After a great summer at Microsoft Research Redmond, I am excited to be at the new Cornell Tech Campus.

Update: Tutorial on Markov Decision Process Theory and Reinforcement Learning [Part 1] [Part 2] [Blog]

Research and Publication

Research Interest: Situated Natural Language Understanding, Semantics, Semantic Parsing, Dialogue Modelling, Reinforcement learning.

I develop machine learning models for mapping natural language to meaning representations (e.g., Misra et al. 2016). I am particularly interested in natural language grounding problems e.g., robot natural language understanding (Misra et al. 2017, 2015a, 2015b, 2014), conversation modeling etc.


Conference and Workshops

Reinforcement Learning for Mapping Instructions to Actions with Reward Learning (NCHRC, AAAI Fall Symposium 2017)
Dipendra K. Misra and Yoav Artzi
Punchline: Learn a reward function directly on images for mapping natural language instructions to actions.
[Paper To Come] [Code]

Mapping Instructions and Visual Observations to Actions with Reinforcement Learning (EMNLP 2017)
Dipendra K. Misra, John Langford and Yoav Artzi
Punchline: We present an approach for mapping natural language instructions and visual observations to agent actions using reinforcement learning.
[Paper] [Code] [Arxiv Preprint]

Neural Shift-Reduce CCG Semantic Parsing (EMNLP 2016)
Dipendra K. Misra and Yoav Artzi
Punchline: We present the first published shift-reduce parser for CCG semantic parsing. Our novel learning algorithm considers learning without annotated parse trees, with type constraints and complex categories.
[Paper] [Supplementary] [Code]

Environment-driven lexicon induction for high-level instructions (ACL 2015)
Dipendra K. Misra, Kejia Tao, Percy Liang, Ashutosh Saxena
Punchline: Learning new concepts and meaning of new verbs at test time using environment as an implicit signal.
[Paper] [Supplementary] [Code] [Data] [Simulator] [Bibtex]

Tell Me Dave: Context-Sensitive Grounding of Natural Language to Manipulation Instructions (RSS 2014)
Dipendra K. Misra, Jaeyong Sung, Kevin K. Lee, Ashutosh Saxena
Punchline: Grounding language to actions with application on PR2 robot. Learn from users playing with simulations.
