Cost curve-based aleatoric uncertainty estimation. (a) An ideal curve, characterised by a single minimum with zero cost and all other values being one. (b) A more realistic curve with multiple minima, but a reliably identifiable global minimum. The above behaviours depend on 2 notable uncertainties (aleatoric and epistemic) and were introduce to computer vision task by Kendall, NIPS 2017. Aleatoric uncertainty. Uncertainty formalized as a probability distribution over model output. This is uncertainty in the input data it has observed. Aleatoric uncertainty estimation with test-time augmentation. The uncertainty is estimated by measuring how diverse the predictions for a given image are. Both the variance and entropy of the distribution p(YX) can be used to estimate uncertainty. However, variance is not sufficiently representative in the context of multi-modal distributions. Structured Aleatoric Uncertainty in Human Pose Estimation Nitesh B. Gundavarapu1 Divyansh Srivastava1 Rahul Mitra1 Abhishek Sharma2 Arjun Jain1 1Indian Institute of Technology, Bombay 2Axogyan AI, Bangalore Abstract Human pose estimation from monocular images exhibits an inherent uncertainty through self-occlusions and inter- Epistemic uncertainty quantification methods. In literature, the most common methods of modeling epistemic uncertainty are the following. Bayesian probability is a method that appoints a frequency or probability of an event, based on an educated guess or a personal belief.; Evidence theory, also known and as Dempster-Shafer theory or theory of belief functions. Despite the state-of-the-art performance for medical image segmentation, deep convolutional neural networks (CNNs) have rarely provided uncertainty estimations regarding their segmentation outputs, e.g., model (epistemic) and image-based (aleatoric) uncertainties. In this work, we analyze these different types of uncertainties for CNN-based 2D and 3D medical image segmentation tasks. We ... Aleatoric uncertainty estimation with test-time augmentation for medical image segmentation with convolutional neural networks. 07/19/2018 ∙ by Guotai Wang, et al. ∙ King's College London ∙ 12 ∙ share Despite the state-of-the-art performance for medical image segmentation, deep convolutional neural networks (CNNs) have ... Age-related macular degeneration (AMD) is one of the leading causes of permanent vision loss in people aged over 60 years. Accurate segmentation of biomarkers such as drusen that points to the early stages of AMD is crucial in preventing further vision impairment. However, segmenting drusen is extremely challenging due to their varied sizes and appearances, low contrast and noise resemblance ... 3 Test-time Data Augmentation for Aleatoric Uncertainty Estimation We aim to test whether it is possible to use data augmentation techniques as an efficient and effective means to explore the locality of the example given in Figure 1 with a sweeping capacity greater than 1.
