Decentralized Payment Clearing using Blockchain and Optimal Bidding
Hamed Amini, Maxim Bichuch, Zachary Feinstein
In this paper, we construct a decentralized clearing mechanism which endogenously and automatically provides a claims resolution procedure. This mechanism can be used to clear a ne…
Limit Theorems for Default Contagion and Systemic Risk
Hamed Amini, Zhongyuan Cao, Agnes Sulem
We consider a general tractable model for default contagion and systemic risk in a heterogeneous financial network, subject to an exogenous macroeconomic shock. We show that, under…
A Central Limit Theorem for Diffusion in Sparse Random Graphs
Hamed Amini, Erhan Bayraktar, Suman Chakraborty
We consider bootstrap percolation and diffusion in sparse random graphs with fixed degrees, constructed by configuration model. Every node has two states: it is either active or in…
Optimal Network Compression
Hamed Amini, Zachary Feinstein
This paper introduces a formulation of the optimal network compression problem for financial systems. This general formulation is presented for different levels of network compress…
Epidemic Spreading and Equilibrium Social Distancing in Heterogeneous Networks
Hamed Amini, Andreea Minca
We study a multi-type SIR epidemic process among a heterogeneous population that interacts through a network. When we base social contact on a random graph with given vertex degree…
Including Physics in Deep Learning -- An example from 4D seismic pressure saturation inversion
Jesper Sören Dramsch, Gustavo Corte, Hamed Amini +2
Geoscience data often have to rely on strong priors in the face of uncertainty. Additionally, we often try to detect or model anomalous sparse data that can appear as an outlier in…
