abstract = "There is an underlying assumption on most model
building processes: given a learnt classifier, it
should be usable to explain unseen data from the same
given problem. Despite this seemingly reasonable
assumption, when dealing with biological data it tends
to fail; where classifiers built out of data generated
using the same protocols in two different laboratories
can lead to two different, non-interchangeable,
classifiers. There are usually too many uncontrollable
variables in the process of generating data in the lab
and biological variations, and small differences can
lead to very different data distributions, with a
fracture between data. This paper presents a
genetics-based machine learning approach that performs
feature extraction on data from a lab to help increase
the classification performance of an existing
classifier that was built using the data from a
different laboratory which uses the same protocols,
while learning about the shape of the fractures between
data that motivated the bad behaviour.
The experimental analysis over benchmark problems together with a real-world problem on prostate cancer diagnosis show the good behavior of the proposed algorithm.",
