Distance Metrics and Clustering Methods for Mixed-type Data
Abstract
In spite of the abundance of clustering techniques and algorithms, clustering mixed interval (continuous) and categorical (nominal and/or ordinal) scale data remain a challenging problem. In order to identify the most effective approaches for clustering mixed–type data, we use both theoretical and empirical analyses to present a critical review of the strengths and weaknesses of the methods identified in the literature. Here, the guidelines on approaches to use under different scenarios are provided, along with potential directions for future research.

Figure 1: Simulation results: performance of k-modes clustering and latent class analysis (LCA) for various quantile splits of the data. A mixed-type data set was generated with two underlying clusters, and the interval scale variable was discretised using a quantile split with the number of bins shown along the x-axis.more »
