Analysis of Medical Treatments Using Data Mining Techniques

Xin Xiao, Silvia Chiusano
2014 The IEEE intelligent informatics bulletin  
The clustering approach is named multiple-level because we apply the clustering algorithm in a multiple-level fashion, by focusing on different dataset portions and locally identifying groups of patients  ...  For example, data collections on patient treatments are usually characterized by an inherent sparseness and variable distribution, due to the large variety of possible treatments performed by patients  ...  This model can be used to automatically assign a new patient to a given class based on her/his profile and examination history.  ...
