I was able to get it to work using a distance matrix: Error: cluster = AgglomerativeClustering(n_clusters = 10, affinity = "cosine", linkage = "average") cluster.fit(similarity) Works: cluster_dist = AgglomerativeClustering(distance_threshold=0, n_clusters=None) cluster_dist.fit(distance)...
It starts from a numeric matrix, compute the similarity between each pair of item thanks to the linkage() function and plot the result with the dendrogram() function. Most basic dendrogram and clustering with Python and Matplotlib The next post explains how to customize the output: change node...
the dendrogram is built up via a step by step elimination of the similarity matrix. In the computer software, each elimination is recorded as a transformation of the matrix. At the end, the random pattern of SCs in the original similarity matrix is changed. Due to the algorithm, clusters of...
