Deep residual networkSpatiotemporal dataFeature enhancementInterval prediction is an efficient approach for quantifying the uncertainties of future flow. In this paper, a novel method, based on the combination of a deep residual neural network (ResNet) and lower and upper bound estimation (LUBE), ...
The proposed lower upper bound estimation (LUBE) method constructs an NN with two outputs for estimating the prediction interval bounds. NN training is achieved through the minimization of a proposed PI-based objective function, which covers both interval width and coverage probability. The method ...
reliability analytically without concerning the structure of the complex system.The method has been applied to a real system and the reliability results are compared with those acquired by the classical method and the parametric method.The effectiveness and accuracy of the proposed method have been ...
As shown in Fig. 3, the lower and upper bound both consists of two segments in this case. Generally, we can get the expression of co(R L (c)) and ca(R U (c)) for other parameters α and m using similar method. Examples In the following, we give two examples as applications of...
Upper and lower bound estimationThe uncertainty research of hydrological forecast attracts the attention of a host of hydrological experts. Prediction Interval (PI) is a convinced method that can ensure the forecasting accuracy meanwhile take uncertainty range into consideration. While the existed ...
Epidemics in heterogeneous communities: estimation of R [sub 0] and secure vaccination coverage. Confidence regions for the upper bounds are derived, thus giving conservative estimates of R [sub 0] and the fractions necessary to vaccinate. [ABSTRACT ... Britton,Tom - 《Journal of the Royal Stat...
The first method is a product approximation which can be calculated recursively without introducing extra parameters. The second method is based on the upper and lower bounds of KL divergence, and the mean of these bounds provides an available approximation of the divergence. We demonstrate the ...
FRACTURE ESTIMATION: BOUND THEOREM AND NUMERICAL STRATEGY A bound analysis of fracture parameters is proposed. It is found that the lower bound for J -integral can be obtained by a compatible displacement finite e... CC Wu,QZ Xiao,ZR Li - 《Computational Mechanics in Structural Engineering》 被...
An Eigenvalue Estimation Method of Weinberger and Weinstein's Intermediate Problems A method of H. F. Weinberger for calculating lower bounds to eigenvalues of semi-bounded self-adjoint operators is given a new formulation in an operator s... David,W.,Fox,... - 《Siam Journal on Mathematical...
A method is presented to calculate approximate value of confidence lower limits making use of reliability test data of torpedo components. 提出了一种通过鱼雷各部件可靠性试验数据来计算鱼雷系统可靠性近似置信下限的方法。 3. For the given reliability and confidence level, the point estimate and four ...
