Abstract
This paper aims at formalizing the concept of learning rules from
multisource data in a cardiac monitoring context. Our method has been
implemented and evaluated on learning from data describing cardiac
behaviors from different viewpoints, here electrocardiograms and
arterial blood pressure measures. In order to cope with the
dimensionality problems of multisource learning, we propose an
Inductive Logic Programming method using a two-step strategy.
Firstly, rules are learned independently from each sources. Secondly,
the learned rules are used to bias a new learning process from the
aggregated data. The results show that the the proposed method is much
more efficient than learning directly from the aggregated data.
Furthermore, it yields rules having better or equal
accuracy than rules obtained by monosource learning.
