**DBSCAN** (Density-Based Spatial Clustering of Applications with Noise) offers a powerful alternative to traditional clustering algorithms like K-means and hierarchical clustering, especially when dealing with **clusters of arbitrary shapes** and **datasets containing noise**. 

The table above highlights the key advantages of DBSCAN: its ability to find clusters of **any shape**, its robustness to **noise**, and its **automatic determination** of the number of clusters. 
 

Therefore, DBSCAN is particularly well-suited for scenarios where:

- Clusters have irregular shapes; 

- Noise points are present and need to be identified; 

- The number of clusters is not known beforehand; 

- Data density varies across the dataset.
