Learning Algorithms for Minimizing Queue Length Regret

چکیده
We consider a system consisting of single transmitter/receiver pair and N channels over which they may communicate. Packets randomly arrive to the transmitter’s queue wait be successfully sent receiver. The transmitter attempt frame transmission on one channel at time, where each includes packet if is in queue. For channel, an attempted successful with unknown probability. objective quickly identify best minimize number packets T time slots. To analyze performance, we introduce length regret, expected difference between total learning policy controller that knows rates, priori. One approach designing would apply algorithms from literature solve closely-related stochastic multi-armed bandit problem. These policies focus maximizing transmissions time. However, show these methods have $\Omega (\log {{T}})$ regret. On other hand, there exists set queue-length based can obtain order optimal ${O}(1)$ use our theoretical analysis devise heuristic are shown perform well simulation.

Efficient Algorithms for k-Regret Minimizing Sets
A regret minimizing set Q is a small size representation of a much larger database P so that user queries executed on Q return answers whose scores are not much worse than those on the full dataset. In particular, a k-regret minimizing set has the property that the regret ratio between the score of the top-1 item in Q and the score of the top-k item in P is minimized, where the score of an item...
متن کاملMore Efficient Internal-Regret-Minimizing Algorithms
Standard no-internal-regret (NIR) algorithms compute a fixed point of a matrix, and hence typically require O(n) run time per round of learning, where n is the dimensionality of the matrix. The main contribution of this paper is a novel NIR algorithm, which is a simple and straightforward variant of a standard NIR algorithm. However, rather than compute a fixed point every round, our algorithm ...
متن کاملk-Regret Minimizing Set: Hardness and Efficient Algorithms
We study the k-regret minimizing query (k-RMS), which is a useful operator of supporting multi-criteria decision-making. Given two integers k and r, a k-RMS returns r tuples from the database which minimize the k-regret ratio, defined as one minus the worst ratio between the k-th maximum utility score among all tuples in the database and the maximum utility score of the r tuples returned. A sol...

We study the problem of computing and learning non-anonymous reserve prices to maximize revenue. We first define the MAXIMIZING MULTIPLE RESERVES (MMR) problem in single-parameter matroid environments, where the input is m valuation profiles v1, . . . ,vm, indexed by the same n bidders, and the goal is to compute the vector r of (non-anonymous) reserve prices that maximizes the total revenue ob...
