Title
Interpreting a recurrent neural network’s predictions of ICU mortality risk
Abstract
•Introduce Learned Binary Masks (LBM) to interpret an RNN’s ICU mortality predictions.•Attribute individual RNN predictions to their input features using LBM & KernelSHAP.•Aggregate attributions from KernelSHAP and LBM to interpret the RNN at various scales.•Introduce a patient data representation that facilitates use of LBM and KernelSHAP.
