Study of the Couple (Reflection Coefficient, K-Nn Rule)
Some sets of parameters, obtained from a one-to-one transformation from AR ones, have successfully been used in Spectral Analysis and Classification. In a previous paper El], a statistical analysis of the cepstral coefficient probability density function (p.d.f.) revealed why, in many cases, the k-NN rule is a necessary tool in this particular representation space. The aim of this paper is to study a further set of parameters : the reflection coefficients.
