Multi-label learning is popular in current research of machine learning areas, and there have already been many methods using label relationship to solve multi-label problems. However, the meaning of their relationship is not so obvious that it's hard for us to know the fact among labels. Besides, with the development of multi-label learning, hierarchical multi-label classification is a new research...
Smart-phones are becoming our constant companions, they are with us all of the time, being used for calling, web surfing, apps, music listening, TV viewing, social networking, buying, gaming, and a myriad of other uses. Smart-phones are a technology that knows us much better than most of us could imagine. Based on our usage and the fact that we are never far away from our smart phones, they know where...
ISO-surface extraction is an effective manner to study the visualization of three-dimensional data. To solve the ambiguity question of the existing ISO-surface extraction algorithms, an efficient ISO-surface extraction method which uses saddle points to ensure the topology correct is proposed in this paper. The experiment shows that the speed of the algorithm is quietly improved whenever the given...
A new and rapid scheme for detecting vehicles based on video by single camera at urban intersection is proposed. Firstly a rapid judgment algorithm of vehicle direction is introduced, with motion object segmentation by means of frame-difference method and morphology. It extracts the unique interested region from multiple objective through the modified region-growth algorithm, gets motion direction...
The domain knowledge has a direct impact on the result of question - answering (Q & A) in the restricted domain question answering system (QA). In this paper, a method of answer extraction for domain Chinese question-and-answer (Q&A) is proposed, which based on the analysis of interrogative sentence and the answer type, carrying on the text retrieval with the help of the domain knowledge and...
Since Witsenhausen put forward his remarkable counterexample in 1968, there have been many attempts to develop efficient methods for solving this non-convex functional optimization problem. However there are few methods designed from game theoretic perspectives. In this paper, after discretizing the Witsenhausen counterexample and re-writing the formulation in analytical expressions, we use fading...
Digital watermarking is considered as an efficient way to protect copyright of digital products. According to human auditory system (HAS), digital audio watermarking will be performed well by making use of auditory masking. Binary watermark information was embedded by classical quantization method in DCT domain after scrambled by Logistic map in chaos theory. Based on HAS and chaos theory, the proposed...
Iso-surface extraction is a standard visualization method for scalar data. A widely used iso-surface extraction algorithm is called Marching Cubes algorithm(MC). Based on the analysis of the MC algorithms used in the construction of value surface, it is proposed that the related point search algorithm and mid-point of linear interpolation improve the reconstruction rate and visualization. The selection...
One key matter we meet when classical logic is used in analysis and information mining to massive knowledge system is the problem of Scotus Law. Up to the present, the existent resolvents are far from our logical intuition. This paper gives a new strategy - to build an intuitive implication logic system, D, in which: (I) the property of implication should be in accordance with intuition; (II) the...
In order to improve the precision and real-time character of the traditional video-based traffic detector, a novel vehicle detection system based on line scan camera is developed. In this system, the vertical view images of vehicles are captured by two line scan cameras which are mounted on the pole's arm over the roadway; The distance between two cameras is 2 meters along the road. The vehicle's...
Multi-loop closed production systems widely exist in different industries, such as semiconductor assembly and test factory. Measuring the system performance is rather hard because of the complex interaction among the loops, but very important for the design, improvement and control of the production systems. In this paper, we propose an approximation method which is based on the overlapping decomposition...
Software testing is one of the most important techniques used to assure the quality of Web services at present. Test-data generation is an important topic in Web services testing. The quality of test data will influence the efficiency and cost when testing Web services. Based on the contract-based mutation testing technique, this paper presents a method of automated test-data generation for Web services...
At present, LUCC research becomes a hot problem. The research in our country focuses on the hot spots, fragile ecological environment and typical areas. In this paper, two remote sensing image respectively in 2000 and 2005 are used to analyze and assess the LUCC of the industrial zone by using the 3S technique means. The result is taken to support the data for the EIA and EM.
