AI, Statistics and Data Science in Practice Webinar: Tim Hesterberg

Tuesday, October 14, 2025 - 12:00pm to 1:30pm

Overview

The AI, Statistics & Data Science in Practice Series during Fall 2025 will focus on the critical role of experimentation in the development and refinement of artificial intelligence (AI) systems: "Incorporating principles of design of experiments and randomization ensures that AI models are trained on reliable, unbiased data, leading to more generalizable and interpretable results. By planning data collection with experimental design and randomization, researchers can minimize bias from uncontrolled variables and improve the statistical validity of their conclusions, whether the models are inferential or predictive. However, in many real-world scenarios, fully controlled experiments may not be feasible. When working with observational data, researchers can employ quasi-experimental techniques to approximate the benefits of randomized trials. These methods help isolate the effects of key variables and adjust for potential confounders, improving the robustness of AI-driven insights. By integrating structured experimentation and causal inference methodologies, AI developers can enhance the reliability and applicability of their models in practice.
