Development of data mining application is very important for the telecommunication enterprise, which is a typical data-intensive industry. Customer segmentation can help analyze customer composition accurately and promote the quality of service and marketing. Using K-means clustering and the commercial automatic data mining tool KXEN, the paper proposes a resolution of customer segmentation for Changzhou...
Similarity measure is one of the core problems in data mining research on time series. Both Euclidean Distance and Dynamic Time Warping methods are widely used in similarity measure, which have their own limitations. Based on the symbolic time series data, this paper creatively brought forward a new kind of similarity measure framework SFVM (SAX Feature Vector Model). Based on the architecture of...
The improvement of concurrent degree supported by cooperative design leads to redundant reciprocating work. Degree of maturity with instant and numerical indicator is a solution to the drawback. A synthesis assessment method was proposed, aiming at the requirement of maturity indicator in airplane cooperative design. The method gave maturity degree of component/part combined physical readiness, implementation...
Traditional statistical data processing approach needs to know the distribution regularity of samples. But in the antiradiation missiles (ARM), when aerial defense radar uses active-decoying, the sample distribution regularity usually can't be known or has many likelihoods. To improve the precision and the stabilization of the angle-measure in the active-decoying environment, a grey processing approach...
With the acceleration of urbanization process and the booms in domestic infrastructure investment, the amount of civil engineering projects and infrastructures increase with years. In this context, how to lower the energy and environmental impacts of proposed project while achieving an optimization of owner's investment capitals has become a research focus with both theoretical and practical significance...
With the booming of the electronic payment industry in China, an effective regulation is in urgent need in order to support e-commerce development as well as to avoid potential financial risks. In response, information systems play an essential role in helping the authorities achieve the mission. This paper proposes a knowledge-based conceptual model for e-payment supervision. To align with the supervisory...
This paper analyzes the disadvantages of current popular database connection pooling technologies according to the special requirements of NMVS (Non Motor-Vehicle System) system and puts forward a new proposal of self-adaptive database connection pooling. This new proposal can dynamically adjust XML configuration parameters based on application scope of NMVS, and then select the corresponding management...
According to the characteristic of the Chinese speech, we propose a method of retrieving the Chinese speech based on wavelet transform in this paper. At first we preprocess the data in the warehouse to provide the high quality speech data. And then we divided the speech samples into subsections and pick up the character of them. Finally, based on the Euclid distance of scale parts, we retrieve the...
This paper proposed a new algorithm named GSP-K, which is a peer caching algorithm based on global segment popularity for P2P VoD system. This algorithm evaluates the cache utility of media segment via gathering the statistics of media segment popularity globally, and makes the numbers of a media segment copies in the whole system vary directly with itpsilas cache utility. The simulation experiments...
