Average (a) ${\mathcal{C}}^{\mathit{SVM},\phi }$ and (b) ${\mathcal{C}}^{C4.5,\phi }$ for φ ∈ {PCA, LDA, MDS, ISO, LLE, LEM}, for 10 binary-class datasets, before feature pruning. Additionally, average (c) ${\mathcal{C}}^{\mathit{SVM},\phi }$ is given for all φ, for 10 binary-class datasets, following feature pruning.
