abstract = "Genetic programming approaches are moving from
analysing the syntax of individual solutions to look
into their semantics. One of the common definitions of
the semantic space in the context of symbolic
regression is a n-dimensional space, where n
corresponds to the number of training examples. In
problems where this number is high, the search process
can became harder as the number of dimensions increase.
Geometric semantic genetic programming (GSGP) explores
the semantic space by performing geometric semantic
operations, the fitness landscape seen by GSGP is
guaranteed to be conic by construction. Intuitively, a
lower number of dimensions can make search more
feasible in this scenario, decreasing the chances of
data overfitting and reducing the number of evaluations
required to find a suitable solution. This paper
proposes two approaches for dimensionality reduction in
GSGP: (i) to apply current instance selection methods
as a pre-process step before training points are given
to GSGP; (ii) to incorporate instance selection to the
evolution of GSGP. Experiments in 15 datasets show that
GSGP performance is improved by using instance
reduction during the evolution.",
