abstract = "We propose a method of knowledge reuse for an ensemble
of genetic programming-based learners solving a visual
learning task. First, we introduce a visual learning
method that uses genetic programming individuals to
represent hypotheses. Individuals-hypotheses process
image representation composed of visual primitives
derived from the training images that contain objects
to be recognised. The process of recognition is
generative, i.e., an individual is supposed to restore
the shape of the processed object by drawing its
reproduction on a separate canvas. This canonical
method is extended with a knowledge reuse mechanism
that allows a learner to import genetic material from
hypotheses that evolved for the other decision classes
(object classes). We compare the performance of the
extended approach to the basic method on a real-world
tasks of handwritten character recognition, and
conclude that knowledge reuse leads to significant
convergence speedup and, more importantly,
significantly reduces the risk of overfitting.",
