Differential Diagnosis of Erythmato-Squamous Diseases Using Classification and Regression Tree.

INTRODUCTION: Differential diagnosis of Erythmato-Squamous Diseases (ESD) is a major challenge in the field of dermatology. The ESD diseases are placed into six different classes. Data mining is the process for detection of hidden patterns. In the case of ESD, data mining help us to predict the diseases. Different algorithms were developed for this purpose.

OBJECTIVE: we aimed to use the Classification and Regression Tree (CART) to predict differential diagnosis of ESD.

METHODS: we used the Cross Industry Standard Process for Data Mining (CRISP-DM) methodology. For this purpose, the dermatology data set from machine learning repository, UCI was obtained. The Clementine 12.0 software from IBM Company was used for modelling. In order to evaluation of the model we calculate the accuracy, sensitivity and specificity of the model.

RESULTS: The proposed model had an accuracy of 94.84% (.

STANDARD DEVIATION: 24.42) in order to correct prediction of the ESD disease.

CONCLUSIONS: Results indicated that using of this classifier could be useful. But, it would be strongly recommended that the combination of machine learning methods could be more useful in terms of prediction of ESD.
