Up to now, the World Wide Web (WWW) grows into a large hyperlinked corpus with more than 800 million pages and 5 600 million hyperlinks. Moreover, it is obviously impossible that any global ‘planning’ can be imposed on the creation of such a corpus. This brings some challenges to many research fields on the World Wide Web. On the other hand, the hyperlinked(More)
In this paper, the authors attempt to revisit the behaviour of HITS from a different point of view. Namely, a similarity-based analysis model is proposed to observe the distillation procedure. By defining a generalized similarity, an algorithm is presented, which can improve the quality of distillation using only hyperlinks. A topic exploration function is(More)
3-D Object detection plays an important role in automation industry. It is a big challenge to detect 3-D object in images without knowing its pose because under this condition, the appropriate 2-D template cannot be obtained. In this paper, we propose a 3-D object detection method based on line sets matching. The algorithm uses line segments to represent(More)
This paper presents a method of optimized PID parameter self-adapted ant colony algorithm with aberrance gene, based on ant colony algorithm. This method overcomes genetic algorithm’s defects of repeated iteration, slower solving efficiency, ordinary ant colony algorithm’s defects of slow convergence speed, easy to get stagnate, and low ability of full(More)
