Webb1 mars 2024 · Some of the top down clustering techniques are FINDIT (a Fast and Intelligent Subspace Clustering Algorithm using Dimension Voting) (Woo et al., 2004), PROCLUS (PROjected CLUStering) (Aggarwal et al., 1999) and ORCLUS (arbitrarily ORiented projected CLUSter generation) (Aggarwal and Yu, 2000). Webbcombined algorithms are tested using synthetic datasets. The Proclus algorithm is modified at a specific point where the density based algorithm is implemented. Findings: The results of the proposed algorithm are found to contain more clusters than mere Proclus algorithm does. The results is as such because in Proclus clustering the data …
