In this session, the PyMC Labs team explores how Large Language Models (LLMs) and their Semantic Similarity Rating (SSR) methodology can replicate human purchase intent with up to 90% of human test-retest reliability. Building on this research, we’ll introduce the Synthetic Consumers Platform—a breakthrough in simulated customer insights that generates reliable, human-like survey data at scale and in a fraction of the time. You’ll learn how synthetic consumers and SSR can transform customer research by enabling faster iteration and significantly reducing costs, and how an AI-driven insights platform accelerates testing, validation, and decision-making in marketing research and creative testing.

🎙️ Speaker: Dr. Ulf Aslak Lai\| ⏰ Time: 16:00 UTC / 9:00 am PT / 12:00 pm ET / 6:00 pm Berlin

Marketing Mix Modeling is a mathematical approach to estimating the effect of marketing on sales. It has become increasingly popular in recent years due to the increasing difficulty of traditional cookie-tracking for marketing attribution. In opposition to tracking-based methods, MMM models the effect of marketing using aggregated data like daily or weekly impressions and sales.

In this session, Dr. Ulf Aslak Lai joins Dr. Thomas Wiecki for a conversation about open-source software for Marketing Mix Modeling (MMM). Ulf will share some background on how he was introduced to the problem and eventually made his way into the community of PyMC-Marketing developers, then present a comprehensive overview of PyMC-Marketing focusing on recent innovations like experiment integration and time-varying coefficients. Thomas and Ulf will discuss the advantage of a Bayesian approach to MMM, and the challenges inherent to the modeling problem, and share some predictions for the future.
