GENERALIZED PHI-DIVERGENCES AND EM-ALGORITHM IN ACOUSTIC EMISSION
Original language description
We deal with a simple method of construction of phi-divergences using a normalization of convex or concave functions. First we mention the well-known divergences (Kullback, Hellinger, chi^2, Power, ...) and then we introduce several of its modifications.As an example, we present generalized LeCam and Hellinger divergences. These new families of divergences open new research possibilities in the area of statistical treatment of acoustic emission sources. Further, we deal with the classification of acoustic emission signals by means of distribution mixtures (DM). The acoustic signals are separated by means of suitable parameters obtained directly from the signals and from the normed frequency spectra. The very phi-divergence distance measure is employedas the additional signal spectrum attribute. We are concerned with the efficient set of classification parameters and we test the proposed classification method for the case of laboratory data and also for the experimental design.
