Embodiment Construction
[0052] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.
[0053] Aiming at the model selection problem existing in the existing discriminant clustering algorithm, the present invention proposes a method of using normalized information measure as the objective function, so that the algorithm has the ability of automatic model selection, thereby improving the algorithm's unreasonable initial model order artificially selected. The ability to obtain better clustering results under certain circumstances.
[0054] Data clustering is to divide the collection of data objects into multiple different classes or clusters. The similarity between data objects in each cluster is higher than that of objects in other clusters. In text processing, customer group grouping And image segmentation a...
