Variants of Tagged Sentential Decision Diagrams

no code implementations16 Nov 2023 Deyuan Zhong, Mingwei Zhang, Quanlong Guan, Liangda Fang, Zhaorong Lai, Yong Lai

The standard ones minimize the size of sentential decision diagrams (SDDs) while the zero-suppressed trimming rules have the same objective as the standard ones but for zero-suppressed sentential decision diagrams (ZSDDs).

VSRQ: Quantitative Assessment Method for Safety Risk of Vehicle Intelligent Connected System

no code implementations3 May 2023 Tian Zhang, Wenshan Guan, Hao Miao, Xiujie Huang, Zhiquan Liu, Chaonan Wang, Quanlong Guan, Liangda Fang, Zhifei Duan

We evaluate the model on OpenPilot and experimentally demonstrate the effectiveness of the VSRQ model in identifying the safety of vehicle intelligent connected systems.

A Mask-Based Adversarial Defense Scheme

no code implementations21 Apr 2022 Weizhen Xu, Chenyi Zhang, Fangzhen Zhao, Liangda Fang

Adversarial attacks hamper the functionality and accuracy of Deep Neural Networks (DNNs) by meddling with subtle perturbations to their inputs. In this work, we propose a new Mask-based Adversarial Defense scheme (MAD) for DNNs to mitigate the negative effect from adversarial attacks.

Knowledge Compilation in Multi-Agent Epistemic Logics

no code implementations27 Jun 2018 Liangda Fang, Kewen Wang, Zhe Wang, Ximing Wen

Epistemic logics are a primary formalism for multi-agent systems but major reasoning tasks in such epistemic logics are intractable, which impedes applications of multi-agent epistemic logics in automatic planning.
