Optimal number of clusters elbow method
WebApr 14, 2024 · Recent advances in single-cell sequencing techniques have enabled gene expression profiling of individual cells in tissue samples so that it can accelerate biomedical research to develop novel therapeutic methods and effective drugs for complex disease. The typical first step in the downstream analysis pipeline is classifying cell types through … WebNote that the elbow criterion does not choose the optimal number of clusters. It chooses the optimal number of k-means clusters. If you use a different clustering method, it may need a different number of clusters. There is no such thing as the objectively best clustering. Thus, there also is no objectively best number of clusters.
