Parallel ensemble methods for causal direction inference

no code implementations5 Jun 2020 Yulai Zhang, Jiachen Wang, Gang Cen, Guiming Luo

Inferring the causal direction between two variables from their observation data is one of the most fundamental and challenging topics in data science.

Attacker and Defender Counting Approach for Abstract Argumentation

no code implementations13 Jun 2015 Fuan Pu, Jian Luo, Yulai Zhang, Guiming Luo

In this paper, we propose a counting approach for a more fine-gained assessment to arguments by counting the number of their respective attackers and defenders based on argument graph and argument game.

Argument Ranking with Categoriser Function

no code implementations16 Jun 2014 Fuan Pu, Jian Luo, Yulai Zhang, Guiming Luo

Recently, ranking-based semantics is proposed to rank-order arguments from the most acceptable to the weakest one(s), which provides a graded assessment to arguments.
