LloydMaxalgoritmiä
LloydMaxalgoritmiä, often referred to as Lloyd's algorithm or the generalized Lloyd algorithm, is a foundational iterative procedure used in data compression and cluster analysis. Its primary purpose is to find an optimal set of centroids for a given set of data points, minimizing the expected distortion. The algorithm is particularly associated with vector quantization, where it is used to determine the codebook vectors.
The core of Lloyd's algorithm operates in two distinct steps. First, it assigns each data point to
While highly effective, Lloyd's algorithm is sensitive to the initial placement of centroids and can converge
