#18 Question: Shift-invariance for classification

Dear waveleteers,
Recently, I have been applying Saito's Local Discriminant Basis
algorithm to the classification of underwater, acoustic, transient
data. Being transient, I find that great care needs to be taken to
avoid/minimise translations when combining the training data of each
class into the time-frequency energy maps. Having looked at Cohen et
al's algorithm for Orthogonal Shift-invariant wavelet packet
decomposition, I am interested in incorporating this. My question is,
what cost function should I use for determining the 'best',
shift-invariant wavelet packet tree for each time-series ? Any
comments on this, are greatly appreciated,

Susan Godfrey.
