Focused on the trouble of the features representation of merchandise in content-Based recommendation system, in this paper, the theory of vague sets, Gaussian function and characteristics of uncertainty were used to represent features with vague value. On this basis, the general steps of content-Based recommendation with Vague Sets were given in the paper, in order to get a new idea and method to...
The current UPnP service discovery algorithm in the presence of the service can cause severe drops in the digital home network. The reason is that the root devices instantly send delay sending response messages and randomly select independent response message congestion through simulation analysis. To solve these problems, an improved UPnP service discovery algorithm was given. Considering the length...
Artificial signals possess some certain chronological property-the cyclostationarity, with which the traditional DOA estimation can rarely reach the desired precision, or completely turns to be of no avail. Designated for removing the defect, this paper applies the Cyclic-Music algorithm to the MIMO radar's DOA estimation and verifies its effectiveness. Simulations show that the precision of MIMO...
Based on real-value vague sets risk preference score function, this paper presents an approach for determining scoring value of interval vague and applies it to multi-criteria decision making problems. The approach completely embodies risk preference of decision maker as well as the effect of various uncertain information to decision making. Finally, an example is given to illustrate the effectiveness...
In this study, we proposed a Fuzzy multi-criteria decision-making hybrid approach (FMCDM) which integrates the Fuzzy Analytic Hierarchy Process (FAHP) and the Fuzzy Technique for Order Preference by Similarity to Ideal Solution (FTOPSIS) to evaluate the severity of the damage of Typhoon in various provinces in China. In order to match the AHP method in the 1–9 criteria, the statistics data of typhoon...
