Social System Inference from Noisy Observations

Yanbing Mao, Naira Hovakimyan, Tarek Abdelzaher, Evangelos Theodorou

摘要:

本文研究了从公众意见演化的单一轨迹进行社会系统推理,其中观测噪声导致样本对时间和坐标的统计依赖。我们首先提出了一个网络社会系统,包括个人在社会网络和一组信息源在网络层,其意见动态明确考虑确认偏见,新颖性偏见和过程噪声。基于所提出的社会模型,然后我们研究了最小二乘自回归模型估计的样本复杂性,它控制着足够的观测数量,以使所识别的模型达到规定的准确度和置信度。建立在确定的社会模型,我们然后研究社会推理,特别关注的加权网络拓扑结构,潜意识的偏见和模型参数的确认偏差和新颖性偏差。最后,通过美国参议院议员意识形态数据验证了理论结果和所提出的社会模型及推理算法的有效性。

英文摘要:

This paper studies social system inference from a single trajectory of public evolving opinions, wherein observation noise leads to the statistical dependence of samples on time and coordinates. We first propose a cyber-social system that comprises individuals in a social network and a set of information sources in a cyber layer, whose opinion dynamics explicitly takes confirmation bias, novelty bias and process noise into account. Based on the proposed social model, we then study the sample complexity of least-square auto-regressive model estimation, which governs the number of observations that are sufficient for the identified model to achieve the prescribed levels of accuracy and confidence. Building on the identified social model, we then investigate social inference, with particular focus on the weighted network topology, the subconscious bias and the model parameters of confirmation bias and novelty bias. Finally, the theoretical results and the effectiveness of the proposed social model and inference algorithm are validated by the US Senate Member Ideology data.
