Statistical Discrimination

Abstract

A new and larger learning ensemble was assembled to better represent the area under study and to better represent the two classes of events statistically. The effectiveness of various short-period statistics for discrimination was studied. Higher-order surface modes were sought in two-long- period spectral peaks measured over short- Higher-order surface modes were sought in two long-period events by obtaining estimates of group velocity from maximum-entropy spectral peaks measured over short time gates of the seismogram. Definition of the fundamental Rayleigh mode was good, and possible higher-mode energy was indicated. Matched filtering was performed on a suite of long-period explosion recordings. Chirp filters worked almost as well as master events.
