基于改进加权聚类算法的小麦种质推荐模型
Wheat germplasm recommendation model based on improved weighted clustering algorithm
摘要
Abstract
With growing wheat germplasm resources data,how to help breeding experts to obtain wheat germplasm efficiently and ac-curately has become an urgent issue.For this problem,a clustering algorithm-based wheat germplasm recommendation model was pro-posed.Wheat germplasm dataset was clustered using K-means to identify cluster centers of dataset.Cluster group was found to which breeding experts'germplasm data belonged,and then the nearest neighbor algorithm was used to derive wheat germplasm required by ex-perts.Considering different contributions degree of wheat germplasm attribute features,gray weighted K-means clustering algorithm(GWK-means)was proposed.When calculating similarity of wheat germplasm by Euclidean distance,weight of wheat germplasm at-tributes were determined by grey correlation analysis,increasing distance between different clusters,improving accuracy and running speed of clustering algorithm,and providing a strong support for recommendation model.Experimental results on wheat germplasm dataset showed that average accuracy of the top 5 recommended wheat germplasm results and germplasm required by breeding experts reached more than 94%.关键词
