Research Interests

Dr. Rahman’s primary research interests are Natural Language Processing (NLP), Machine Learning, and Deep Learning. He has experiences in Natural Language Understanding, Information Extraction, Semantic Web and Big Data Analysis. He has a deep passion for investigating and developing new Machine Learning and NLP techniques to understand Behavioral Psychology and Mental Health.

Dr. Rahman’s research mostly focuses on the real-world applications of advanced NLP and Machine Learning techniques. He believes the key to success in life is making contributions to the communities through the use of modern technologies. Over the last 9 years, he has had the opportunities to work with talented researchers from academia and industries, where he has been involved in a variety of interesting research and development problems. These opportunities have helped him work in a team environment and make individual decisions.

Dr. Rahman joined the Technology and Translational Research Unit in October 2019 under the supervision of Dr. Brenda Curtis. Before that he was a Postdoctoral Researcher in the Center for Language and Speech Processing (CLSP) at the Johns Hopkins University (JHU). He intends to continue his research in the fields of NLP and Machine Learning, and plans to extend his research in Health Care, Computational Psychology and Substance Abuse.

As a long-term study, Dr. Rahman would like to contribute to the development of Artificial Intelligence (AI) techniques for predicting important trends in Mental Health from Social Interactions and Geoinformation, developing AI models for identifying Mental Disorders, implementing Deep Reinforcement Learning in Behavioral Psychology & Mental Health, and developing an AI-powered personalized Conversational Assistant that helps patients to access right information about their health symptoms and medications.

If the test collection contains speech documents, additional errors from automatic speech recognition (ASR) makes translation even more difficult. We propose a robust document representation that combines N-best translations and a novel bag-of-phrases output from various ASR/MT systems. We perform a comprehensive empirical analysis on three challenging collections; they consist of Somali, Swahili, and Tagalog speech/text documents to be retrieved by English queries. By comparing various ASR/MT systems with different error profiles, our results demonstrate that a richer document representation can consistently overcome issues in low translation accuracy for CLIR in low-resource settings.},
