Mixing Predictions for Online Metric Algorithms

ICML 2023poster

A major technique in learning-augmented online algorithms is combining multiple algorithms or predictors. Since the performance of each predictor may vary over time, it is desirable to use not the single best predictor as a benchmark, but rather a dynamic combination which follows different predicto…

Learning-Augmented Dynamic Power Management with Multiple States via New Ski Rental Bounds

NeurIPS 2021poster

We study the online problem of minimizing power consumption in systems with multiple power-saving states. During idle periods of unknown lengths, an algorithm has to choose between power-saving states of different energy consumption and wake-up costs. We develop a learning-augmented online algorithm…

Online metric algorithms with untrusted predictions

ICML 2020poster

Machine-learned predictors, although achieving very good results for inputs resembling training data, cannot possibly provide perfect predictions in all situations. Still, decision-making systems that are based on such predictors need not only to benefit from good predictions but also to achieve a d…
