High dimensional dataset
WebTitle Cluster High Dimensional Categorical Datasets Version 0.3.0 Description Scalable Bayesian clustering of categorical datasets. The package implements a hierarchi-cal Dirichlet (Process) mixture of multinomial distributions. It is thus a probabilistic la-tent class model (LCM) and can be used Web30 mag 2024 · Based on the high dimensionality of such datasets, the use of traditional methods of association rules mining directly applied to these datasets could result in unsatisfactory performance [ 6 ]. To improve performance brought by high-dimensional datasets, multiple specialized algorithms have been proposed in the last decade.
