With the development of online tourist, Tourist Recommender System (TRS) has become a hot research topic. This paper presents a TRS and considers a new tourist trip design problem (TTDP), taking into account the compactness of the trip. To solve this problem, fireworks algorithm (FWA) is adopted. As a meta-heuristic method, FWA has been widely used in continuous problems, while TTDP is a discrete...
Virtual view synthesis is the key technology of the current Three-dimensional Video applications and future Free Viewpoint Television. And virtual viewpoint synthesis based on depth image by using two adjacent reference two-dimensional viewpoint color images and corresponding depth images to render the intermediate view is the most potential algorithm for virtual view rendering. First, a modified...
This paper put forward a repetitive control algorithm based on virtual resistance to the question that improving the gain characteristic of LCL filter circuit results in increased power lose. Apply the algorithm to embedded repetitive control system, and one new repetitive controller based on virtual resistance is formed, then use the controller to control the grid-connected part of PV system. Simulation...
The paper focuses on some key problems in Web communities' discovery. Based on topic-oriented communities discovery, we analyze some insufficiencies of CBG (complete bipartite graph) in trawling method. The conception of x-core-set is introduced, instead of CBG, it is more reasonable as a signature of core of community. We construct a bipartite graph from a node x and then (i, j)pruning the graph...
