Table 4 Analysis of the statistical significance of the percussive/harmonic SDR-SIR-SAR results

From: Percussive/harmonic sound separation by non-negative matrix factorization with smoothness/sparseness constraints

  Percussive Harmonic
  SDR SIR SAR SDR SIR SAR
HPSS <10−8 0.2 <10−11 <10−9 0.9 <10−14
MFS 0.2 <10−3 0.8 0.1 <4·10−2 <10−6
NMPCF <10−7 <10−4 <10−7 <10−6 <10−4 <10−5
  1. Comparing the developed method with the three state-of-the-art separation methods using a one-sided paired t test in the database T1. Each cell show the parameter p that represents the probability of setting a statistically significant result. Considering a confidence interval of 95%, small values of p < 0.05 indicate that there exists statistical significance of the results evaluated.
