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 Parametric Proper Orthogonal Decomposition Subspace Prediction
Melika Baghi, Xiao Liu, Kamran Paynabar
High-fidelity simulations such as computational fluid dynamics and finite element analysis are essential for modelling complex engineering systems but remain prohibitively expensiv…
Managing Shared Hospital Capacity for Medical Tourism: Patient Behavior and Hybrid Simulation
Melika Baghi, Hadi Mosadegh
Hospitals that serve medical tourists alongside local patients share beds, specialists, and appointment slots between two groups for whom waiting has different consequences. Operat…
