In order to further improve the accuracy of personalized recommendation algorithm in social network, on the basis of summarizing the traditional recommendation algorithm, this paper introduces the social relationship between users, the trust propagation mechanism and time sequence information and user-item score matrix information are fused to the probability matrix decomposition model, a new personalized...
In utility computing models, users consume services based on their Quality of Service (QoS) requirements. QoS provides a basis for task scheduling, but it also makes task scheduling problems more complex. In this paper, we present a heuristic scheduling algorithm, named Budget-Deadline Constrained Workflow Scheduling (BDCWS). The algorithm calculates the task priority by a new method to balance the...
While there is a large amount of text data on the Internet, people need to organize the text data with experienced category. However, the flat structure of categories could not satisfy the modern information management. To solve this problem, we propose a hierarchical classification process with a strategy, called candidates, used to relieve the blocking problems. Besides, we establish the description...
To model the cooperative behavior under the realistic world, we put forward a high clustering network model with the property of adjustable power-law, and analyze the evolution of the prisoner dilemma game on this improved HK network model. Using simulation experiments, we investigate the effect of high clustering property of this network on the cooperative behavior. Extensive simulations indicate...
Degree distribution is an important characteristic of complex networks. To better understand the mechanism of complex networks, it is necessary to analyze their vertex-degree sequences. We had shown before that, for a complex network model with power law distribution or exponential distribution or general degree distribution, the length l of the unequal vertex-degree sequence is of order logN. Poisson...
Facilitated by the emerging technologies of cloud computing, vehicular cloud computing (VCC) is being expected to be a new paradigm to create a new situation for vehicular data services. However, with the increasing popularity of vehicular cloud services, accessing vehicular terminals and produced mobile data are experiencing tremendous growth, therefore, how to provide enough capacity for all access...
The control packets in the Data Center Networks (DCNs) have to contest with the data packets although they are usually much shorter in size and much more important in network management. Moreover, the uneven distribution of the packets may create potential hotspots in the DCN which could degrade network performance drastically. To bridge these gaps, a few proposals have been put forward to construct...
Thanks to the ubiquitous computing, the scale of data collection in various fields has been growing rapidly. Medicine is one of the fields that can benefit from the big data. However, it is faced with a big challenge because medical datasets are normally in high dimensions. Therefore, reducing dimensionality and finding the optimal set of features or attributes is of great importance. This paper presents...
In this paper, a reference line guided Pareto local search (RLG-PLS) is proposed for combinatorial bi-objective optimization problems (CBOPs). RLG-PLS uses a set of predefined reference lines to guide the search direction and maintain the diversity of the population. Two populations are evolving in RLG-PLS, i.e., 1) the external population (EP) maintains the nondominated solutions that are closest...
