In this paper an improved algorithm of computational verb PID controller is proposed. In the original design of verb PID controller, the modification of integral gain is coupled with that of the derivative gain. In this paper, the integral gain is modified independently by using a separated set of computational verb rules. The comparisons of tracking performance and robustness among conventional PID...
There are many algorithms for association rule mining, but in practice we usually face raw data that is inappropriate for these algorithms because of lacking a unified preprocessing framework. In this paper, a general framework for dynamic data processing is presented, which is based on computational verb theory (CVT). Linear standard computational verbs are used and computational verb similarities...
Gas recognition techniques are important for metal oxide sensors in practical applications because of their poor selectivities. The conventional solution is using sensor arrays instead of single sensors for pattern recognition. But this solution is expensive and the accuracy is affected by every single sensor in it. So developing recognition techniques based on single sensors is strongly needed. In...
In computational verb(CV) image processing, the evolving function of a spatial verb denotes the changes of gray-values along spatial coordinates. The spatial configurations and the changes of the brightness function as two kinds of the evolving functions of spatial verbs. In our previous work, gray level profiles and contour shapes were used to construct edge models for describing edges of image,...
Computational verb numbers, as a special kind of computational verb, play an important role in designing computational verb gain-scheduling PID controllers. In this paper, computational verb numbers in the form of “computational verb + real number” are used to construct control rules of PID controllers, and a composed computational verb similarity is designed for computational verb reasoning. Simulation...
In this paper, computational verb theory (CVT) is applied to the analysis of stock market data. By using CVT, stock market data are clustered into different categories and represented by typical curves for each category. In this paper, researches on the market data samples from Shanghai Stock Exchange in March 2010 are reported. Firstly, MATLAB programs are used to preprocess the stock data. The preprocess...
In this paper, a new image interpolation algorithm is proposed due to the inspiration of knowledge-based learning and dynamical control strategy which are based on computational verb theory. This algorithm takes gray level profiles and contour shapes as two processing factors. Experiments show that, with respect to the performance near edges of digital images, our algorithm is better than nearest...
The development and evolution of vocabulary is a very complex and dynamic process. The development of Chinese vocabulary is mainly that the monosyllabic words in ancient Chinese gradually evolved into disyllabic and polysyllabic words in modern Chinese. This paper attempts to analyze the evolving mechanism of computational verbs in Chinese, including merge of verbs, split of verbs. Furthermore, computational...
In this paper, a model of computational verb finite-state machines is introduced. This model extends fuzzy state machines with computational verb logic and is able to make transition bases on the dynamics of inputs and internal states. The model is very general and will provide a new perspective for solving problems in many fields.
Computational verb rules are efficient tools to represent dynamical experiences of a system in the form of natural languages. In this paper, a face-to-face collision resolving model based on an ultrasonic blind navigation system is built. The computational verb rule bases are constructed for the collision resolution and their validation is showed.
