Statistical inference of a ranked community in a directed graph
Dmitriy Kunisky, Daniel A. Spielman, Alexander S. Wein +1
We study the problem of detecting or recovering a planted ranked subgraph from a directed graph, an analog for directed graphs of the well-studied planted dense subgraph model. We…
Tensor cumulants for statistical inference on invariant distributions
Dmitriy Kunisky, Cristopher Moore, Alexander S. Wein
Many problems in high-dimensional statistics appear to have a statistical-computational gap: a range of values of the signal-to-noise ratio where inference is information-theoretic…
Information-Theoretic Thresholds for Planted Dense Cycles
Cheng Mao, Alexander S. Wein, Shenduo Zhang
We study a random graph model for small-world networks which are ubiquitous in social and biological sciences. In this model, a dense cycle of expected bandwidth , representin…
