In this work we propose a novel unsupervised classification technique 5 based on the estimation of nonlinear nonparametric mixed-effects models. The proposed method is an iterative algorithm that alternates a nonparametric EM step and a nonlinear Maximum Likelihood step.We apply this new procedure to perform an unsupervised clustering of longitudinal data in two different case studies.

Abstract
In this work we propose a novel unsupervised classification technique 5 based on the estimation of nonlinear nonparametric mixed-effects models. The proposed method is an iterative algorithm that alternates a nonparametric EM step and a nonlinear Maximum Likelihood step.We apply this new procedure to perform an unsupervised clustering of longitudinal data in two different case studies.
