Time Series Prediction using Deep Learning Methods in Healthcare

no code implementations30 Aug 2021 Mohammad Amin Morid, Olivia R. Liu Sheng, Joseph Dunbar

Secondly, these methods depend on feature engineering to capture the sequential nature of patient data, which may not adequately leverage the temporal patterns of the medical events and their dependencies.

Healthcare Cost Prediction: Leveraging Fine-grain Temporal Patterns

no code implementations14 Sep 2020 Mohammad Amin Morid, Olivia R. Liu Sheng, Kensaku Kawamoto, Travis Ault, Josette Dorius, Samir AbdelRahman

To prepare the data for modeling and prediction, the time series data of cost, visit and medical information were extracted in the form of fine-grain features (i. e., segmenting each time series into a sequence of consecutive windows and representing each window by various statistics such as sum).

PPMF: A Patient-based Predictive Modeling Framework for Early ICU Mortality Prediction

no code implementations25 Apr 2017 Mohammad Amin Morid, Olivia R. Liu Sheng, Samir AbdelRahman

The first component captures dynamic changes of patients status in the ICU using their time series data (e. g., vital signs and laboratory tests).
