Results of kernel PCA with normalized pre-imaging (kPCA), PI with SNR-dependent setting of the kernel variance (PIcSNR), the generalized subspace method (Subspace), spectral subtraction (SpecSub), and the MMSE log-spectral amplitude estimator (LogMMSE) in terms of the PESQ measure on the test set of the airbone database corrupted by AWGN.
