New semi-random models challenge planted subgraph detection

Researchers have introduced semi-random models for planted subgraph detection, a departure from traditional purely random graph models. This new framework accounts for adversaries who may remove edges outside the planted subgraph, posing significant challenges to inference. The study establishes statistical limits, indicating that detection becomes information-theoretically impossible for subgraphs with very low density, while density above a certain threshold allows for robust detection. A computationally efficient algorithm is also proposed, offering rigorous statistical guarantees. AI
