This paper introduce the theory of convex hulls into the semi-supervised clustering, and through combining them, we come up with a new thought to the semi-supervise clustering. Then we verify the feasibility of the convex hull in the semi-supervised clustering through experiment which be carried in the two dimensional space.
Traditional methods using for the design of tobacco leaf groups blending depend mostly on expert experiences. But they are lack control of the product quality and proved inefficient in practice. In this paper, we use the modified GA and PSO algorithms to help to optimize the leaf groups. The experimental results demonstrated that the modified GA and PSO algorithms are faster and more accurate when...
Similarity-based search has been a hot research topic for a long history, which is widely used in many applications. The large scale restricted floating sensor (RFS) network is an important model in offshore data collection . This paper constructs a new fuzzy similarity measures based on distance. This work provides a theoretical guidance for constructing a fuzzy query processing strategy for our...
The large scale restricted floating sensor (RFS) network is an important model in offshore data collection [1]. Due to the mobility and the large number of sensors, improved techniques are needed to deal with uncertainty and mass queries. As a theoretical basis, this paper constructs a general fuzzy similarity measures based on distance. With examples we illustrate that some common similarity functions...
