Tree Augmented Naive Bayes Classification (TANC) is not very well to deal with continuous data and it ignores partial data in the absence of data attribute value and this can reduce the result accuracy. To resolve this problem, an improved algorithm based on C4.5 is proposed in this paper. The proposed algorithm firstly modifies the available training data according to the predictions of C4.5, then...
Although polarization and spectral information utilization has been received great attention with the sensor and detection technology advance, few results are showed to jointly utilize both of this information in targets classification. Polarization and spectral information reveals two different aspects of one single target, and therefore, if both of information is properly used, good performance...
A two-dimensional ultra-precision positioning system with high-speed and large-range which can be used in a micro-nanometer machining has been studied in this paper. The macro-micro dual-drive system is used to satisfy these positioning requirements. Because of the strong nonlinearity of the piezoelectric devices, such as the hysteresis and the creep, and the influence of the highly accelerated run...
According to the positioning accuracy requirements of the two-dimensional precision positioning system with high speed, wide platform, large range and linear motor driving, an intelligent positioning control system based on the linear motor is studied in this paper. The precision positioning experiment is also conducted. The experimental result shows that the positioning accuracy and the dynamic performance...
According to the positioning accuracy requirements of the two-dimensional precision positioning system, a two dimensional intelligent positioning control system is used in our study. The precision positioning experiment is also conducted. The experimental result shows that the positioning accuracy and the dynamic performance of the fuzzy neuron self-adaptive PID control system in high-speed movement...
