摘要:

影响力最大化(Influence Maximization,IM)是经典的组合优化问题,可广泛应用于移动网络、社交计算与推荐系统中,其目标是选择少量用户,使在线社交网络中的影响传播范围最大化。由于具备潜在的商业与学术价值,众多研究者从不同角度开展IM问题研究。该问题的核心挑战在于IM本身的NP难特性,以及影响传播范围估计的#P难特性,传统解决算法可分为启发式算法与近似算法两类。但启发式算法无理论保证,近似算法的理论设计已接近极限,几乎无法进一步优化提升性能。随着人工智能的快速发展,基于机器学习(Machine Learning,ML)的技术在诸多领域取得显著成果。受此推动,近年来涌现出大量利用机器学习技术求解组合优化问题的新方法,这类方法求解速度快、对未知图的泛化能力强,为组合优化问题求解提供了全新方向。因此,本文摒弃基于迭代搜索的传统算法,梳理了基于机器学习的方法(尤其是深度强化学习)在求解社交网络中IM问题及其他变体问题上的最新进展,重点总结相关背景知识、基本原理、常用方法与应用研究,最后指出未来IM研究中亟待解决的挑战。

英文摘要:

Influence Maximization (IM) is a classical combinatorial optimization problem, which can be widely used in mobile networks, social computing, and recommendation systems. It aims at selecting a small number of users such that maximizing the influence spread across the online social network. Because of its potential commercial and academic value, there are a lot of researchers focusing on studying the IM problem from different perspectives. The main challenge comes from the NP-hardness of the IM problem and \#P-hardness of estimating the influence spread, thus traditional algorithms for overcoming them can be categorized into two classes: heuristic algorithms and approximation algorithms. However, there is no theoretical guarantee for heuristic algorithms, and the theoretical design is close to the limit. Therefore, it is almost impossible to further optimize and improve their performance. With the rapid development of artificial intelligence, the technology based on Machine Learning (ML) has achieved remarkable achievements in many fields. In view of this, in recent years, a number of new methods have emerged to solve combinatorial optimization problems by using ML-based techniques. These methods have the advantages of fast solving speed and strong generalization ability to unknown graphs, which provide a brand-new direction for solving combinatorial optimization problems. Therefore, we abandon the traditional algorithms based on iterative search and review the recent development of ML-based methods, especially Deep Reinforcement Learning, to solve the IM problem and other variants in social networks. We focus on summarizing the relevant background knowledge, basic principles, common methods, and applied research. Finally, the challenges that need to be solved urgently in future IM research are pointed out.
