This shouldn't be a big surprise, considering how close to the estimated
entropy of various sources current compression algorithms get. In essence,
compressors are statistical learners, and classification problems can be
formulated as partitionings based on statistical similarity. I just wonder
if the overhead of doing a significant number of compression runs against
known sources isn't a bit expensive compared to current methods of
identification.
