Continuous state Gaus-sian dynamical models, such as linear dynamical systems (LDSs), have long been studied [12], and recently rich models of continu-ous dynamics have been extended to the NMF family using gamma-distributed models [6,7] in models known as non-negativedynamical systems (NDSs). There have also been combinations with discrete

• Discrete Fourier Transform would normally require O(n2) time to process for n samples: • Don’t usually calculate it this way in practice. • Fast Fourier Transform takes O(n log(n)) time. • Most common algorithm is the Cooley-Tukey Algorithm.

NOTES: 1) The frequency domain and time domain are alternative representations of exactly the same signals. Conversion between the two is information preserving.

data-overfitting, Bone et al. presented a vocal arousal scoring method (VC-AS) that incorporates a minimal set of knowledge-inspired vocal features into an unsupervised (rule-based) system design [10]. The framework is interpretable, scale-continuous (as opposed to usual discrete n-class arousal states), and oper-

Johnston (1999) recently studied the effects of 36 practice sessions on dual-task interference. Using a PRP design with a Task 1 vocal response and a Task 2 manual response, they found that practice drastically reduced dual-task interference. On the other hand, a small residual PRP effect did remain. The pattern of factor inter-

Signals are distinguished by their domain and the type of value that they take. If a signal f(t) is de ned on (a subinterval of) the real numbers and takes values in the real numbers, then f(t) is called a continuous real-valued signal. The notation f(t) : D !R, where D R, means that f(t) is a continuous real-valued signal.
