Finding Influencers in Complex Networks: An Effective Deep Reinforcement Learning Approach

no code implementations9 Sep 2023 Changan Liu, Changjun Fan, Zhongzhi Zhang

Maximizing influences in complex networks is a practically important but computationally challenging task for social network analysis, due to its NP- hard nature.

Minimizing Polarization and Disagreement in Social Networks via Link Recommendation

no code implementations NeurIPS 2021 Liwang Zhu, Qi Bao, Zhongzhi Zhang

Individual's opinions are fundamentally shaped and evolved by their interactions with other people, and social phenomena such as disagreement and polarization are now tightly woven into daily life.

Role Similarity Metric Based on Spanning Rooted Forest

1 code implementation15 Oct 2021 Qi Bao, Zhongzhi Zhang, Haibin Kan

We prove that \textsf{ForestSim} is an admissible role similarity metric and devise the corresponding top-k similarity search algorithm, namely \textsf{ForestSimSearch}, which is able to process a top-k query in $O(k)$ time once the precomputation is finished.

Fast Evaluation for Relevant Quantities of Opinion Dynamics

1 code implementation20 Jan 2021 Wanyue Xu, Qi Bao, Zhongzhi Zhang

One of the main subjects in the field of social networks is to quantify conflict, disagreement, controversy, and polarization, and some quantitative indicators have been developed to quantify these concepts.
