Individual predictions matter: Assessing the effect of data ordering in training fine-tuned CNNs for medical imaging

1 code implementation8 Dec 2019 John R. Zech, Jessica Zosa Forde, Michael L. Littman

Averaging predictions from 10 models reduced variability by nearly 70% (mean coefficient of variation from 0. 543 to 0. 169, t-test 15. 96, p-value < 0. 0001).

Deep Learning Predicts Hip Fracture using Confounding Patient and Healthcare Variables

no code implementations8 Nov 2018 Marcus A. Badgeley, John R. Zech, Luke Oakden-Rayner, Benjamin S. Glicksberg, Manway Liu, William Gale, Michael V. McConnell, Beth Percha, Thomas M. Snyder, Joel T. Dudley

In this study, we trained deep learning models on 17, 587 radiographs to classify fracture, five patient traits, and 14 hospital process variables.

Confounding variables can degrade generalization performance of radiological deep learning models

no code implementations2 Jul 2018 John R. Zech, Marcus A. Badgeley, Manway Liu, Anthony B. Costa, Joseph J. Titano, Eric K. Oermann

Early results in using convolutional neural networks (CNNs) on x-rays to diagnose disease have been promising, but it has not yet been shown that models trained on x-rays from one hospital or one group of hospitals will work equally well at different hospitals.
