Mean-Shift
Mean Shift is a powerful clustering algorithm used in unsupervised machine learning to identify dense regions within a dataset. Unlike traditional methods like K-Means, it does not require prior knowledge of the number of clusters, making it versatile for various applications. The algorithm operates by defining a window around data points and iteratively shifting this window towards areas of higher data density until convergence is achieved. This approach allows Mean Shift to effectively discover clusters of varying shapes and sizes, making it suitable for tasks such as image segmentation and object tracking in computer vision.
