Abstract: Unsupervised classifiers do not require previous training to achieve their task, on the contrary, they are able to propose alternative classifications that make more sense using raw data instead of human interpretation. In this article an unsupervised classifier system using the soft graph colouring model is presented. This model has the ability to deal with risk and the probability of committing Type I or II errors, for instance, in medical diagnosis, where we want to minimise the risk of a mistaken prognosis. The proposed model is evaluated using some classical instances, and the results are compared with other classifiers, given in all cases solutions as good or better than supervised classifiers.
