WebA Hierarchy of Near-Optimal Policies for Multi-stage Adaptive Optimization Dimitris Bertsimas ∗ Dan A. Iancu† Pablo A. Parrilo ‡ June 15, 2009 Abstract In this paper, we propose a new tractable framework for dealing with linear dynamical systems affected by uncertainty, applicable to multi-stage robust optimization and stochastic ... WebMar 5, 2016 · The adaptive distrbutaionally robust optimization framework caters for dynamic decision making, where decisions can adapt to the uncertain outcomes as they unfold in stages. For tractability considerations, we focus on a class of second-order conic (SOC) representable ambiguity set, though our results can easily be extended to more …

Webtimation and learning tasks, where a robust loss (say, ab-solute error) may be preferred over a non-robust loss (say, squared error) due to its reduced sensitivity to large errors. Researchers have developed various robust penalties with particular properties, many of which are summarized well in [3, 39]. In gradient descent or M-estimation [16 ... WebThis paper proposes a new methodology for building robust ensembles of time series forecasting models that utilizes Adaptive Robust Optimization (ARO) to construct a linear regression ensemble in which the models' weights can adapt over time. Accurate time series forecasting is critical for a wide range of problems with temporal data. Ensemble … rosebud hearing aids
A General and Adaptive Robust Loss Function
WebAbstract: Robust optimization has emerged in the operations research literature as a tractable and practical way to model uncertainty in optimization problems. Early approaches focused on relative worst-case objective functions, where the value of a solution is measured versus the best-possible solution over an uncertainty set of scenarios.
