Comparison of k-medoids and DB scan

K-medoids:

  1. Cluster Shape:
    • Can handle clusters of arbitrary shapes.
  2. Outlier Handling:
    • Less sensitive to outliers due to medoid calculation.
  3. Density Sensitivity:
    • Not explicitly density-sensitive.
  4. Parameter Dependency:
    • Sensitive to the number of clusters (K) and initial medoids.
  5. Use Cases:
    • Effective for datasets with irregularly shaped clusters.
  6. Computational Efficiency:
    • Can be more computationally expensive, especially for large datasets.

DBSCAN:

  1. Cluster Shape:
    • Can find clusters of arbitrary shapes.
  2. Outlier Handling:
    • Robust to outliers due to density-based approach.
  3. Density Sensitivity:
    • Sensitive to varying cluster densities.
  4. Parameter Dependency:
    • Less dependent on specifying the number of clusters.
  5. Use Cases:
    • Effective for datasets with irregularly shaped clusters and varying densities.
  6. Computational Efficiency:
    • Can be more computationally expensive, especially for large datasets.

Based on the features of your data and the particular objectives of your clustering operation, decide between K-medoids and DBSCAN. DBSCAN is useful for density-sensitive clustering, but K-medoids might be favored due to their resistance to outliers.
