利用神经网络预测、分析蛋白质结构是当前蛋白质研究课题热点之一.本文根据蛋白质的亚细胞定位将亚细胞分为12类,并在SWISS-PROT数据库（2002年）选取其中三类原核亚细胞300个以及四类真核亚细胞380个,利用BP神经网络算法对其进行聚类分析.介绍了蛋白质的和BP神经网络的基本概念,并重点介绍了BP神经网络的原理和结构,给出特征参量氨基酸频率的数值统计,依此为依据对亚细胞进行聚类分析,得出对亚细胞分类的准确率,并在最后讨论误差的产生原因.

Answer 1

Making use of neural network projections,analysis of protein structure of protein is currently one of the hot research topic.According to the protein subcellular localization will be sub-divided into 12 categories of cells,and SWISS-PROT database (2002) select one of three original nuclear-300 and four types of cells of eukaryotic cells-380,with BP neural network algorithm Its cluster analysis.On the protein and BP neural network the basic concepts and focus on the BP neural network theory and structure,given the frequency characteristics of the parameters of amino acids numerical statistics,and so on the basis of sub-cells cluster analysis,to come to Asia Categories of the exact rate,and in the final discussion of the causes of error.
