Abstract
Medical data is particularly interesting as a subject for relational
data mining due to the complex interactions which exist between
different entities. Furthermore, the ambiguity of medical imaging
causes interpretation to be complex and error-prone, and thus
particularly amenable to improvement through automated decision
support. Probabilistic Inductive Logic Programming (PILP) is a
particularly well-suited tool for this task, since it makes it
possible to combine the relational nature of this field with the
ambiguity inherent to human interpretation of medical imaging. This
work presents a PILP setting for breast cancer data, where several
clinical and demographic variables were collected retrospectively, and
new probabilistic variables and rules reflecting domain knowledge were
introduced. Experiments show that the probabilistic model produced can
not only match the predictions of a team of experts in the area, but
also produce meaningful rules which output better calibrated
probability values.
