A Hierarchical Neuronal Model for Generation and Online Recognition of Birdsongs
Figure 12
Recognition results for the fourth simulation ‘Cooling of HVC’, where the format is the same as in Figure 5 with arbitrary units.
Left: We slowed down the singing bird by decreasing the rate constants by 3%: 
, 
and 
. Middle: The rate constants for the recognition are 
, 
and 
. Right: The listening bird can distinguish this subtle change in song speed as can be seen from the prediction errors of the causal states at all three levels. (The hidden states show similar prediction errors at all levels).
