SERP Interference Network and Its Applications in Search AdvertisingJun 19, 2025
Leveraging censored observational data to construct bipartite interference networks.
Hi, I'm Purak Jain, an applied scientist.
These days I research and build multi-agent AI systems for AWS Frontier Agents with a small team of applied scientists / product engineers I lead.
Before I designed agents that allocate LLM compute, I built systems that allocate marketing spend. I spent 8 years in Amazon Growth, primarily on paid acquisition (search and social). My team built bidding algorithms, incrementality & elasticity measurement, and product recommender systems that optimized a couple of billion dollars in global ad spend across Google, Meta, YouTube, etc.
I write here about things I am learning.
