abstract={This thesis explores the possibility of calculating the permeability of materials
with regression based of classification software instead of using famous

materials. The chosen model is based on classification from support vector
machines. This classification algorithm was chosen because support vector
machines have a history of showing accuracy comparable to those of other

base. The thesis consists of a theoretical part and an applied one,

explains how certain parameters are calculated and used for the classification
algorithm to perform well. It is shown that the classification algorithm
surpasses the famous Kozeny-Carman equation in terms of accuracy of the
calculations for fibre structures. It is also shown that it suffices to extract
parameters from two dimensional images of the three dimensional structures
to gain equal precision as if the whole three dimensional structure is taken
into account. This raises hope that microscopy images can be used to calculate
the permeability of materials. Finally it is shown that the content
of the training set is more important than its size for the support vector
machine to perform well.},
