Nettetwe can call it optimal. This extremely strong type of optimality is called instance optimality, and it is the subject of this lecture. Remark 1.2 (Worst-Case Analysis) In the … NettetAbstract. In probably approximately correct (PAC) reinforcement learning (RL), an agent is required to identify an ϵ ϵ -optimal policy with probability 1−δ 1 − δ. While minimax optimal algorithms exist for this problem, its instance-dependent complexity remains elusive in episodic Markov decision processes (MDPs). In this paper, we ... feed line loss https://theresalesolution.com

NettetAlthough we do not know the optimal solution for the generated large instances, obviously we can certify the optimality of the heuristic solution in case a solution with an objective function value equal to zero is identified. We can see that, as the size of the instance increases, the number of zero-solutions improves. NettetInstance optimality.

They proposed an algo-rithm also based on the lower bound optimization problem to achieve instance-optimality, but their algorithm is deter-ministic and cannot be robust to an adversary. Instance-optimality was also considered in other related problems lately such as linear contextual bandits (Hao et al.,2024;

Nettet1. jun. 2024 · This paper takes a principled approach, yielding a mechanism that is instance-optimal in a strong sense. In addition to its theoretical optimality, the mechanism is also simple and practical, and adapts to a variety of data characteristics without the need of parameter tuning.

Nettet1. jun. 2024 · Instance complexity is a measure of goodness of an algorithm in which the performance of one algorithm is compared to others per input. This is in sharp contrast to worst-case and average-case complexity measures, where the performance is compared either on the worst input or on an average one, respectively.
