About me

Hi, I am a first year CS PhD student at George Mason University. My research experience is in the domain of Fairness and Bias in Language models. I am also very interested to explore the reasoning capabilities of Large Language Models.

My undergraduate thesis was under Dr Rifat Shahriyar. In the thesis, our goal was to detect gender bias in Bangla Language Models. Based on our thesis work, we have published a paper titled An Empirical Study on the Characteristics of Bias upon Context Length Variation for Bangla which was accepted for poster presentation in the Findings of ACL 2024.

Research & Publications


  1. An Empirical Study on the Characteristics of Bias upon Context Length Variation for Bangla

    Jayanta Sadhu, Ayan Antik Khan, Abhik Bhattacharjee, Rifat Shahriyar Accepted at ACL 2024 (Findings) Same contribution as 1st author Bias and Fairness, Low-Resource NLP [Preprint] [Proceedings] Undergraduate Thesis under the supervision of Dr Rifat Shahriyar. In this study, we investigate gender bias in Bangla, a low-resource language, by creating a specialized dataset and adapting existing bias measurement methods to fit the linguistic context. Our research highlights the significant impact of context length variation on bias metrics, a factor previously overlooked in bias studies. Through our experiments, we demonstrate the necessity for nuanced considerations in Bangla bias analysis. Our work serves as a foundational step towards comprehensive bias measurement in Bangla, with all resources made publicly available to support future research.

  2. Multi-ToM: Evaluating Multilingual Theory of Mind Capabilities in Large Language Models

    Jayanta Sadhu, Ayan Antik Khan, Noshin Nawal, Sanju Basak, Abhik Bhattacharjee, Rifat Shahriyar Under Review for COLING 2025 Same contribution as 1st author LLM Reasoning, Theory of Mind, Multilingual NLP [Preprint] Research project with BUET CSE NLP Group. In this study, we explore the cognitive reasoning abilities of Multilingual Large Language Models within the domain of Theory of Mind (ToM). Our research incorporates cultural elements into ToM tasks, capturing the social and cognitive scenarios unique to various cultural contexts.

Projects

  • Grammatical Error Detection and Correction in Bangla

    Bangla-GED

    View on Github

    Pytorch, Huggingface, Sklearn

    Term Project for CSE 472: Machine Learning Sessional (CSE Department, BUET). This project focuses on detecting and correcting grammatical errors in Bangla sentences. To achieve this, we create a dataset by synthetically introducing error in a newspaper datset. Achieved 93% accuracy in detecting incorrect Bangla sentences by incorporating Sequence Tagging with BanglaBERT and a sacreBLEU score of 90 for sentence correction and auto-completion using BanglaT5.

  • Vectorized Convolutional Neural Network (CNN) from Scratch

    Numpy

    A vectorized implementation of a Convolutional Neural Network using numpy without any deeplearning frameworks. Training and testing of the developed model is done on the NumtaDB: Bengali Handwritten Digits dataset. This was the final assignment of the CSE 472: Machine Learning Sessional course offered by CSE Department, BUET.

  • Notabene: A browser based knowledge management tool
