Dipendra Misra

I will be starting as a researcher at Microsoft Research, New York. I received my PhD in computer science from Cornell University (2019) and my bachelors in computer science from Indian Institute of Technology Kanpur (2013).

Research Interests: I am interested in developing models and learning algorithms with emphasis on applications in natural language understanding. For example, building agents that can follow instructions, answer questions or hold a conversation. I am currently active in the following research areas: grounded natural language understanding, language and vision problems, semantic parsing, deep reinforcement learning, reinforcement learning theory and model based learning. Over the past few years, my focus has shifted more towards developing theoretically sound methods for real-life problems.

Research and Publication

I am interested in developing models and learning methods with emphasis on applications in natural language understanding such as robots that can follow instruction, answer questions or hold a conversation. I am currently active in three research areas:

  • Robot Instruction Following: Robots that can follow instructions can be of great assistance. I am interested in developing models that can train with minimal effort and generalize to new environments and instructions. See Misra et al. EMNLP 2018b, EMNLP 2017, ACL 2015a, IJRR 2015b, RSS 2014.

  • Semantic parsing: I am interested in developing semantic parsers using weak supervision with application to tasks like question answering. See Misra et al. EMNLP 2018a and Misra and Artzi EMNLP 2016.

  • Reinforcement Learning: Problems described above are often best described using a reinforcement learning framework. I am interested in developing reinforcement learning algorithms that simultaneously achieve good exploration, sample efficiency and generalization with theoretical guarantees. See Misra et al. EMNLP 2017 and Asadi, Misra, Littman ICML 2018.

I have served or serving as program committee member for natural language processing (EMNLP, ACL, EACL, NAACL), machine learning (ICML, NIPS, AISTATS) and robotics conferences and journals (JAIR, ICRA, HRI, ISRR, RSS).

Misc

I received my bachelors degree in computer science from the Indian Institute of Technology, Kanpur where my undergrad thesis on learning to solve IQ questions was advised by Amitabha Mukerjee and Sumit Gulwani. My studies at time have been supported by OPJEMS Merit scholarship (2011-12 and 2012-13), Cornell University Fellowship (2013) and amazon AWS Research grant (2016). I try to spend some time playing piano, writing compositions and reading news.
