Analysis of Cloud workloads using data mining technology is critical for improving resource management. Unfortunately there is a lack of systematic approach to support the feature generation in comprehensive workload analysis. In this paper we propose a function based generalized feature generation method for the analysis of a one-month trace of a Google data center over 40 million task events across...
Natural disasters can lead to severe losses in human life and property. Because many factors combine in a disaster, such events are difficult to forecast accurately. A cooperative multi-classifier method is proposed in this paper to mine local area meteorological data. The proposed method is verified by the implementation of both base and integration classifiers. Experimental results indicate that...
Traditional rough set of noise data, the lack of adaptability, lack of flexibility or robustness, for the engineering data can not distinguish between equivalence classes of edge region of overlap with the collection, resulting in loss of many valuable engineering information. Strong noise in the actual engineering data over-fitting due to reduced ability to distinguish the object, its limitations...
Decision tree method is a powerful technology of decision-making system construction. The article introduces basic concept and algorithm of decision tree method first of all, then conducts data mining in economic statistical data through the introduction of decision tree method, and analyses the excavated information, thus proves that decision tree method can improve the quality of economic statistical...
Along with the fast developing of network technology, the number of Web page and user of network search become very enormous. In order to solve the problem of inefficiency and low precision in the search that users have different demand and knowledge background, this paper presents a new text model called vocabulary semantic net which can be applied to build personalized search engine and tested with...
Tetris game is one of the most popular and interesting computer game. To reduce the cost and simply the circuit, a Tetris game system is developed base on single chip microcomputer and light-emitting diode dot matrix module. The hardware and application software of system are designed and the whole principle of various details in the system is described. The system including five parts: single chip...
Delay tolerant networks are a type of wireless mobile networks that do not guarantee the existence of a path between a source and a destination at any time. In such a network, one of the critical issues is to reliably deliver data with a low latency. Naive forwarding approaches, such as flooding and its derivatives, make the routing cost (here defined as the number of copies duplicated for a message)...
Delay tolerant networks (DTNs) are wireless mobile networks that do not guarantee the existence of a path between a source and a destination at any time. When two nodes move within each other's transmission range during a period of time, they can contact each other. The contact of nodes can be periodical, predictable and nonpredictable. In this paper, we assume the contact of nodes is nonpredictable...
This paper treat the query sentence as common sentence segmented from multi-documents set for multi-document summarization, and mixed it into sentences set, then this paper create efficient cluster algorithm to cluster all the sentences, The clusters which contain the query sentence will be merged to one cluster, and modified MMR will be used to extract summary sentences. Experimental result shows...
Moving object detecting is one of the current research hotspots and is widely used in fields such as computer vision and video processing. The study on image processing toolkit using computer language Matlab was conducted to perform moving object detecting technical processing on video images. First, video pre-processing steps such as frame separation, binary operation, gray enhancement and filter...
The signal processing of Lamb wave is complex because of its multi-mode and frequency-dispersion characteristics. A method to analyze symmetrical single-mode ultrasonic Lamb wave in the time domain is presented. Based on the analysis of frequency-dispersion characteristic of symmetrical mode Lamb wave, we deduced the half analytic expression of its time signal, and implemented simulation computation...
Intelligent video monitoring is a new technology originally developed on the basis of video image processing technology. Aiming at the defects of monitoring conducted by man in the conventional practice, the automatic alarming technology based on intelligent video monitoring was studied. Frame difference-based dynamic background refreshing algorithm was applied to monitored scenes to carry out cutting...
