Experience

Worked on Modality importance guided Document Understanding:
Diagnosing Evidence Utilization in Multimodal Document Question Answering: This paper conducts a comprehensive diagnosis of how effectively 7 popular Multimodal Large Language Models (MLLMs) use relevant evidence for document question answering across text, image, table, chart, and cross-modal inputs. Results reveal a strong reliance on text-based evidence, with notably weaker performance on image-only and cross-evidence inputs, a gap that supervised fine-tuning also fails to consistently close. Attention-based analysis further shows that low attention to image tokens contributes to poor utilisation of image evidence, highlighting the key limitations in current MLLMs. Accepted at SIGKDD'26.
Mentors: Dr Digbalay Bose and Dr Koustava Goswami.
