With the increasing availability of graph data and widely adopted cloud computing paradigm, graph partitioning has become an efficient pre-processing technique to balance the computing workload and cope with the large scale of input data. Since the cost of partitioning the entire graph is strictly prohibitive, there are some recent tentative works towards streaming graph partitioning which run faster,...
In this paper, we proposed a global convergence of an improved filter method of feasible direction for solving inequality constrained optimization. At every trial point, it is only necessary to solve one QP sub problem with equality constraints. On contrary the traditional SQP algorithm, we use filter method with the new SQP algorithm, which avoid Maratos effect. Under some reasonable conditions,...
In this paper, a new abnormal activity detection algorithm is proposed for multi-camera surveillance applications. The proposed algorithm models the entire scene covered by the multi-camera system as a network. In this network, each node corresponds to a segmentation of the entire scene and each edge represents the activity correlation between the corresponding segmentations. Based on this network,...
With the development of SOC designs, modern floorplanning typically needs to provide extra options to meet the different emerging requirements in the hierarchical designs, such as boundary constraint for I/O connection, clustering constraint for performance and reliability, etc. This paper addresses modern floorplanning with boundary clustering constraint. It has been empirically shown that the modern...
