Deepak Gupta

3rd-year Ph.D. Student
Indian Institute of Technology Patna, India

My research aims at developing sophisticated system which can understand the natural language and take intelligent decision - more focussed on question answering, machine reading comprehension and conversational agents problem. I have worked semantic natural language question matching, answer sentence selection and answwer triggering. I am working on complex answer extraction/generation, deep learning based generative conversational agents and multi-lingual question answering system. I am very excited to learn about multimodal question answering in multilingual settings.

I am advided by Prof. Pushpak Bhattacharyya and Dr. Asif Ekbal.
