摘要: 针对多数已有的计算方法无法同时预测抗菌肽的多种功能类型的问题,提出一种基于伪氨基酸组成和多标记最近邻算法的抗菌肽功能类型预测的系统方法:采用伪氨基酸组成抽取抗菌肽序列的特征向量,并且引入多标记最近邻算法作为预测引擎,同时预测抗菌肽的多种功能类型.实验结果表明,本方法显著地提高了预测性能,为该领域的进一步研究提供了一个有用的工具.Abstract: In order to solve the problem that most of the existing computational methods can only predict one functional type of antibacterial peptides, a computational prediction method was developed for prediction of multiple functional types of antibacterial peptides based on the pseudo amino acid composition(PseAAC) and multi-label k-nearest neighbor(MLkNN) algorithm.It used the PseAAC to extract feature vector of antimicrobial peptide sequence, introduced the MLkNN algorithm as the prediction engine, and predicted a variety function type of antibacterial peptides simultaneously.Experimental results showed that the proposed method significantly improved the prediction performance, and it provided a useful tool for the further research in this field.
