Probability density estimation for object recognition in unmanned aerial vehicle application 概率密度估计在无人机目标识别中的应用
V. Kharchenko, A. Kukush, N. Kuzmenko, I. Ostroumov
The problem of object recognition in Unmanned Aerial Vehicle application is considered. Probabilistic Bayesian approach in object recognition is used. The accuracy of object recognition depends directly on the quality of prior data and accuracy of object parameters description. An approach for probability density estimation based of regression model is represented. Probability density functions are estimated by learning samples. The proposed approach is verified by laboratory experiment with video recording of object in rotatable platform.

Use of non-normalized fuzzy sets membership functions in automated control tasks 非归一化模糊集隶属函数在自动控制任务中的应用
Alexander Gaisha, Elena Gaisha
Proposition to use membership functions of fuzzy sets without limitation between 0 and 1 is presented. It is established that there are real control tasks and data analysis tasks in which it is expedient to use membership function values from 0 to infinity. Example with ship stabilizer fuzzy control system is considered in detail. Article may be useful for engineers who want their fuzzy control systems take into account possible extraordinary values of input variables, but in its everyday work remained within the reasonable ranges of values.
