(5) In research of the information of expression, including semantic feature, such as color, texture, border, as so on, spectral mixture feature, high- dimension data feature extraction,Gis data and expert information,presents two approach by using Gis data for image mining—straightway classifying in form of logistic waveband and systematizing applicat ion in the spatial database. Designs the using model or system framework.
But, when the radial basis function neural network is used to solve the classification of high-dimension data, the generalization of neural network determined by past center-chosen algorithms is very poor.
Because it has quite perfect theoretical properties and good learning performance, and can solve some practical problems such as a little sample, non-linear, high-dimension and part minimized value, SVM becomes the new research hotspot after the research of Artificial Nerve Net.
Based on the characteristics,such as topology holding,information bond and high-dimension data vector quantization,which the self-organizing feature mapping network has,the visual topology mapping pattern used for partitioning system voltage was set up meanwhile the secondary voltage control partition was carried out basing on the topology mapping image,after that It is presented that entropy is used to search dominant node as measuring variable.
In one of previous papers by tbe same author was proposed a simplified system describedwith lower order transfer functions, and yet the system obtained might happen to be not so stable.In this paper and for the purpose of tackling this problem, a new frequency simplification techniquewith stability into consideration is presented to simplify a transfer function of high dimension intoone of lower dimension by means of least squares so as to achieve a stable system.
A decomposition-coordination algorithm for solving large-scale linear programming problem has been proposed to overcome the computational difficulties due to high-dimension. The model-coordination method is adopted, and direct search method is used for the coordinator to improve the coordinating variables.
The judgement of the stability of higher dimension large scale grey systems is simplified to that of lower dimension subsidary equation groups by using the discontinuous di fferentiable V function and the comparison principle, so that the given conditions of the stability of systems are omitted.
