Hierarchical Clustering and Heatmap

Last edited: 

This component performs hierarchical clustering on numeric input data. The results are displayed in a composite interactive view containing a dendrogram and a heatmap. The rows of the heatmap are sorted by the associated clusters. The dendrogram view can be used to change the number of clusters. Required extensions: KNIME JavaScript Views (Labs) https://hub.knime.com/knime/extensions/org.knime.features.js.views.labs/latest
