The problem of node classification has been widely studied in a variety of network-based scenarios. In this paper, we will study the more challenging scenario in which some of the edges in a content-based network are labeled, and it is desirable to use this information in order to determine the labels of other arbitrary edges. Furthermore, each edge is associated with text content, which may correspond...
Aiming at disadvantages of labor and time consuming of traditional tea classification method, this paper proposes a tea variety classification algorithm that integrates spectral and image characteristics with Mengding Mountain Huangya tea, Zhuyeqing tea and Ganlu tea of Ya'an City, Sichuan Province as objects. It firstly collected the hyperspectral images of tea samples with “GaiaSorter” hyperspectral...
Pixel purity index (PPI) is a very popular endmember finding algorithm due to its availability in ENVI software. It is also very useful technique to find a feasible set of potential target signal sources without prior knowledge. This paper presents a new application of PPI to detection of significant bands by orthogonal projection (OP), referred to as PPI-based band detection (PPI-BD). Its idea is...
The signature-based intrusion detection is one of the most commonly used techniques implemented in modern intrusion detection systems (IDS). Being based on a set of rules, i.e., attack signatures, the accuracy and reliability of IDS detection heavily depend on the quality of the employed rule set. In this context, any conflicts that arise between rules create ambiguity in classification of network...
To reduce the bandwidth requirement and the size of frame memory for video decoding, embedding a compressor/decompressor on the chip is a well-known solution. Video compression has been developed for a long time and numbers of algorithm have been proposed. Those algorithms show us that enhancing the complexity can reach better performance. However, algorithm with higher complexity is more difficult...
