SimGym: A Framework for A/B Test Simulation in E-Commerce with Traffic-Grounded VLM Agents
Han Li, Vibhor Malik, Zahra Zanjani Foumani +17
A/B testing remains the gold standard for evaluating modifications to e-commerce storefronts, yet it diverts traffic, requires weeks to reach statistical significance, and risks de…
SimPersona: Learning Discrete Buyer Personas from Raw Clickstreams for Grounded E-Commerce Agents
Zahra Zanjani Foumani, Alberto Castelo, Shuang Xie +3
LLM-based web agents can navigate live storefronts, yet they often collapse to a single "average buyer" policy, failing to capture the heterogeneous and distributional nature of re…
SimGym: Traffic-Grounded Browser Agents for Offline A/B Testing in E-Commerce
Alberto Castelo, Zahra Zanjani Foumani, Ailin Fan +17
A/B testing remains the gold standard for evaluating e-commerce UI changes, yet it diverts traffic, takes weeks to reach significance, and risks harming user experience. We introdu…
Constrained multi-fidelity Bayesian optimization with automatic stop condition
Zahra Zanjani Foumani, Ramin Bostanabad
Bayesian optimization (BO) is increasingly employed in critical applications to find the optimal design with minimal cost. While BO is known for its sample efficiency, relying sole…
A preliminary data fusion study to assess the feasibility of Foundation Process-Property Models in Laser Powder Bed Fusion
Oriol Vendrell-Gallart, Nima Negarandeh, Zahra Zanjani Foumani +3
Foundation models are at the forefront of an increasing number of critical applications. In regards to technologies such as additive manufacturing (AM), these models have the poten…
