VSGETAWAY描述子
5) SVRDF
SVRDF描述子
1.
To establish a new amino acid structure descriptor that can be applied to polypeptide quantitative structure activity relationship (QSAR) studies, a new descriptor, SVRDF, was derived from a principal components analysis of a matrix of 150 radial distribution function index of amino acids.
研究结果表明,SVRDF描述子能够系统地表征肽与生物活性相关的结构信息,有望成为多肽定量构效关系研究中一种有效的结构表征方法。
6) V-system descriptor
V描述子
1.
In this paper,we present a novel V-system descriptor for 2D models;the descriptor is invariant against the rotation,translation,scale transform,and can remove the effect of the arbitrary start point of the shape through the principal orientation.
提出了一类新的V描述子,对二维图形进行V变换提取形状信息,并定义归一化后的变换系数为描述子,其具有旋转、平移、缩放不变性,通过形状主方向在一定程度上消除了起始点的影响。
