Definition of the features has been conducted aligned with the aforesaid expectations. The constructed feature list comprises three data attributes: points’ coordinates, points’ difference to the excised cylinder (both Euclidean and polar) and points’ distance to the excised cylinder as quantitative continuous, tumor size and breast density with categorical ordinal, and breast laterality and tumor region with categorical nominal attribute. The point coordinates simply expresses the location of each point in the 3D coordinate system, while the point coordinates difference feature reflects the difference between healthy points and the excised cylinder in each axis of the coordinate system. While the distance to the excised cylinder highlights the Euclidean distance from each healthy point, the polar distance to the excised cylinder expresses the same distance, but in polar notation. It is important to note that the coordinate difference and distance features for damaged points (inside the excised cylinder) are considered to be zero.
