Inverse Ising inference from high-temperature re-weighting of observations

no code implementations10 Sep 2019 Junghyo Jo, Danh-Tai Hoang, Vipul Periwal

Maximum Likelihood Estimation (MLE) is the bread and butter of system inference for stochastic systems.

Causality inference in stochastic systems from neurons to currencies: Profiting from small sample size

2 code implementations18 May 2017 Danh-Tai Hoang, Juyong Song, Vipul Periwal, Junghyo Jo

We introduce a data-driven statistical physics approach to model inference based on minimizing a free energy of data and show superior model recovery for small sample sizes.

A Local Counter-Regulatory Motif Modulates the Global Phase of Hormonal Oscillations

no code implementations19 Jul 2016 Dong-Ho Park, Taegeun Song, Danh-Tai Hoang, Jin Xu, Junghyo Jo

By testing all possible motifs governing the interactions of these three cell types, we found that a unique set of positive/negative intra-islet interactions between different islet cell types functions not only to reduce the superficially wasteful zero-sum action of glucagon and insulin but also to enhance/suppress the synchronization of hormone secretions between islets under high/normal glucose conditions.

Minimal Perceptrons for Memorizing Complex Patterns

no code implementations12 Dec 2015 Marissa Pastor, Juyong Song, Danh-Tai Hoang, Junghyo Jo

We developed a new complexity measure of binary patterns, and estimated the minimal network size for memorizing them as a function of their complexity.
