The coefficients are kept invariant over a block of symbols.
The low-low frequency band coefficients are kept in memory, and they will be used in the inverse extraction process.
Several scenarios are compared, while three PID controllers' coefficients are kept constant for all the tests: The separator pressure, water level, and hydrocyclone pressure-drop-ratio (PDR) controllers.
Coefficients are kept for the final computation when the threshold is reached on ((e_x), (h_x), and (h_y)) or ((e_y), (h_x), and (h_y)).
On average, for a cover image with the size of 512×512, 0.63% of the coefficients are kept to compute the test; 0.64% of the coefficients from a stego image are used.
The normalized static log-spectral features and the dynamic features are transformed into PROSPECT features with D c = 4, i.e., for each stream in the features, four cepstral coefficients are kept, and D = 22 projection coefficients are appended.
But only 12 of the 26 DCT coefficients are kept because the higher DCT coefficients represent fast changes in the filter bank energies which reduce the performance of system.
Here, the channel coefficients are kept constant during two-symbol period and each channel has L = 4 transmission paths of equal weight, i.e., |pj,l|2 = 1/L, l = 0, 1, 2, 3.
The classification model with the best Matthew's Correlation Coefficients is kept for the comparison study.
If only the largest M φ wavelet coefficients are kept, which contain most of the relevant information, then the dimensions of the vectorised compressed data ỹ are reduced to M s × M φ.
