Mean Shift Clustering

What is Mean Shift Clustering?

Mean Shift Clustering is a non-parametric, unsupervised machine learning technique used for clustering data points based on their density. It is particularly suited for applications where the number of clusters is not known beforehand, and the data may contain irregular shapes or noise.

How does Mean Shift Clustering work?

Mean Shift Clustering works by placing a circular window around each data point, calculating the mean of the data points within the window, and shifting the window center to the mean. This process is repeated iteratively until the window centers converge to the centroids of the dense regions in the data. The data points are then assigned to clusters based on their proximity to the centroids.

Benefits of Mean Shift Clustering

  • No assumption of cluster shape: Mean Shift Clustering does not make any assumptions about the shape or size of clusters, making it suitable for data with irregularly shaped clusters.
  • Robust to noise: The technique is less sensitive to noise in the data, as it relies on the density of data points rather than distance metrics.
  • Automatic determination of the number of clusters: Unlike some other clustering algorithms, Mean Shift Clustering does not require the number of clusters to be specified beforehand, as it can discover the appropriate number based on the data density.
