In this paper, a computational approach has been implemented which is based on spectral clustering with fuzzy C -means algorithm to find different types of amino acid sequences from the binding region between ABC transporter and membrane cholesterol. Finally from our experiment, we achieved better ...
谱聚类(spectral clustering)是广泛使用的聚类算法,比起传统的K-Means算法,谱聚类对数据分布的适应性更强,聚类效果也很优秀,同时聚类的计算量也小很多,更加难能可贵的是实现起来也不复杂。在处理实际的聚类问题时,个人认为谱聚类是应该首先考虑的几种算法之一。下面我们就对谱聚类的算法原理做一个总结。 1. 谱聚类...

As any learning algorithm the clustering also depends on the data bias and could lead to misinformation or misinterpretation of results obtained from our model. However we believe our method and clustering in general to be of interest for future years as it would reduce the need of heavy data ...

First, considering both geographic location information of shared bike stations and the migration trend of bikes between stations, we design a two-level fuzzy c-means clustering algorithm to cluster shared bicycle stations into groups, which can better capture the connection between shared bicycle ...
