Detected classes and extracted useful information by method \(\mathcal {M}\). a Noisy spectrogram of signal f(t)=f1(t)+f2(t)+f3(t) in reference to Eq. (24). b RSD (contours). c–o classes extracted by method \(\mathcal {M}\). p Extracted useful information RI. Parameters given by MDL functional minimization are Γ=0.7,K = 11
