Clustering healthcare processes with a robust approach Clustering healthcare processes with a robust approach Πλήρης Δημοσίευση σε Συνέδριο Conference Full Paper 2015-11-042013enProcess Mining has been proved to be an effective approach to discover process models from event logs. However, when a highly diversified behavior is allowed (like in a healthcare environment) mining a single model could yield pointless results. One way to tackle this diversity is clustering the log into coherent groups. In this work we propose a robust spectral clustering approach. The spectral approach let one with greater flexibility in representing data (a similarity measure is enough) while the proposed robust technique can handle outliers, a common occurrence in healthcare processes. http://creativecommons.org/licenses/by/4.0/26th European Conference on Operational Research Matsatsinis Nikolaos Ματσατσινης Νικολαος Doumpos, Michael Grigoroudis, Evangelos Panagiotis Manolitzas Pavlos Delias
