Mean shift clustering example

WebAug 20, 2024 · Mean Shift. Mean shift clustering involves finding and adapting centroids based on the density of examples in the feature space. We prove for discrete data the convergence of a recursive mean shift procedure to the nearest stationary point of the underlying density function and thus its utility in detecting the modes of the density.
