An Uncertainty Estimation Framework for Risk Assessment in Deep Learning-based Atrial Fibrillation Classification

no code implementations30 Oct 2020 James Belen, Sajad Mousavi, Alireza Shamsoshoara, Fatemeh Afghah

The uncertainty is estimated by conducting multiple passes of the input through the network to build a distribution; the mean of the standard deviations is reported as the network's uncertainty.
