Pollen-based reconstruction of palaeovegetation at 6 kaBP shows that the broad-leaved evergreen and deciduous forest zones as well as the mixed needle-leaved and deciduous forest zone expanded successively northwards to a large extent when compared with the present in China, suggesting a warmer-than-present winter and summer in China.

Study on case retrieving technique based on multi-chaotic BP neural network;

The data can be broadly classified as fuzzy sets by using the classification property of the BP neural network.

Research on xx gut tube s lifespan stepwise prediction based on BP network and polynomial fit;

When vibration drilling simulation and parameter optimization by Artificial Neural Network are carried out,the general method of parameter optimization modifies the trained BP Network,using the anti mapping capacity of the trained BP Network.

In this paper,the clustering ability of Kohonen network and the nonlinear similarity function of BP network are discussed,and a load day model is proposed.

Application of artificial neural net to geological mapping: setting up and utilization of backward propagating (BP net)model;

Through the study of rule of invariant moments and structure character of BP nets,a novel method of targets recognition based on multiple BP nets is proposed.

The paper chiefly discusses affine invariant moments and the ANN application in the pattern recognition, even simulating the classifier with the BP net and BPX arithmetics.
