Particle Swarm Optimization (PSO) based Fuzzy c-means (FCM) methods typically use random initialization, and could incur substantial computation costs in processing big data, although PSO facilitates the global optimization, based on our previous work [1]. This paper further developed and evaluated our data density-pattern based algorithm to guide initialization and to achieve better computational...
Based on empirical studies, the feature of random initialization in Particle Swarm Optimization (PSO) based Fuzzy c-means (FCM) methods affects the computational performance especially in big data. As the data points in high-density areas are more likely near the cluster centroids, we design a new algorithm to guide the initialization according to the data density patterns. Our algorithm is initialized...
With the instruments become more and more intelligent, multifunctional, the pointer display way can not meet this kind of development. LCD, especially the lattice LCD with great display screen makes it possible to produce instruments with much more beautiful interface and much more information on the display screen. In this paper some algorithms on drawing dot, line, circle, and the averagely partition...
