I also offer a technical due-diligence service in AI to investors in some of the reputed VC firms in the Valley, including Andreessen Horowitz and Bloomberg Beta.
3. Author of a widely-used Deep Learning and NLP book using PyTorch, and author of many highly-cited papers in NLP and Speech.
4. Research Scientist and Individual Contributor at places like Amazon (Alexa early team), Twitter, and Google.
5. Founder of The Fake News Challenge, a non-profit initiative to bring more than 1000 hackers and AI researchers worldwide to work on fact-checking related problems.
