It s a neural network decisor for Pareto set based in cross-correlation between a specific noise model and sucessive aproximation errors of the neural network that generates each solution of Pareto set.

this document useful,to calculate radius in image

matlab关于主成分分析的代码，使用于经济医疗等分析(a program code on matlab of principal component,it s used in economic,healthy and so on.)

针对阵列信号处理中的相干源DOA估计问题，提出了改进的前后向空间平滑，并利用MUSIC实现DOA高精度估计(For coherent source DOA estimation in array signal processing, and put forward the improvement to the space before and after the smooth, and use the MUSIC to realize DOA estimate precision )
