I have a softspot for signal processing, so the appearance of spectrogram fingerprinting — using non-negative matrix factorization and a hidden Markov model — was pleasing. (This is a similar technique to how Shazam fingerprints songs for very rapid retrieval.)

This is nice too... http://esd1.lbl.gov/research/projects/- induced seismicity/egs/geysers.html

Not seeing any code anywhere though
