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.
