The group structure of variables is commonly observed in many settings. The Group Lasso method discovers the group structure and performs group variable selection. We extend the Berhu penalty to the group selection settings and propose the Group Berhu method, including Group Berhu and Logistic Group Berhu model, which performs group selection similar to what the Group Lasso does. We use the block...
To keep balance of global and local searching ability, and to overcome the slow convergence and prematurely of particle swarm optimization, a new algorithm that isolation niches embedded in particle swarm optimization (INPSO) is introduced. Solving the heavy traffic problem in existing condition is also worth considering. In this paper, the method of two-intersections traffic controlling is proposed...
This paper is a description of the successful implementation of a model-merge approach for creating and updating the power system model of the new energy management system (EMS) for the China Southern Grid Company (CSG). The power-system model of this new EMS is a merged model of the five models in the five EMS's serving the five province power systems that constitute the China Southern Grid. The...
This paper presents an inversion model for vegetation moisture content based on remotely sensed data. Vegetation moisture content is an important index characterizing eco-water,which refers to the water closely related to vegetation and which plays an important role in adjusting and supplying surface water and ground water during the hydrological cycle. It shows the capability of the vegetation to...
Through researching the patterns and mechanism of life behavior of some animals, a knowledge processing system with biologic action feature was suggested by this paper, and the autonomic and creative features of the system were described. Following the thought of artificial life, the system was based on the rules and features that come from investigating the intelligent actives and behaviors of some...
Eco-water (layer) refers to the water body closely related to the ground vegetation layer. It is conserved in leaves, roots, vegetation humus layers and root soil layers, which is capable of precipitation interception and rivers and/or groundwater supplementation. As a challenging issue in the hydrological cycle field, the eco-water and its resource quantity are difficult to be quantified by ordinary...
