Probability and Stochastic Processes
Malik Magdon-Ismail, a professor of computer science at Rensselaer Polytechnic Institute, is an expert in learning from data and decision-making in complex data systems. In his work, Magdon-Ismail mixes theory with validation through experiment or practice.
During the COVID-19 pandemic, he developed algorithms predicting aspects of the pandemic in small cities and school campuses. COVID War Room predicts the spread and severity of COVID-19 in small cities and counties through the United States and in select international locations. Building on the predictive power of the COVID War Room algorithms, Magdon-Ismail built COVID Back-to-School, a series of algorithms that make it possible to quantify the impacts of policy choices on the spread of COVID in a campus environment.
Other work include contributions to an intriguing project modeling stellar tidal streams from galactic collisions, mathematical models for optimal decision in a representative democracy, separating terrorist-like topological signatures embedded in benign networks, and understanding supercomputer failures using neuromorphic computing.

Machine Learning the Phenomenology of COVID-19 From Early Infection DynamicsarXiv
We present a robust data-driven machine learning analysis of the COVID-19 pandemic from its early infection dynamics, specifically infection counts over time. The goal is to extract actionable public health insights. These insights include the infectious force, the rate of a mild infection becoming serious, estimates for asymtomatic infections and predictions of new infections over time. We focus on USA data starting from the first confirmed infection on January 20 2020. Our methods reveal significant asymptomatic (hidden) infection, a lag of about 10 days, and we quantitatively confirm that the infectious force is strong with about a 0.14% transition from mild to serious infection. Our methods are efficient, robust and general, being agnostic to the specific virus and applicable to different populations or cohorts.
Nonlinear Dynamics from Incomplete NetworksAAAI
Chunheng Jiang, Jianxi Gao, Malik Magdon-Ismail
We study nonlinear dynamics on complex networks. Each vertex i has a state xi which evolves according to a networked dynamics to a steady-state x ∗i. We develop fundamental tools to learn the true steady-state of a small part of the network, without knowing the full network. A naive approach and the current state-of-the-art is to follow the dynamics of the observed partial network to local equilibrium. This dramatically fails to extract the true steady state. We use a mean-field approach to map the dynamics of the unseen part of the network to a single node, which allows us to recover accurate estimates of steady-state on as few as 5 observed vertices in domains ranging from ecology to social networks to gene regulation. Incomplete networks are the norm in practice, and we offer new ways to think about nonlinear dynamics when only sparse information is available.
