It does, it just depends on the model. In the 1-bit square wave duty cycle estimator, a message is a "bit". In the English text compression experiment, a message is "a character". In the white noise entropy estimation experiment, a message is a "byte". In the binary waveform entropy experiment, a message is "a string of bits". In the bitflip counter, a message is an event that "two consecutive bits differ" In the parametric squarewave thought experiment, message is "a set of parameteres describing a square wave". Whatever arbitrarily chosen thing I send to you over a channel, becomes a "message". There's no universal definition of what a "message" is, depending on the particular model, it can be literally anything. -- dupswapdrop -- the music-dsp mailing list and website: subscription info, FAQ, source code archive, list archive, book reviews, dsp links http://music.columbia.edu/cmc/music-dsp http://music.columbia.edu/mailman/listinfo/music-dsp
