We used SciPy’s (Virtanen et al. 2024) implementation. Perhaps, the most important benefit is that we do not have to perform repeated AE training in order to find the optimal latent AE dimension. ... of a low-rank matrix Z (Stewart 1998): where E is a Gaussian noise matrix. The matrix Z is also called ...
Web21 Oct 2013 · For a Bessel filter, this is defined as the point at which the asymptotes of the response are the same as a Butterworth filter of the same order. For digital filters, Wn is normalized from 0 to 1, where 1 is the Nyquist frequency, pi radians/sample. ( Wn is thus in half-cycles / sample.) For analog filters, Wn is an angular frequency (e.g. rad/s).
