Graph-based clustering algorithm
WebPopularized by its use in Seurat, graph-based clustering is a flexible and scalable technique for clustering large scRNA-seq datasets. We first build a graph where each node is a cell that is connected to its nearest neighbors in the high-dimensional space. Webthe L2-norm, which yield two new graph-based clus-tering objectives. We derive optimization algorithms to solve these objectives. Experimental results on syn-thetic datasets and real-world benchmark datasets ex-hibit the effectiveness of this new graph-based cluster-ing method.
