Abstract

Manifold Learning has attracted much attention for this decade. One of the main features of Manifold Learning is that Manifold Learning tries to conserve local topologies in high-dimensional space. In this paper, we discuss the effect of the dimensionality reduction of input spaces of Evolutionary Learning. We examine two Manifold Learning algorithms: Isomap and LLE. We adopt the Instance-Based Policy Optimization as an Evolutionary Learner. In addition, we introduce a metric of relative error of distances between original input space and reduced space. We will show the relationship between this metric and the number of neighbors in Manifold Learning.
