Quantifying uncertainty of machine learning methods for loss given default

open access: yesFrontiers in Applied Mathematics and Statistics, 2022
Machine learning has increasingly found its way into the credit risk literature. When applied to forecasting credit risk parameters, the approaches have been found to outperform standard statistical models. The quantification of prediction uncertainty is

Epistemic and aleatoric uncertainties reduction with rotation variation for medical image segmentation with ConvNets

open access: yesSN Applied Sciences, 2022
The deep convolutional neural network (ConvNet) achieves significant segmentation performance on medical images of various modalities. However, the isolated errors in a large testing set with various tumor conditions are not acceptable in clinical ...

Recalibration of Aleatoric and EpistemicRegression Uncertainty in Medical Imaging

open access: yesMachine Learning for Biomedical Imaging, 2021
The consideration of predictive uncertainty in medical imaging with deep learning is of utmost importance. We apply estimation of both aleatoric and epistemic uncertainty by variational Bayesian inference with Monte Carlo dropout to regression tasks and show that predictive uncertainty is systematically underestimated.

Aleatoric and epistemic uncertainty in machine learning: an introduction to concepts and methods [PDF]

open access: yesMachine Learning, 2021
AbstractThe notion of uncertainty is of major importance in machine learning and constitutes a key element of machine learning methodology. In line with the statistical tradition, uncertainty has long been perceived as almost synonymous with standard probability and probabilistic predictions.

Aleatoric Uncertainty for Errors-in-Variables Models in Deep Regression

open access: yesNeural Processing Letters, 2022
AbstractA Bayesian treatment of deep learning allows for the computation of uncertainties associated with the predictions of deep neural networks. We show how the concept of Errors-in-Variables can be used in Bayesian deep regression to also account for the uncertainty associated with the input of the employed neural network.

How to measure uncertainty in uncertainty sampling for active learning [PDF]

open access: yes, 2022
Various strategies for active learning have been proposed in the machine learning literature. In uncertainty sampling, which is among the most popular approaches, the active learner sequentially queries the label of those instances for which its current ...
