Music in Our Ears: The Biological Bases of Musical Timbre Perception
Figure 5
The average KL divergence between support vectors of instruments belonging to different broad classes.
Each panel depicts the values of the 3 dimensional average distances between pairs of instruments of a given couple of classes: (A) wind vs. percussion; (B) string vs. percussion; (C) wind vs. string. The 3 dimensional vectors are displayed along eigenrates (x-axis), eigenscales (y-axis) and eigenfrequency (across small subpanels). Red indicates high values of KL divergence and blue indicates low values.
