Based on remote sensing(RS) and geographic information system(GIS) technology, the land use range and landscape pattern index were used to study the spatial-temporal change of land use in Pingdingshan mining area, Henan Province, China. We analyze the change of the range and spatial pattern based on remote sensing images in 1978, 1994 and 2006. The results showed: 1) The regional landscape were changed...
With the rapid development of internet and communication technologies, mobile computing has become a main computational method nowadays, and geographic information system based on mobile computing is the extension of mobile computing in the spatial information field. It can be forecasted that Mobile GIS will become the next luminescent point of GIS industry. This paper set forth the concept of mobile...
Least squares support vector machine (LS-SVM) has been widely used in engineering practice, using for reference algorithm of combinatorial optimization, this paper puts forward the combinatorial optimization least squares support vector machine algorithm (COLS-SVM). Based on algorithmic analysis of COLS-SVM, it can be used on individual credit evaluation and compared with Lagrange support vector machine...
LS-SVM(least squares support vector machine) has been widely used in engineering practice. However, the solving of LS-SVM still remains difficult under the condition of large sample. Based on algorithm of combinatorial optimization, this paper put forward the combinatorial optimization least squares support vector machine algorithm. On several different data aggregation of dimensions, the numerical...
