‘false’ zero count observations. Here, we have developed scDeepCluster, a single-cell model-based deep embedded clustering method, which simultaneously learns feature representation and clustering via explicit modelling of scRNA-seq data generation. Based on testing extensive simulated data and real ...
Iterative clustering: After cluster initialization, we improve the clustering using an unsupervised algorithm that alternates between two steps until convergence. In the first step, we compute a soft assignment of each cell between the embedded points and the cluster centroids. Following van der Maaten...
Clustering, an unsupervised learning approach, is a good fit to address this task. Typically, a clustering algorithm aims at identifying clusters, by minimizing dissimilarity within a given cluster while maximizing that between clusters. The well-established single-cell pipelines, such as Seurat [2]...
