A Two-Stage Operating Room Allocation Framework for Reducing Surgical Waiting Lists in Public Hospitals
Jhoan Báez, Juan Hoyos, Víctor Riquelme +2
Operating-room allocation is a major challenge for public hospitals with limited surgical capacity and large elective waiting lists. This work proposes a two-stage operating-room a…
Forecasting Seasonal Peaks of Pediatric Respiratory Infections Using an Alert-Based Model Combining SIR Dynamics and Historical Trends in Santiago, Chile
Gloria HenrÃquez, Jhoan Báez, VÃctor Riquelme +3
Acute respiratory infections (ARI) are a major cause of pediatric hospitalization in Chile, producing marked winter increases in demand that challenge hospital planning. This study…
Koopman Kalman Filter (KKF): An asymptotically optimal nonlinear filtering algorithm with error bounds and its application to parameter estimation
Diego OlguÃn, Axel Osses, Héctor RamÃrez
In this article, we propose a new filtering algorithm based in the Koopman operator, showing that a nonlinear filtering problem can be seen as an equivalent problem where the dynam…
Improved error bounds for Koopman operator and reconstructed trajectories approximations with kernel-based methods
Diego OlguÃn, Axel Osses, Héctor RamÃrez
In this article, we propose a new error bound for Koopman operator approximation using Kernel Extended Dynamic Mode Decomposition. The new estimate is , with a constan…
