K-means clustering is one of the simplest unsupervised learning algorithms, which is used to solve the clustering problems. A heuristic device is used when an entity X exists to enable understanding of, or knowledge concerning, some other entity Y.. A good example is a model that, as it is never identical with what it models, is a heuristic device to enable understanding of what it models.Stories, metaphors, etc., can also be termed heuristic in this sense. And the main characteristic of DD is for the description of the cluster center, which is shown as follows: Distance-based Pareto GA * Reference: G. Rudolph, Convergence of evolutionary algorithms in general search spaces, In Proceedings of the Third IEEE conference of Evolutionary Computation, 1996, p.50-54. For example, our algorithms might decide that a business that's farther away from your location is more likely to have what you're looking for than a business that's closer, and therefore rank it higher in local results.
