Experience
Director, Applied Science
Oct 2017 — Present
I am the head of the Self-learning and End-to-End Routing (SEER) division of 140+ FTE (TPM, Applied Scientist and SDEs) within the Artificial General Intelligence (AGI) org. My team is at the forefront of pioneering self-learning technologies, a critical component in empowering Amazon’s conversational agent, Alexa, to continuously evolve. Their mission includes learning from customer feedback, correcting defects, and tailoring customer experiences through personalization techniques. Recently we are working on enabling self-learning technique for LLM and building a personalized LLM with various personalities. Check out Rohit\'s Lightning talk at re:Invent 2018 about this first disclosure of this effort: & feature=youtu.be & t=966. I also published a blog at: After that, we have developed multiple programs to 1) develop the automatic metric to measure the customer perceived defect rate; 2) enable automatic defect reduction for Alexa through self-learning; 3) use machine agent to annotate customer data to reduce the needs for human annotator; 4) expose levers to our developer to enable them to improve skill quality; 5) democratize the self-learning capability to core Alexa service to improve customer experience. We are also working on new innovations to enable a personalized Alexa to reason and complete the task autonomously. You can check out: & hl=en for the recent publications.
