Optics density based clustering

WebDensity-Based Clustering refers to one of the most popular unsupervised learning methodologies used in model building and machine learning algorithms. The data points … WebMar 15, 2024 · It is able to identify text clusters under the sparsity of feature points derived from the characters. For the localization of structured regions, the cluster with high feature density is calculated and serves as a candidate for region expansion. An iterative adjustment is then performed to enlarge the ROI for complete text coverage.
