Rishabh Singh

I am a research scientist in the Google Brain team, where we work on developing new deep learning architectures for learning programs and program analysis. I develop new program synthesis techniques for helping end-users, students, and programmers. Apart from research, I enjoy playing bridge.

I am currently deeply interested and excited about developing neural architectures for program representations and using them for program synthesis, repair, and security. Some of our latest work in this area:

My research aims to democratize programming for end-users and students. Towards this goal, I develop systems using program synthesis techniques to make programming more accessible to end-users, students, and even programmers. Some research projects that I am actively working on include:

Data Wrangling for End-users

These systems help data scientists and end-users perform data wrangling (cleaning, transformation, and integration) tasks easily using input-output examples, without writing complex programs/scripts.

Semi-supervised learning of data transformations from both input-output examples and the input data. 1000x faster than FlashFill and learns richer transforamtions!
