The workflow reads input data from a CSV file using the Read CSV node and loads a pre-trained clustering model using the H2O ML Model Load node. The H2O Score node applies the loaded KMeans model to assign cluster labels to the input data. The scored results are previewed using the Print N Rows node, clustering quality is assessed using the H2O Clustering Evaluator node, and related metrics are captured using the ML Data Metrics node for further analysis.
