Indoor localization based on existing Wi-Fi Received Signal Strength Indicator (RSSI) is attractive since it can reuse the existing Wi-Fi infrastructure. However, it suffers from dramatic performance degradation due to multipath signal attenuation and environmental changes. To improve the localization accuracy under the above-mentioned circumstances, an improved Spearman-distance-based K-Nearest-Neighbor...

This paper introduces association rules and Apriori algorithm in data mining, with the improved Apriori algorithm, association rules being applied in the analysis of the skills in football match have been realized, and the analysis result will help to improve the rate of football players shot-goal, which provides theoretical basis for the coaches training football players.
Digital images are facing trustworthy crisis with the emergence of various digital image process tools and steganography tools. Current digital image forensic methods can not evaluate the digital image's trustworthiness. Base on Dempster-Shafer (D-S) evidence theory, this paper proposed a new model which can effectively evaluate digital image trustworthiness. Instead of using Dempster's original rule...
