Aleatoric Uncertainty: When we have done any lab experiment, the values measured after multiple trials will never be the same. Even with all similar input values output measurements will differ Aleatoric uncertainty. The former is probably the more obvious one. Whenever you are taking multiple measurements under the same circumstances, it’s still quite unlikely to get every time the exact same result. Why is that? For several reasons: If you are using a sensor, every device itself has its accuracy, precision, resolution, etc. In case of a manual lab sample the used technique 如图 1. 所示，同一目标，靠近本车的 corner 点，其 Aleatoric Uncertainty 越小；距离越远，目标被遮挡的越严重，其 Aleatoric Uncertainty 越高。 1.2. 3D Object Detection by regressing location and orientation [3] 如图 2. 所示，网络结构比较简单，这里建模了三种 uncertainty: RPN bbox either epistemic or aleatoric in nature [2, 7, 3], where the former captures the uncertainty from the model while the latter captures uncertainty of the input data. The kind of uncertainty we wish to capture is aleatoric and cannot be reduced by collecting more data as opposed to epistemic uncertainty. Since the human pose is anthropomorphically Uncertainty is categorized into two types: epistemic (also known as systematic or reducible uncertainty) and aleatory (also known as statistical or irreducible uncertainty). Epistemic Uncertainty derives its name from the Greek word “επιστήμη” (episteme) which can be roughly translated as knowledge. Therefore, epistemic uncertainty is presumed to derive from the lack of knowledge of information regarding the phenomena that dictate how a system should behave, ultimately affecting Title: Aleatoric uncertainty estimation with test-time augmentation for medical image segmentation with convolutional neural networks. Authors: Guotai Wang, Wenqi Li, Michael Aertsen, Jan Deprest, Sebastien Ourselin, Tom Vercauteren. Download PDF Abstract: Despite the state-of-the-art performance for medical image segmentation, deep convolutional neural networks (CNNs) have rarely provided Aleatoric uncertainty is taken from the Latin word “alea,” which means dice, where the dice represent games of chance. Aleatoric uncertainty relates to probability-weighted outcomes, and the type of data you can plug into a spreadsheet. omit its analysis. Second, aleatoric uncertainty (from the Greek word alea, meaning “rolling a dice”) accounts for the stochasticity of the data. Aleatoric uncertainty describes the variance of the conditional distribution of our target variable given our features. This type of uncertainty arises due parameter ignorance, aleatoric uncertainty remains, for instance, due to sensor noise and motion noise. Aleatoric uncertainty cannot be explained away with more data; however, it can be formalized by a distribution over model outputs [5]. Aleatoric uncertainty can be further divided into two subtypes: homoscedastic and heteroscedastic. In the case of homoscedasticity, uncertainty is assumed to be While there can be many sources of uncertainty, in the context of modeling, it is convenient to catego-rize the character of uncertainties as either aleatory or epistemic. The word aleatory derives from the Latin alea , which means the rolling of dice. Thus, an aleatoric uncertainty is one that is presumed to be

A probability box (or p-box) is a characterization of an uncertain number consisting of both aleatoric and epistemic uncertainties that is often used in risk analysis or quantitative uncertainty ... Based on those translated images, the trained uncertainty-aware imitation learning policy would output both the predicted action and the data uncertainty motivated by the aleatoric loss function.
