In this paper
a new method is proposed to improve the classification performance of hyperspectral images by combining the principal component analysis (PCA)
genetic algorithm (GA)
and artificial neural networks (ANNs). First
some characteristics of the hyperspectral remotely sensed data
such as high correlation
high redundancy
etc.
are investigated. Based on the above analysis
we propose to use the principal component analysis to capture the main information existing in the hyperspectral images and reduce its dimensionality consequently. Next
we use neural networks to classify the reduced hyperspectral data. Since the back-propagation neural network we used is easy to suffer from the local minimum problem
we adopt a genetic algorithm to optimize the BP network's weights and the threshold. Experimental results show that the classification accuracy is improved and the time of calculation is reduced as well. 2012 IEEE.

To deal with the defects of BP neural networks used in balance control of inverted pendulum
such as longer train time and converging in partial minimum
this article reaLizes the control of double inverted pendulum with improved BP algorithm of artificial neural networks(ANN)
builds up a training model of test simulation and the BP network is 6-10-1 structure. Tansig function is used in hidden layer and PureLin function is used in output layer
LM is used in training algorithm. The training data is acquried by three-loop PID algorithm. The model is learned and trained with Matlab calculating software
and the simuLink simulation experiment results prove that improved BP algorithm for inverted pendulum control has higher precision
better astringency and lower calculation. This algorithm has wide appLication on nonLinear control and robust control field in particular. 2011 IEEE.
