[Corpora-List] Wavelet for NLP

[Stefan Evert]

I'm not an expert on signal processing, but are you sure this is  
really a wavelet transformation? It looks more like a sort of time- 
frequency analysis (which does give a nice visualisation!), while  
wavelet transforms are supposed to be bijective.  Can you reconstruct  
the original signal from the time-frequency distribution?

Best wishes,
Stefan
