Python for Machine Learning - The Complete Beginners Course - Use Cases

The video tutorial introduces clustering, a technique used to group similar data. It highlights various applications such as data analysis, noise detection, and duplicate detection. The tutorial also previews upcoming lectures on clustering algorithms, including K-means, hierarchical, and density-based clustering.

• Density-based clustering

• Hierarchical clustering

• K-means clustering

What type of clustering algorithm builds a tree of clusters?

• Spectral clustering

• Density-based clustering

• Hierarchical clustering

• K-means clustering

Which clustering method is particularly useful for finding clusters of varying densities?
