my current research consists of:
Unbiased mixed variables distance (van de Velden, M., Iodice D’Enza, A., Markos, A. and Cavicchia, C.) - Under review - arXiv - SSRN
An Exact Solution Approach for Hierarchical Clustering (Willemsen, R., Cavicchia, C., van den Heuvel, W. and van de Velden, M.) - Revision submitted
Ultrametric Factor Analysis for building hierarchies of reliable and unidimensional latent concepts (Bottazzi Schenone, M., Cavicchia, C., Vichi, M. and Zaccaria, G.) - Revision submitted
Convex Clustering of Mixed Numerical and Categorical Data (Brink, T. and Cavicchia, C.)
Sparse Scaling (Groenen, P.J.F. and Cavicchia, C.)
KNN for mixed data (van de Velden, M., Iodice D’Enza, A., Markos, A. and Cavicchia, C.)
Clustering combining two sources of information: dissimilarities and features on the same observations (Cavicchia, C., van de Velden, M. and Vichi, M.)
Higher-order Factor Analysis (Cavicchia, C. and Vichi, M.)
Model-based Parsimonious Hierarchical Clustering (Cavicchia, C., and Scrucca, L.)
