anirban Sen. I did my schooling at Ramakrishna Mission Vidyapith, Purulia. My hobby is reading story books(short stories, historical fiction) and watching football matches(culé).

Project

Code-mixed Sarcasm Detection of Large Language Models

Large Language Models are capable of doing almost everything that we need in our day-to-day lives, yet they perform poorly when it comes to basic tasks such as sarcasm detection in code-mixed sentences. Comparatively a transformer-based language model such as DistilBERT performs quite well if it is fine-tuned on code-mixed sarcasm data in detection tasks.

Automated Answer Script Evaluation

Answer script evaluation is a very tedious job which is subject to various human biases. This project was aimed to develop an automated system based on NLP to predict score for answers to broad-answer-type questions.
