We investigated the geometrical complexity of several high-dimensional, small sample classication problems and its changes due to two popular feature selection procedures, forward feature selection (FFS) and Linear Programming Support Vector Machine (LPSVM). We found that both pro-cedures are able to transform the problems to spaces of very low dimensionality where class separability is improved over that in the original space. The study shows that geo-metrical complexities have good potentials for comparing different feature selection methods in aspects relevant to classication accuracy, yet independent of particular clas-sier choices. 1
