基因芯片数据多尺度分析的y～n曲线模型

摘要

针对离散的基因芯片表达数据难以进行系统分析的问题,提出基因芯片数据的y～n曲线模型,将级基因芯片数据转化为唯一的一列信号,从而可以对其进行多尺度分析.对人类胎儿脑发育过程中大脑皮质基因表达基于y～n曲线模型进行小波多尺度降噪,结果证明,y～n曲线的降噪效果比用基因芯片原始数据更好.%The model of y～n curve is set up to solve the problem that discrete gene chip data are difficult to be systematically analyzed, which makes the data be changed into a row of sole signal, and can be studied by multi-scale analysis. Results of denoising the cerebral cortex gene expression of developing human brain based on wavelet multi-scale analysis show that the denoised effect of y～n curve is better than that of raw data.
