abstract = "Transfer learning has been considered a key solution
for the problem of learning when there is a lack of
knowledge in some target domains. Its idea is to
benefit from the learning on different (but related in
some way) domains that have adequate knowledge and
transfer what can improve the learning in the target
domains. Although incompleteness is one of the main
causes of knowledge shortage in many machine learning
real-world tasks, it has received a little effort to be
addressed by transfer learning. In particular, to the
best of our knowledge, there is no single study to use
transfer learning for the symbolic regression task when
the underlying data are incomplete. The current work
addresses this point by presenting a transfer learning
method for symbolic regression on data with high ratios
of missing values. A multi-tree genetic programming
algorithm based feature-based transformation is
proposed for transferring data from a complete source
domain to a different, incomplete target domain. The
experimental work has been conducted on real-world data
sets considering different transfer learning scenarios
each is determined based on three factors: missingness
ratio, domain difference, and task similarity. In most
cases, the proposed method achieved positive
transductive transfer learning in both homogeneous and
heterogeneous domains. Moreover, even with less
significant success, the obtained results show the
applicability of the proposed approach for inductive
transfer learning.",
