This study proposes a Task and Motion Planning (TAMP) method with symbolic decisions embedded in a bilevel optimization. This TAMP method exploits the discrete structure of sequential manipulation for long-horizon and versatile tasks in dynamic envir

The Huaibei coalfield is an important coal base and one of the hot spots of coalbed methane development in China. Therefore, a detailed understanding of gas occurrence in the Huaibei coalfield is of great significance. This paper analyzes the gas occ

Multiple sets of thick coal beds characterized by simple structure and shallow burial depth were developed in the Early and Middle Jurassic strata of the Ordos Basin, northwestern China. The huge reserves of this high quality coal have a high commerc

Summary We consider the problem of empirical Bayes estimation of multiple variances when provided with sample variances. Assuming an arbitrary prior on the variances, we derive different versions of the Bayes estimators using different loss functions

The Huainan-Huaibei coalfield in the Anhui Province in China is an important coal base and comprises a large portion of the coalbed methane (CBM) resources in China. Therefore, it is of great significance to evaluate the CBM resources and categorize

For the single index model y = f(βτx, 𝜖) with Gaussian design, where f is unknown and β is a sparse p-dimensional unit vector with at most s nonzero entries, we are interested in testing the null hypothesis that β, when viewed as a whole vecto

For multiple index models, it has recently been shown that the sliced inverse regression (SIR) is consistent for estimating the sufficient dimension reduction (SDR) space if and only if [Formula: see text] , where p is the dimension and n is the samp
