引用网络的双向共因子分析

研究问题
引用网络受论文发表时间约束、部分邻接矩阵结构性缺失时,能否识别分别描述发出引用和接收引用的潜在空间?
方法与思路
作者建立下三角缺失的非对称邻接矩阵共因子模型,将估计转化为矩阵补全,并设计适应大规模内存限制的实现。
材料陈述的贡献
摘要称模型在时间约束下仍可识别,模拟展示潜在结构恢复能力,并用大规模统计论文网络提取具有可解释性的主题因子。
阅读关注点
应核对共因子识别的限制、时间造成的结构性缺失如何处理,以及矩阵补全的误差条件;检查主题解释和基准比较方式。
阅读边界
这是 arXiv 预印本,同行评审及期刊接收未经核实;摘要未给出完整识别条件,其主题模型覆盖程度和解释质量尚不能独立判断。

原文摘要

One compelling use of citation networks is to characterize papers by their relationships to the surrounding literature. We propose a method to characterize papers by embedding them into two distinct "co-factor" spaces: one describing how papers send citations, and the other describing how papers receive citations. This approach presents several challenges. First, older documents cannot cite newer documents, and thus it is not clear that co-factors are even identifiable. We resolve this challenge by developing a co-factor model for asymmetric adjacency matrices with missing lower triangles and showing that identification is possible. We then frame estimation as a matrix completion problem and develop a specialized implementation of matrix completion because prior implementations are memory bound in our setting. Simulations show that our estimator has promising finite sample properties, and that naive approaches fail to recover latent co-factor structure. We leverage our estimator to investigate 255,780 papers published in statistics journals from 1898 to 2024, resulting in the most comprehensive topic model of the statistics literature to date. We find interpretable co-factors corresponding to many statistical subfields, including time series, variable selection, spatial methods, graphical models, GLM(M)s, causal inference, multiple testing, quantile regression, semiparametrics, dimension reduction, and several more.
