Subspace learning has been widely used in signal processing, machine learning, computer vision and so on. Matrix rank minimizing is a fundamental model. Nuclear norm is a convex relaxation for rank minimizing. In this paper, we propose a polynomial function to smoothen the nuclear norm. Lagrange multipliers method is employed to solve the problem. The optimal solution is obtained by iterative procedure...
Due to the diversification of software and hardware resources in cloud and ever-changing demand for deployment, Hadoop deployment is faced with great challenges in difficulty and complexity. Most of present researches lie in environment configuration and parameter setting of deployment, they do not take into account diversification of infrastructure and scalability issues in cloud. In order to quickly...
Computation offloading is a promising way to improve the performance as well as reducing the battery power consumption of a mobile application by executing some parts of the application on a remote server. Recent researches on mobile cloud computing mainly focus on the code partitioning and offloading techniques, assuming that mobile codes are offloaded to a prepared server. However, the context of...
Cloud Computing is evolving as a key computing paradigm for sharing resources. One type of Cloud, which provides platform resources including all the elements of application runtime environment, is regarded as PaaS Cloud. The management of PaaS Cloud is a complex task, up to the point, where manual operation is hard to be cost effective. As the application runtime environment is supported by a set...
Repetitive vector is one of the important properties of the Petri net basic net, and it can be used to determine the properties of a net language. Unfortunately, a Petri net system usually has infinite effective controlled repetitive vectors. Therefore, it is necessary that all the effective controlled repetitive vectors can be represented with limited entities. Thus, this paper proposes the set of...
Statistics of science and technology is not only a daily task of technology sector, but also an important reference for government decision. How it is possible to deal statistics data by computer system automatically? It is a goal for information system specialists and scientific and technical workers. We studied many documentations and reports of statistics for science and technology in Kunming and...
Formal languages involve many concepts such as string, grammar and semantics which are able to be described by “Categories”. This paper provides two categories which are used for grammar and semantics in a context-free language, and the syntax analysis issue has been discussed in detail. This information may be useful for researcher concerning formalization methods.
Textures is one of the keys in image pattern recognition. To realize the computer vision for textures, it is necessary that understand textures rationally. The key of understanding textures is explaining them by the human's signs and approaches. We believe the mathematical structure of categories is similar to human's rational intelligence. In this paper, we describe the common textures by notes and...
Hydrologic processes are sensitive to the spatial distribution of hydrologic parameters in watersheds. A distributed hydrologic model which can simulate various components of a watershed hydrologic cycle such as surface water, channel water, soil water and groundwater as well their interactions is used to simulate various hydrologic processes in the Meilin watershed in this paper. The parameters with...
