| The aim of MCRDR is to preserve the advantages and essential strategy of RDR in dealing with multiple independent classifications. MCRDR, like RDR, is based on the assumption that the knowledge an expert provides is essentially a justification for a conclusion in a particular context. A major component of the context is the case which has been given a wrong classification and how this differs from other cases for which the classification is correct. As we shall see, the context in MCRDR is preserved differently and only includes rules that have been satisfied by the data and validation extends to differentiating the new case from a range of different cases. Below figure show the MCRDR process model. We will discuss each phase more detail in the following sections.
