The area under the curve (AUC) of the receiver operator characteristic (ROC) graph is regarded as an objective measure of the discrimination accuracy of predictive models. AUC scores calculated from background values, or pseudo-absences, have been proposed as a method of model selection for speci...
4) The accuracy of the coastal wetland NEE prediction model based on convolutional neural network was better than other similar models’, which shows that the model is applicate in NEE prediction modeling. This study provided a reference for NEE prediction modeling and analysis of coastal wetland ...
How many databases can I create at most in a TencentDB for SQL Server instance? If there are too many databases, the TencentDB for SQL Server instance performance will drop, and more resources such as worker threads will be used. If the limit on the number of created instances is exceeded...

Li et al.11 constructed an optimal decision model for industrial product design schemes based on a multi-level gray comprehensive evaluation method, completed priority ranking of the design schemes of multi-rotor drones, and verified that the results were in accordance with the entropy-weight ...
1. The selection decision is based on multiple criteria, which can compensate for each other. This generates a negative correlation between predictors which attenuates the predictor-outcome correlation for each of them. 2. As outcome data are not available for rejected applicants the range of predic...
What I want is that when a new object is created in the object type "Phone" and then for example under "Brand" Company 1 is selected, that only certain models (all model from Company 1) are listed (and not the models of Company 2) Is this possible to implement in...
