The Best Time for an Update: Risk-Sensitive Minimization of Age-Based Metrics

no code implementations3 Jan 2024 Wanja de Sombre, Andrea Ortiz, Frank Aurzada, Anja Klein

The second strategy uses an enhanced Q-learning approach and balances the age-based metric, the transmission energy and the frequency of risky states without requiring knowledge about the system.

Context-Aware Hierarchical Online Learning for Performance Maximization in Mobile Crowdsourcing

no code implementations10 May 2017 Sabrina Klos, Cem Tekin, Mihaela van der Schaar, Anja Klein

In our algorithm, a local controller (LC) in the mobile device of a worker regularly observes the worker's context, her/his decisions to accept or decline tasks and the quality in completing tasks.

Context-Aware Proactive Content Caching with Service Differentiation in Wireless Networks

no code implementations14 Jun 2016 Sabrina Müller, Onur Atan, Mihaela van der Schaar, Anja Klein

We derive a sublinear regret bound, which characterizes the learning speed and proves that our algorithm converges to the optimal cache content placement strategy in terms of maximizing the number of cache hits.
