摘要
对于FCM类算法而言,种子的初始化是保证算法不陷入局部最优值和减少计算时间的关键.本文中提出根据密度分布特性的密度等高线来确定种子的选取不仅可以确定种子的个数,同时可以加快FCM算法的执行.
For FCM kinds of algorithms, initialization of seed is a key factor to reduce the computation time and to guarantee avoid ance of the local minimum. A new method of seed selection by density contour is presented in this paper, which can not only determine the numbers of seed but also expedite the execute speed of FCM algorithm.
