Structural Causal Models for Extremes: an Approach Based on Exponent Measures
Shuyang Bai, Fei Fang, Tiandong Wang
We introduce a new formulation of structural causal models for extremes, called the extremal structural causal model (eSCM). Unlike conventional structural causal models, where ran…
Spatial-Temporal Feedback Diffusion Guidance for Controlled Traffic Imputation
Xiaowei Mao, Huihu Ding, Yan Lin +6
Imputing missing values in spatial-temporal traffic data is essential for intelligent transportation systems. Among advanced imputation methods, score-based diffusion models have d…
Design-Based Weighted Regression Estimators for Average and Conditional Spillover Effects
Fei Fang, Laura Forastiere
When individuals engage in social or physical interactions, a unit's outcome may depend on the treatments received by others. In such interference environments, we provide a unifie…
Edge-based reputation promotes cooperation in simplicial complexes
Chunpeng Du, Fei Fang, Alfonso de Miguel-Arribas +4
Understanding how cooperation emerges and persists is a central challenge in the evolutionary dynamics of social and biological systems. Most prior studies have examined cooperatio…
Inward and Outward Spillover Effects of One Unit's Treatment on Network Neighbors under Partial Interference
Fei Fang, Edoardo M Airoldi, Laura Forastiere
In settings where interference is present, direct effects are commonly defined as the average effect of a unit's treatment on their own outcome while fixing the treatment status or…
