WebDec 25, 2024 · Now the data I would get would be text and unlabeled. My approach to this problem would be as following:-. 1.) Label the data using clustering algorithms like DBScan, HDBScan or KMeans. The number of clusters would obviously be 3. 2.) Train a Classification algorithm on the labelled data. Now I have never performed clustering on … WebHierarchical clustering is an unsupervised learning method for clustering data points. The algorithm builds clusters by measuring the dissimilarities between data. Unsupervised learning means that a model does not have to be trained, and we do not need a "target" variable. This method can be used on any data to visualize and interpret the ...
