Inference of the kinetic Ising model with heterogeneous missing data

C Campajola, F Lillo, D Tantari - Physical Review E, 2019 - APS
We consider the problem of inferring a causality structure from multiple binary time series by
using the kinetic Ising model in datasets where a fraction of observations is missing. Inspired …

Reverse-engineering biological networks from large data sets

JL Natale, D Hofmann, DG Hernández… - arXiv preprint arXiv …, 2017 - arxiv.org
Much of contemporary systems biology owes its success to the abstraction of a network, the
idea that diverse kinds of molecular, cellular, and organismal species and interactions can …
