The article introduce an advanced fuzzy cluster analysis algorithm base on fuzzy equivalence relation and the general research steps in detail, giving an example of realization different occupation introductions and fuzzy classification base on working achievements.
Network signature matching is an important task in many applications such as network security or traffic analysis, which generally rely on a flexible signature matching system to extract important packet information from each processed packet. This task is computation and data intensive, and requires significant processing time in sequential manner. In order to accelerate signature matching of giga-bit...
A self-adaptive road detection method based on vision and cluster analysis is proposed for automatic guided vehicles. Based on the K-means algorithm, an automatic sample selection method is developed — while moving, the vehicle automatically selects new road samples and takes cluster analysis at a specified time interval to get the latest road features. Verified by experiments on campus roads, the...
How to quickly and efficiently determine the subject category from a large amount of text is becoming an important challenge in text clustering. In this paper, One-Next text clustering algorithm based on the simplified cluster hypothesis is proposed. Meanwhile, a feature vector optimization method using grading feature vector extraction method is designed. Finally, the experimental results show that...
The article put forward a model for music emotion classification research. The main research contents are extracting the tempo from the MIDI file and defining the rhythm mutation degree. Let the two factors as the input of the music emotion model, we simulated the model in matlab. We used the improved support vector machine (SVM) classification algorithm to classify the emotion. In order to achieve...
It is urgent to find an automatic method of an automatic orientation calculation on the large-scale text in Chinese. Rather than comment their orientation directly in comment texts, people may express their orientation on topic by describe its features using orientation words. The describe word on features indicated their orientation. The orientation of comments on object is called topic orientation...
With geo-rough space theory and GIS technology, the study area is divided into regular grid cells, vulnerability assessment of geological hazards indexes system and vulnerability knowledge representation system and decision table in study area are designed. On this basis, specific algorithms for assessment indexes system optimization and weights confirmation are constructed. So that the vulnerability...
