Jayaprakash Sundararaj

I am a Senior Software Engineer at Google USA, specializing in search ranking and personalization projects. My work focuses on developing and training deep learning models and leveraging large language models (LLMs) for selected initiatives. Additionally, I play an active role in hiring, onboarding, and mentoring engineers, fostering a culture of growth and excellence within the team. Notably, I launched: [1] Fact checking articles in Google News and Google Web Search, [2] On-Device Univeral Search in Pixel System Intelligence team, and [3] Query recommendations in Play Store Search Home.

I have a post-graduation degree in CSE from IIT Bombay, India & ungraduate degree in IT from Anna University, Chennai.

Previously, I have worked in Yahoo! Research, and Alcatel Lucent Labs.

Interests

I enjoy working in applied research problems, and building usable projects leveraging state of the art machine learning models. Lately, I'm focused on pursing interpretability and explainablity aspect of maching learning research.

Projects

• [Google] Query recommendations in Play Search Home
• [Google] On-Device Universal Search in Pixel System Intelligence Team
• [Google] Fact checking articles in Google news and web search
• [Google] Query understanding in web search
• [Yahoo] Salient terms extrations for Image articles

  During my internship as a researcher at Yahoo! Research Labs, I worked on extracting salient terms from image articles as part of a broader effort in content understanding. These extracted salient terms were subsequently utilized for retrieval and scoring during serving time, enhancing the relevance and accuracy of content-based operations.

  Following the successful completion of the internship, the position transitioned into a year-long academic collaboration between Yahoo! Research Labs and IIT Bombay. As part of this collaboration, I was awarded a research grant of INR 1,00,000 . You can learn more about this work from the presentation.
