摘要翻译:
我们提出了新的具有连续时间反馈的Degroot型社会学习模型,以研究噪声信息源对社会网络中共识形成的影响。与标准的Degroot框架不同,噪声信息模型破坏了共识的形成。另一方面,噪声意见动态收敛于封装Agent意见之间相关性的均衡分布。有趣的是,这种平衡分布也是具有非零概率电流环的非平衡稳态(NESS)。因此,噪声信息源在很长一段时间内导致一个编码学习代理持续相关意见动态的NEST。我们的模型在社会学习的背景下提供了一个NESS的简单实现。本文还研究了Agent受共同噪声影响时的意见同步问题。

英文摘要:
We propose new Degroot-type social learning models with feedback in a continuous time, to investigate the effect of a noisy information source on consensus formation in a social network. Unlike the standard Degroot framework, noisy information models destroy consensus formation. On the other hand, the noisy opinion dynamics converge to the equilibrium distribution that encapsulates correlations among agents' opinions. Interestingly, such an equilibrium distribution is also a non-equilibrium steady state (NESS) with a non-zero probabilistic current loop. Thus, noisy information source leads to a NESS at long times that encodes persistent correlated opinion dynamics of learning agents. Our model provides a simple realization of NESS in the context of social learning. Other phenomena such as synchronization of opinions when agents are subject to a common noise are also studied.
