Analyze Data by Training a k-Means Clustering on Location Data

In this workflow, we perform a Clustering task on location data where we have longitude and latitude information. We use the k-means algorithm to cluster this data and then visualize the clustering results.






Clustering: k-Means Read Data - The data contains various attributesabout the house and the house price Transform: - Filter the data - Normalize the data Evaluation Apply and score Model How to train Clustering Model? Step 1: Drag the k-Means node and double click to open the dialog Step 2: Select the "Number of clusters" as 3. In the "ColumnSelection"select the Columns "Lat" and "Long"Step 3: RIght Click on the node and select "Execute " to performclustering How to evaluate Clustering Model? Step 1: To visualize the clusters drag the Scatter Plot nodeand the OSM Map View. These nodes should be connectedto Color Manager to viulaize clusters with colors Step 2: To evaluate the clustering task, connect the clusteringoutput to "Silhouette Coefficient" node. Select the "ClusteringColumn Selection" as "Cluster"Step 3: Execute the node to get Silhouette Coefficients foreach instance, each cluster and for overall clustering task In CaliforniaVisualize the clusterson world mapColor accordingto clusterClusteringk=3Visualize the clustersEvaluate ClusterPerformance (higher value is preferred)Locations_dataStandardizethe dataDenormalize datato original values Row Filter OSM Map View Color Manager k-Means Scatter Plot SilhouetteCoefficient Table Reader Normalizer Denormalizer Clustering: k-Means Read Data - The data contains various attributesabout the house and the house price Transform: - Filter the data - Normalize the data Evaluation Apply and score Model How to train Clustering Model?
