Conditional Validity for Adaptive Modality Acquisition: When the Policy Chooses Its Own Calibration Group
Melika Baghi
A multimodal system may begin inference while holding only some of its inputs and may acquire the rest at a cost. With adaptive acquisition, the policy determines which inputs are…
Pooling and Drift in Delayed Bandits
Melika Baghi
A system often has to act long before it learns whether the act worked: a recommender sees a click in seconds and a purchase in days. With actions and a delay of rounds, th…
Constrained Extreme Gradient Boosting for Adapting Reduced-Order Models
Melika Baghi, Xiao Liu, Kamran Paynabar
High-fidelity simulations, such as computational fluid dynamics and finite element analysis, are essential for modeling complex engineering systems but are often prohibitively expe…
Reducing Waiting Time for Medical Tourists Through Hybrid Agent-Based and Discrete-Event Simulation: A Hospital Case Study
Melika Baghi, Hadi Mosadegh
Medical tourists face a scheduling problem that differs from that of local patients. Treatment delays extend not just care delivery time, but also accommodation and travel costs. T…
