“…We see that the most common experimental design to test MGR systems is Classify. More than 91% (397) 2 of the referenced work having an experimental component (435) uses such a design [1-9, 11- 21, 26-43, 45,47-50,52-56,58-60,62-65,68-70,72-76,79-83,86-90,92-99,102-106,108-122, 124-135, 137-148, 150, 151, 153-165, 167-172, 174-180, 182-197, 199-202, 204- [271] test a neural network trained to discriminate between classical and pop music. They extract features from the audio, input them to the neural network, and compare the output labels against those they assigned to the excerpts of their dataset.…”
