In our research, the integer values of the BIRADS and margin attributes were normalized by their maximum values of 5, resulting in attribute values ranging from 0.2 to 1. The integer values of the shape and density attributes were normalized by their maximum values of 4, resulting in attribute values ranging from 0.25 to 1. The age attribute integer value was normalized by 100. The severity attribute was a binary value of either 0 or 1, representing benign or malignant diagnoses, respectively.
