One drawback on the use of Support Vector Machines (SVM) in real
applications is its slow classification speed, proportional to the
product of number of features and number of support vectors. Feature
Subset Selection (FSS) is one way for reducing the dimensionality,
normally reducing the number of support vectors, and consequently the
recognition time. However, for the multiclass SVM, applying FSS in the
whole input space does not achieve an optimal feature subset for each
independent binary classifier. This work proposes a new structure, in
which the FSS is performed independently for each SVM. The experiments
with real world data showed a much higher average dimensionality
reduction, decreasing the recognition time by several orders with a
comparable performance with the full features set. |
