The invention discloses a method for predicting the coupling relationship between network resources and the environment, comprising the following steps: preprocessing the original incomplete parameter set through a multidimensional fuzzy mapping-based missing value processing method and a service expansion method to obtain preliminary parameters Set; through the feature construction method based on multi-dimensional environmental parameters, perform feature construction on the initially obtained parameter set to obtain data with stronger representation capabilities; integrate forward sequence search, backward sequence search, and simulated annealing algorithm to step S2 to obtain The characteristics of the data are dimensionally reduced, thereby reducing the variable space of each dimension and the complexity of multi-dimensional representation model training; the decision tree-based model training method is used to train, learn and predict the data, and realize the accurate description of network resources under the constraints of complex environments . The present invention can quickly and accurately complement missing values, and can improve prediction accuracy while achieving the purpose of improving model efficiency.

The invention relates to a fuzzy segmentation method for dynamic simulation validation of a large power system. Aiming at the problem of inaccurate dynamic simulation of the large power system and in consideration of a huge number of measurement data and model parameters of the large power system, the invention discloses a wide area pattern which represents the influence of the model parameters on a temporal and spatial dynamic characteristic of the power system; aiming at a certain type of elements of the power system, a fuzzy mapping relation between the model parameter and the temporal andspatial dynamic characteristic of the power system is obtained according to clustering analysis of the wide area pattern of the model parameter of the element on different nodes; and the model parameter of the element of the system is subjected to segmentation correction according to the degree of the mapping relation based on the measurement data, and a priority sequence of the segmentation correction is provided. In the invention, an effective method for dynamic simulation validation of the large power system is provided; and by applying the method, the dynamic simulation precision of the large power system can be improved.

The invention discloses an automatic-toning image processing method and system based on fuzzing. The automatic-toning image processing method includes the steps of respectively carrying out histogram statistic on the red channel, the green channel and the blue channel of an image, obtaining respective highlight pruning values and respective shadow pruning values of the red channel, the green channel and the blue channel, then generating a corresponding red mapping table, a corresponding green mapping table and a corresponding blue mapping table, further carrying out fuzzy processing on the mapping tables to obtain fuzzy mapping tables, and finally and respectively mapping color values of pixel points on the red channel, the green channel and the blue channel of the image according to the fuzzy mapping tables to obtain the final color tone of the image. In this way, the true tone of the image is better restored, tone distribution is more even, tone transition is more natural, and the effect is better.
