Improving Recurrent Neural Network Responsiveness to Acute Clinical Events

no code implementations28 Jul 2020 David Ledbetter, Eugene Laksana, Melissa Aczon, Randall Wetzel

This work presents input data perseveration as a method of training and deploying an RNN model to make its predictions more responsive to newly acquired information: input data is replicated during training and deployment.

Interpreting a Recurrent Neural Network's Predictions of ICU Mortality Risk

no code implementations23 May 2019 Long V. Ho, Melissa D. Aczon, David Ledbetter, Randall Wetzel

Deep learning has demonstrated success in many applications; however, their use in healthcare has been limited due to the lack of transparency into how they generate predictions.

The Impact of Extraneous Variables on the Performance of Recurrent Neural Network Models in Clinical Tasks

no code implementations1 Apr 2019 Eugene Laksana, Melissa Aczon, Long Ho, Cameron Carlin, David Ledbetter, Randall Wetzel

Electronic Medical Records (EMR) are a rich source of patient information, including measurements reflecting physiologic signs and administered therapies.

Predicting Individual Responses to Vasoactive Medications in Children with Septic Shock

no code implementations15 Jan 2019 Nicole Fronda, Jessica Asencio, Cameron Carlin, David Ledbetter, Melissa Aczon, Randall Wetzel, Barry Markovitz

Conclusion: This initial attempt in pediatric critical care to predict individual physiologic responses to vasoactive dose changes in children with septic shock demonstrated an RNN model showed some improvement over a linear model.

Predicting Individual Physiologically Acceptable States for Discharge from a Pediatric Intensive Care Unit

no code implementations18 Dec 2017 Cameron Carlin, Long Van Ho, David Ledbetter, Melissa Aczon, Randall Wetzel

Design: The means of each patient's hr, sbp and dbp measurements between their medical and physical discharge from the ICU were computed as a proxy for their physiologically acceptable state space (PASS) for successful ICU discharge.

Prediction of Kidney Function from Biopsy Images Using Convolutional Neural Networks

no code implementations6 Feb 2017 David Ledbetter, Long Ho, Kevin V Lemley

A Convolutional Neural Network was used to predict kidney function in patients with chronic kidney disease from high-resolution digital pathology scans of their kidney biopsies.
