Python and Java Implementations for Linde-Buzo-Gray / Generalized Lloyd Algorithm
An academic discipline A branch of science An applied science A subfield of computer science A branch of artificial intelligence A subfield of soft computing Branches of machine lea Vector quantization is based on the competitive learning paradigm, so it is closely related to the self-organizing map model and to sparse coding models us It was originally used for data compression.
It is named after Georgy Voronoi, and is also called a Voronoi tessellation, a Voronoi decomposition, a Voronoi partition, or a Dirichlet tessellation after Peter Gustav Lejeune Dirichlet.
Vector quantization VQ is a classical quantization technique from signal processing that allows the modeling of probability density functions by the distribution of prototype vectors. Delaunay triangulation topic A Delaunay triangulation in the plane with circumcircles shown In mathematics and computational geometry, a Delaunay triangulation also known as a Delone triangulation for a given set P of discrete points in a plane is a triangulation DT P such that no point in P is inside the circumcircle of any triangle in DT P.
Example of Lloyd’s algorithm. Member feedback about Voronoi diagram: Optimal code book with 4 vectors; References The original paper describing the algorithm, as an extension to Lloyd’s algorithm: Linde may refer to: The triangulation is named after Boris Delaunay for his work on this topic from This results in a partitioning of the data space into Voronoi cells.

Member feedback about Linde—Buzo—Gray algorithm: Member feedback about Delaunay triangulation: Vector quantization topic Vector quantization VQ is a classical quantization technique from signal processing that allows the modeling of probability density functions by the distribution of prototype vectors.
It is similar to the k-means method in data algoritym. It works by dividing a large set of points vectors into groups having approximately the same number of points closest to them.

Focus Expanding Load 1 level Load 2 levels Load 3 levels. Outline of machine learning topic The following outline is provided as an overview of and topical guide to machine learning.
The difference between the original signal and the reconstructed signal is the quantization error and, in this simple quantization scheme, is a deterministic function of the input signal. Gray in is a vector quantization algorithm to derive a good codebook. In computer science and electrical engineering, Lloyd’s algorithm, also known as Voronoi iteration or relaxation, is an algorithm named after Stuart P.
That set of points called seeds, sites, or generators is specified beforehand, and for each seed there is a corresponding region consisting of all points closer to that seed than to any other. Member feedback about Lloyd’s algorithm: Voronoi diagram topic 20 points and their Voronoi cells larger version below In mathematics, a Voronoi diagram is a partitioning of a plane into regions based zlgorithm distance to points in a specific subset of the plane.
Iteration 1 Iteration 2 Iteration 3 Iteration 15 In the last image, the points are very near the centroids of the Voronoi cells. Optimal code book with 2 vectors; D initial estimation 2: Edit page Delete page.
