The paper explores a new method which is combined by the nearest neighbor classification method and the fuzzy classification method,and the paper is based on IKONOS remote sensing image,using the nearest neighbor classification method,the fuzzy classification method and the hybrid method to extract information from the image.

The data mining on outliers of time series of gas load is carried out using k-nearest neighbor,and the reasons induced outliers are analyzed.

After analyzing common arithmetic for data mining,this paper mines outlier data using k-nearest neighbor from the materiel consumption of blast furnace,from which attains the error data,then the found error data are corrected by the method of metal-material-balance.

Based on the nearest neighbor distance method,the characteristices of spatial distribution of landscape resources in Fujian Province were studied.

Based on this observation, an offset method is presented for computing the minimum distance between two planar algebraic curves.

The minimum distance computation problem has wide applications in CAD/CAM and computer graphics.

An effective and straightforward algorithm is developed for computation of minimum distance between two Bézier curves.

Research on the closest distance algorithms for two adjacent entities in spatial relationship;

The algorithm for finding closest distance from known point to known surface based on calculating high degrees equation set leads to big errors and a new method based on the Nelder-Meade algorithm was proposed.
