Modern learning is impossible without automated knowledge testing systems. At present, the most progressive are adaptive models in which complexity of tasks varies depending on correctness patient’s answers. This article describes development an intelligent system using a fuzzy mathematics device. An has been developed; module that implements expert uses production base rules. The input paramet...
Due to widespread use of Global Positioning System (GPS) in different applications, the issue of GPS signal interference cancelation is becoming an increasing concern. One of the most important intentional interferences is spoofing signals. An effective interference (delay spoof) reduction method based on adaptive filtering is developed in this paper. The principle of method is using adaptive f...
this paper deals with leader-following and leaderless consensus problems of high-order multi-input/multi-output (mimo) multi-agent systems with unknown nonlinear dynamics in the presence of uncertain external disturbances. the agents may have different dynamics and communicate together under a directed graph. a distributed adaptive method is designed for both cases. the structures of the contro...
This paper introduces a new logic approach to reason about the dynamic belief revision by extending wellknown Aucher’s dynamic belief revision approach to fuzzy environments. In our system, propositions take a valuation in linguistic truth term set, and a belief revision is also in a qualitative way. Moreover, we reveal some properties of our system in epistemic style and do a comparison betwee...
Despite providing robustness, high-gain observers impose a peaking phenomenon, which may cause instability, on the system states. In this paper, an adaptive saturation is proposed to attenuate the undesirable mentioned phenomenon in high-gain observers. A real-valued and differentiable sigmoid function is considered as the saturating element whose parameters (height and slope) are adaptively tu...
Potato image segmentation is an important part of image-based potato defect detection. This paper presents a robust potato color image segmentation through a combination of a fuzzy rule based system, an image thresholding based on Genetic Algorithm (GA) optimization and morphological operators. The proposed potato color image segmentation is robust against variation of background, distance and ...
Many people believe in streaks. In basketball, belief in the “hot hand” occurs when people think a player is more likely to make a shot if they have made previous shots. However, research has shown that players’ successive shots are independent events. To determine how age would impact belief in the hot hand, we examined this effect across the adult life span. Older adults were more likely to b...
In order to solve the problems that traditional single-machine methods find it difficult complete task of emotion classification quickly, and time efficiency scalability are not high; a microblog analysis method using improved deep belief network (DBN) under Spark platform is proposed. First, Hadoop distributed file system used realize storage text data, preprocessed data dictionary converted i...
