Simultaneous unsupervised and supervised classification modeling for clustering, model selection and dimensionality reduction

In the unsupervised classification field, the choice of the number of clusters and the lack of assessment and interpretability of the final partition by means of inferential tools denotes an important limitation that could negatively influence the reliability of the final results. In this work, we propose to combine unsupervised classification with supervised methods in order to enhance the assessment and interpretation of the obtained partition, to identify the correct number of clusters and to select the variables that better contribute to define the groups structure in the data. An application on real data is presented in order to better clarify the utility of the proposed approach.
