A novel band selection algorithm for hyperspectral dimensionality reduction by improving the firefly algorithm is put forward. Specifically, the framework which using bio-inspired algorithm for hyperspectral band selection is described; the between-class separability criteria such as Jeffreys-Matusita (JM) distance, transformation divergence (TD) are used for objective function. A HYDICE Washington...
With the development of the economy and rapid population growth, the range of contaminated groundwater is getting bigger and bigger. Groundwater pollution has a slow process, and it is not easy to find and difficult to control. Once polluted, it takes more than ten years, sometimes even decades to recover. Groundwater pollution has a close relationship with people's health. This paper mainly discusses...
Wireless Sensor Network (WSN) is the hot research topic. In order to adapt to the future development direction of WSN, this paper presented a movement control strategy based on virtual repulsion in Multi-tier Mobile Sensor Network. The strategy first used a hierarchical node aggregation algorithm to divide all sensor nodes into many communication clusters in the monitoring area. It combines virtual...
