Systemic Risk Models for Disjoint and Overlapping Groups with Equilibrium Strategies

no code implementations1 Feb 2022 Yichen Feng, Jean-Pierre Fouque, Ruimeng Hu, Tomoyuki Ichiba

We introduce the concept of Nash equilibrium for these new models, and analyze the optimal solution under Gaussian distribution of the risk factor.

Meta-Graph Based HIN Spectral Embedding: Methods, Analyses, and Insights

no code implementations29 Sep 2019 Carl Yang, Yichen Feng, Pan Li, Yu Shi, Jiawei Han

In this work, we propose to study the utility of different meta-graphs, as well as how to simultaneously leverage multiple meta-graphs for HIN embedding in an unsupervised manner.
