Recent years have witnessed the prevalence of networked data in various domains. Among them, a large number of networks are not only topologically structured but also have a rich set of features on nodes. These node features are usually of high dimensionality with noisy, irrelevant and redundant information, which may impede the performance of other learning tasks. Feature selection is useful to alleviate...
Dynamic uplink and downlink reconfiguration is studied as an effective method to improve the system packet throughput performance in the LTE Heterogeneous Network. There are various kinds of traffic with different quality of service requirements in the practical wireless network, which has not been fully considered by the existing resource allocation strategies for dynamic TDD. In this paper, a resource...
In order to meet the need of continuous development of three dimensional (3D) Geographic Information System (GIS), we apply an algorithm that efficiently builds a compact sparse octree into GIS. The algorithm is based on the fast GPU hardware rasterization, which builds the octree structure from top level to bottom level at the same time. Therefore the graphics based parallel algorithm can accelerate...
Online Social Networks (OSNs) have provided an infrastructure for a number of emerging applications in recent years, e.g., for the recommendation of service providers, where trust is one of the most important factors for the decision-making of service consumers. In order to evaluate the trustworthiness of a service provider (i.e., the target) without any prior interaction with a service consumer (i...
With the development of automotive industry and transportation, the safety of transportation is huge invisible trouble by bringing great convenience to human being for many years. As result, the reappearance for the simulation of traffic accidents scene is essential. On the other side the reappearance of traffic accidents is not only the method to evaluate the responsibility, analysis the cause, but...
