Questions & Step-by-Step Solutions

Which evaluation metric is NOT typically used for clustering?
  • Step 1: Understand what clustering is. Clustering is a method of grouping similar items together based on their features.
  • Step 2: Learn about evaluation metrics. Evaluation metrics are used to measure how well a model performs.
  • Step 3: Identify common evaluation metrics for clustering. Common metrics include Silhouette Score, Davies-Bouldin Index, and Adjusted Rand Index.
  • Step 4: Recognize the F1 Score. The F1 Score is a metric used to evaluate classification tasks, which involve predicting categories.
  • Step 5: Conclude that F1 Score is not used for clustering. Since clustering does not involve predefined categories, the F1 Score is not applicable.
