Adi Renduchintala

I am an Applied Research Scientist in the NeMo team at NVIDIA, working on problems in Natural Language Processing. Prior to this, I was a Research Scientist at Facebook AI Research Accel (FAIR Accel). I worked on gounding neural dialogue agents in complex domains (game playing) and also worked on improving Machine Translation of named enitties.

Before that, I was a PhD student in the Center for Language and Speech Processing (CLSP) at Johns Hopkins University. I was advised by Philipp Koehn and Jason Eisner. My primary research is in building computational models for user modeling, specifically in language learning. I apply techniques from Natural Language Processing (NLP), Machine Translation (MT), and Machine Learning (ML) towards this problem. Check out these early prototypes, here and here, to get a sense of the project.

I also have worked with Adam Lopez on finite automata based systems for machine translation and translation using Abstract Meaning Representations (AMR). I’ve also worked with Kevin duh on character-aware NMT modeling as well as an analysis on the effect of Byte-pair encoding on NMT performance. Recently, I’ve worked on a few projects in End-to-End speech recognition with Shinji Watanabe. During my PhD I Interned at Duolingo under the guidance of Burr Settles working on robust word-embedding models and chatbots for language learners.

Before joining CLSP, I worked on designing new modalities of user interaction at the Arts Media & Engineering program. I also worked at Rosetta Stone as a software developer and did a brief stint as an NLP engineer at MModal. See my CV for more details.
