“…Data mining techniques focus on studying algorithms to find implicit, previously unknown, and potentially useful information from data. In the context of medical care existing data mining approaches encompass different analyses, such as mining underlying associations among data items (e.g., [6,20,34,38,40]), clustering (e.g., [4,5,48]), and classification (e.g., [26,33]). However, the increasing complexity and heterogeneity of medical data prompts the need for novel and effective approaches to automatically mining actionable knowledge.…”
