Lifted Algorithms for Symmetric Weighted First-Order Model Sampling

no code implementations17 Aug 2023 Yuanhong Wang, Juhua Pu, Yuyi Wang, Ondřej Kuželka

Specifically, we prove the domain-liftability under sampling for the two-variables fragment of first-order logic with counting quantifiers in this paper, by devising an efficient sampling algorithm for this fragment that runs in time polynomial in the domain size.

On Exact Sampling in the Two-Variable Fragment of First-Order Logic

1 code implementation6 Feb 2023 Yuanhong Wang, Juhua Pu, Yuyi Wang, Ondřej Kuželka

In this paper, we study the sampling problem for first-order logic proposed recently by Wang et al. -- how to efficiently sample a model of a given first-order sentence on a finite domain?

Complex Handwriting Trajectory Recovery: Evaluation Metrics and Algorithm

1 code implementation28 Oct 2022 Zhounan Chen, Daihui Yang, Jinglin Liang, Xinwu Liu, Yuyi Wang, Zhenghua Peng, Shuangping Huang
