WebBeyond Adaptive Submodularity: Approximation Guarantees of Greedy Policy with Adaptive Submodularity Ratio Kaito Fujii1 Shinsaku Sakaue2 Abstract We propose a new concept named adaptive sub-modularity ratio to study the greedy policy for sequential decision making. While the greedy policy is known to perform well for a wide variety Webized greedy algorithm that achieves a 5:83 approximation and runs in O(nlogn) time, i.e., at least a factor nfaster than other state-of-the-art algorithms. The robustness of our approach allows us to further transfer it to a stochastic version of the problem. There, we obtain a 9-approximation to the best adaptive policy, which

WebJul 2, 2014 · In this paper, we address the problem of learning the geometry of a non-linear manifold in the ambient Euclidean space into which the manifold is embedded. We propose a bottom-up approach to manifold approximation using tangent planes where the number of planes is adaptive to manifold curvature. Also, we exploit the local linearity of the … WebWe give a simple, randomized greedy algorithm for the maximum satisfiability problem (MAX SAT) that obtains a $\\frac{3}{4}$-approximation in expectation. In contrast to previously known $\\frac{3}{4}$-approximation algorithms, our algorithm does not use flows or linear programming. Hence we provide a positive answer to a question posed by …
