Aditri Bhagirath - Persona Guided Personalization

Описание: Modern calls for pluralistic alignment argue that AI systems should adapt to individual users, yet most personalization approaches depend on explicit identity labels or predefined preference categories.
In this talk, I introduce SynthesizeMe, a method for inferring implicit user personas directly from interaction behavior. By synthesizing and validating reasoning about user preferences, inducing latent personas, and selectively grounding prompts in informative prior interactions, SynthesizeMe enables personalization without demographic data or manual labeling.
I’ll show how persona-guided prompting improves LLM-as-a-judge accuracy and how the same persona representations can power real product personalization: from ranking and generation to evaluation and feedback loops.

Intended audience: Engineers, researchers.

Aditri is a machine learning research engineer at Onton, an AI-powered e-commerce search engine. She earned her MS in Computer Science from Stanford University, where her research on persona creation was published at ACL. Previously, she spent four years at Meta, building community chat experiences across Messenger and Instagram. As an undergraduate, she studied Computer Science and Creative Writing at Carnegie Mellon University and conducted research in Tom Mitchell’s lab, focusing on predicting neural activation using LSTMs. Her other interests include consistent long-form video generation, acting, and writing.
