Federated learning model for predicting major postoperative complications

no code implementations9 Apr 2024 Yonggi Park, Yuanfang Ren, Benjamin Shickel, Ziyuan Guan, Ayush Patela, Yingbo Ma, Zhenhong Hu, Tyler J. Loftus, Parisa Rashidi, Tezcan Ozrazgat-Baslanti, Azra Bihorac

Federated learning models achieved comparable AUROC performance to central learning models, except for prolonged ICU stay, where the performance of federated learning models was slightly higher than central learning models at UFH GNV center, but slightly lower at UFH JAX center.

Opening the Blackbox: Accelerating Neural Differential Equations by Regularizing Internal Solver Heuristics

3 code implementations9 May 2021 Avik Pal, Yingbo Ma, Viral Shah, Christopher Rackauckas

While we can control the computational cost by choosing the number of layers in standard architectures, in NDEs the number of neural network evaluations for a forward pass can depend on the number of steps of the adaptive ODE solver.

Stiff Neural Ordinary Differential Equations

1 code implementation29 Mar 2021 Suyong Kim, Weiqi Ji, Sili Deng, Yingbo Ma, Christopher Rackauckas

We first show the challenges of learning neural ODE in the classical stiff ODE systems of Robertson's problem and propose techniques to mitigate the challenges associated with scale separations in stiff systems.

Accelerating Simulation of Stiff Nonlinear Systems using Continuous-Time Echo State Networks

no code implementations7 Oct 2020 Ranjan Anantharaman, Yingbo Ma, Shashi Gowda, Chris Laughman, Viral Shah, Alan Edelman, Chris Rackauckas

Modern design, control, and optimization often requires simulation of highly nonlinear models, leading to prohibitive computational costs.

Universal Differential Equations for Scientific Machine Learning

7 code implementations13 Jan 2020 Christopher Rackauckas, Yingbo Ma, Julius Martensen, Collin Warner, Kirill Zubov, Rohit Supekar, Dominic Skinner, Ali Ramadhan, Alan Edelman

In the context of science, the well-known adage "a picture is worth a thousand words" might well be "a model is worth a thousand datasets."
